Achilles Tendinopathy
A common cause of pain at the back of the heel linked to overload of the Achilles tendon
Get WISE - Get WELL
- Get ON
Achilles tendinopathy is a common cause of pain and stiffness at the back of the ankle. The condition affects the Achilles tendon, the strong fibrous structure that connects the calf muscles to the heel bone.
The Achilles tendon plays a crucial role during walking, running, and jumping. Each step requires the tendon to transmit force from the gastrocnemius and soleus muscles of the calf to the foot. During activities such as running, the tendon may be exposed to forces several times greater than body weight.
Under normal circumstances the tendon is well adapted to tolerate these forces. However, when the mechanical demands placed on the tendon increase faster than the tissue can adapt, the tendon can become irritated and painful. This process is commonly described as Achilles tendinopathy.

Understanding the Achilles tendon
The Achilles tendon is the strongest tendon in the human body and plays a critical role in transmitting force during walking, running, and jumping.
It forms where the two major calf muscles — the gastrocnemius and soleus — merge in the lower leg before attaching to the back of the calcaneus (heel bone). When these muscles contract, force is transmitted through the tendon to allow the foot to push against the ground.
During normal walking, the Achilles tendon experiences forces of roughly three to four times body weight. During running or jumping these forces may increase substantially, sometimes exceeding eight times body weight.
Despite its strength, the tendon must tolerate these forces thousands of times during everyday activities. For this reason, small changes in how the tendon is loaded can have a significant effect over time.
Tendon structure and adaptation
Tendons are specialised connective tissues designed to transmit force between muscles and bones.
The Achilles tendon is primarily composed of tightly organised collagen fibres, arranged in parallel bundles that allow the tendon to resist tensile forces. This structure gives the tendon both strength and a small degree of elasticity.
Like other connective tissues, tendons have the ability to adapt to mechanical loading. When exposed to regular stress, the tissue can gradually remodel and strengthen. This process is the basis for how exercise improves tendon resilience.
However, tendon adaptation occurs relatively slowly compared with muscle. If loading increases faster than the tissue can adapt, the tendon may begin to develop structural changes that lead to pain and stiffness.

The development of Achilles tendinopathy
Achilles tendinopathy is thought to develop when the balance between tendon loading and tendon adaptation becomes disrupted.
Instead of responding positively to mechanical stress, the tendon begins to show changes within its internal structure. These changes may include:
• disruption of collagen fibre alignment
• increased water content within the tendon
• thickening of the tendon structure
• increased nerve and blood vessel growth within the tissue
These structural changes are often referred to collectively as tendinopathy. Importantly, research has shown that inflammation is not always the primary process in these conditions. For this reason, many clinicians now prefer the term tendinopathy rather than tendonitis.
Why the Achilles tendon is particularly vulnerable
Several factors make the Achilles tendon more susceptible to overload.
1. High mechanical forces
Because the tendon transmits large forces during walking and running, even small increases in activity levels can significantly increase the stress placed on the tissue.
2. Limited blood supply
The mid-portion of the Achilles tendon has a relatively limited blood supply compared with other areas of the tendon. This may partly explain why problems often develop in this region.
3. Repetitive loading
Activities such as running, jumping, and hill walking repeatedly expose the tendon to high forces, increasing the risk of overload if the tissue is not adequately conditioned.
Mid-portion vs insertional Achilles tendinopathy
Achilles tendinopathy is often divided into two main clinical patterns depending on where symptoms occur along the tendon. Although both conditions involve the same tendon, the mechanical stresses affecting each region can be quite different. For this reason, understanding the location of symptoms is often important when assessing the problem and planning rehabilitation.
Mid-portion Achilles tendinopathy
Mid-portion tendinopathy occurs in the section of the tendon located approximately 2–6 centimetres above the heel bone. This is the most common form of Achilles tendinopathy and is particularly common in people involved in running or repetitive impact activities.
Several anatomical factors may contribute to why this region is vulnerable. The tendon narrows slightly in this area and has a relatively reduced blood supply compared with other parts of the tendon. These factors may influence how the tissue responds to repeated loading.
Symptoms in mid-portion tendinopathy are usually felt slightly higher up the tendon rather than directly at the heel bone. People often describe a localised area of tenderness or thickening along the tendon that becomes painful during activity.
Over time, the tendon may become visibly thicker as the tissue adapts to repeated mechanical stress. Mid-portion tendinopathy often develops gradually in association with changes in activity levels, such as:
• increases in running distance
• hill training or speed work
• returning to sport after a break
• sudden increases in walking or exercise
Because the tendon is repeatedly loaded during these activities, the tissue may gradually become irritated if the loading increases faster than the tendon can adapt.
Insertional Achilles tendinopathy
Insertional tendinopathy occurs where the Achilles tendon attaches directly to the calcaneus (heel bone). In this form of the condition, pain is usually located at the back of the heel rather than higher up the tendon. The mechanical stresses affecting the tendon insertion can differ from those affecting the mid-portion of the tendon.
Compression of the tendon against the heel bone during ankle movement may play a role in some cases. Insertional tendinopathy may sometimes occur alongside irritation of nearby structures, including:
• the retrocalcaneal bursa
• small bony prominences of the heel (Haglund's Deformity)
• degenerative changes at the tendon attachment
These factors can influence how the condition behaves and may sometimes affect the type of rehabilitation exercises that are recommended.
Because of these differences, distinguishing between mid-portion and insertional tendinopathy can be helpful when planning treatment strategies.
Typical symptom behaviour
Achilles tendinopathy often follows a characteristic pattern of symptoms that reflects how the tendon responds to mechanical loading. In many cases symptoms begin gradually. Early on, discomfort may only occur during or after activity, particularly activities that place higher loads on the tendon such as running, hill walking, or jumping.
As the condition progresses, the tendon may become increasingly sensitive to loading and symptoms may begin to appear during everyday activities.
One of the most commonly reported features of Achilles tendinopathy is morning stiffness in the tendon. This occurs because the tendon is relatively unloaded during sleep, which can allow the tissue to stiffen slightly. The first few steps in the morning then place tension on the tendon, which can trigger discomfort.
Typical symptom patterns may include:
• stiffness in the Achilles tendon when first getting out of bed
• pain during running or brisk walking
• discomfort when walking uphill or climbing stairs
• tenderness when pressing directly on the tendon
• gradual thickening of the tendon over time
In early stages of the condition, pain may settle relatively quickly once activity stops. However, in more persistent cases the tendon may remain painful during everyday movements.
Understanding how symptoms behave during activity and rest is often an important part of the diagnostic process.
Imaging findings
Imaging is not always required to diagnose Achilles tendinopathy. In many cases the condition can be diagnosed based on the clinical history and physical examination alone. However, imaging may sometimes be used when the diagnosis is uncertain or when other conditions need to be ruled out.
Ultrasound and MRI scans are the most commonly used investigations for assessing the Achilles tendon.
Ultrasound imaging
Ultrasound scans can visualise the tendon structure in real time and may show:
• thickening of the tendon
• changes in collagen fibre organisation
• increased blood vessel growth within the tendon
Ultrasound is particularly useful for assessing the structure of the tendon and surrounding soft tissues.
You can read more about this investigation here:
MRI imaging
MRI scans provide detailed images of both bone and soft tissue structures. They may show:
• changes within the tendon structure
• surrounding soft tissue irritation
• problems affecting nearby structures
MRI may occasionally be used when symptoms are severe, persistent, or when other causes of pain need to be excluded.
More information about this type of imaging can be found here:
Interpreting imaging findings
It is important to note that structural changes seen on imaging do not always correspond directly with symptoms.
Research has shown that some people have tendon changes visible on scans even though they experience no pain at all. For this reason, imaging findings must always be interpreted alongside the clinical examination and patient history.
Relationship with other lower-limb conditions
The Achilles tendon functions as part of a larger mechanical system within the lower limb. During walking and running, the tendon works closely with several other structures in the foot and ankle to absorb and transmit forces.
Reduced ankle flexibility, particularly limited dorsiflexion, can increase the stress placed on the Achilles tendon during movement. Similarly, tightness in the calf muscles can alter how forces are transmitted through the ankle joint.
Conditions affecting other structures in the foot may also influence how the Achilles tendon is loaded. For example, problems affecting the plantar fascia can sometimes alter the mechanics of the foot and increase the demands placed on the Achilles tendon during walking.

Rehabilitation of Achilles tendinopathy
Rehabilitation of Achilles tendinopathy usually focuses on gradually restoring the tendon’s ability to tolerate mechanical load. Because the Achilles tendon is exposed to large forces during everyday activities, recovery typically involves carefully increasing the amount of load placed on the tendon so that the tissue can gradually adapt.
This process is sometimes referred to as progressive tendon loading.
Unlike muscles, tendons adapt relatively slowly. For this reason, rehabilitation programmes are usually introduced gradually and progressed over time.
Why loading exercises are important
Tendons respond positively to controlled mechanical loading. When a tendon is exposed to repeated stress at an appropriate level, the tissue can gradually remodel and strengthen. This process helps the tendon tolerate greater forces during activity.
For this reason, rehabilitation programmes for Achilles tendinopathy often include exercises that progressively load the tendon.
Without this gradual loading process, the tendon may remain sensitive and struggle to cope with normal activity.
You may also find it helpful to read:
Types of loading exercises used in rehabilitation
Several types of exercise programmes have been used in the rehabilitation of Achilles tendinopathy. Although the exact approach may vary between individuals, most programmes aim to gradually increase the load placed on the tendon.
Common approaches include:
Eccentric loading exercises
Eccentric exercises involve strengthening the muscle while it is lengthening under load. For the Achilles tendon, this often involves controlled lowering movements such as slowly lowering the heel below the level of a step.
Eccentric loading programmes became widely used after early research suggested they could help improve symptoms in people with chronic Achilles tendinopathy. Although eccentric exercises are still commonly used, many clinicians now combine them with other loading strategies.
Heavy slow resistance training
Heavy slow resistance training involves strengthening the calf muscles using slow, controlled movements under increasing resistance.
This type of programme often includes exercises such as:
• calf raises
• seated calf strengthening
• progressive loading using weights or resistance machines
The aim is to gradually increase the tendon’s tolerance to load over time.
Gradual return to activity
For individuals involved in running or sport, rehabilitation also involves gradually returning to the activities that place the greatest load on the tendon.
This process may involve:
• temporarily reducing training volume
• reintroducing running gradually
• avoiding sudden increases in intensity
Managing how quickly activity levels increase is often an important part of preventing symptoms from returning.
Factors that may influence recovery
Several factors can influence how the Achilles tendon responds to rehabilitation. These may include:
• the duration of symptoms
• overall activity levels
• calf muscle strength
• ankle mobility
• underlying health conditions
For this reason, rehabilitation programmes are usually tailored to the individual rather than following a single fixed protocol.
Additional treatments
Exercise-based rehabilitation remains the central component of treatment for Achilles tendinopathy. Progressive loading programmes designed to strengthen the calf muscles and gradually improve the tendon’s ability to tolerate mechanical stress form the foundation of most rehabilitation strategies.
However, in some cases symptoms may persist despite appropriate rehabilitation. This can occur for a variety of reasons, including long-standing tendon changes, repeated mechanical stress from activity, or difficulty modifying loading patterns during daily life.
In these situations, additional treatment approaches may sometimes be considered alongside rehabilitation exercises.
Shockwave therapy
Shockwave therapy is sometimes used in cases of persistent tendon pain that have not responded to rehabilitation alone.
This treatment involves the application of high-energy acoustic waves to the affected tissue. The precise mechanism is not fully understood, but the therapy is thought to stimulate biological processes that may promote tissue healing and reduce pain.
Shockwave therapy has been studied in several tendon-related conditions, including Achilles tendinopathy and plantar fasciitis, and may be considered in cases where symptoms have been present for a prolonged period.
You can read more about this treatment here:
Activity modification
Adjusting activity levels is often an important part of managing persistent tendon pain. Because the Achilles tendon is exposed to large forces during activities such as running, jumping, and hill walking, temporarily modifying these activities can sometimes help reduce excessive stress on the tendon while rehabilitation exercises are introduced.
This does not usually mean complete rest. Instead, the aim is often to maintain general activity while temporarily reducing the activities that place the greatest strain on the tendon.
Gradual reintroduction of these activities is then incorporated into the rehabilitation process as the tendon becomes more tolerant to load.
Addressing biomechanical factors
In some individuals, biomechanical factors affecting the foot and ankle may influence how the Achilles tendon is loaded.
Examples may include:
• reduced ankle dorsiflexion
• tightness in the calf muscles
• altered foot mechanics during walking or running
• changes in footwear
Identifying and addressing these factors may sometimes help reduce excessive strain on the tendon and support the rehabilitation process.
Because the Achilles tendon works closely with other structures in the foot and ankle, it may also be helpful to understand related conditions affecting these areas.
You may therefore find it helpful to read:
• Plantar Fasciitis
• Lower Limb Conditions Hub
Why rehabilitation takes time
Recovery from Achilles tendinopathy usually occurs gradually rather than immediately. This is largely because tendon tissue adapts slowly to changes in mechanical loading. Unlike muscle tissue, which can respond relatively quickly to strengthening exercises, tendons require longer periods of consistent loading before meaningful structural adaptation occurs.
During rehabilitation, exercises are therefore introduced progressively to allow the tendon to adapt without becoming excessively irritated.
If loading increases too quickly, the tendon may become sensitive again and symptoms may temporarily worsen. For this reason, rehabilitation programmes typically progress gradually, with careful attention paid to how the tendon responds to changes in activity.
Because tendons respond best to consistent and progressive loading, maintaining a structured rehabilitation programme is often more effective than alternating between periods of intense exercise and complete rest.
The importance of long-term tendon health
Even after symptoms improve, maintaining tendon strength can help reduce the risk of symptoms returning. The Achilles tendon is exposed to repeated mechanical forces during everyday activities, particularly walking, running, and sport.
Maintaining adequate strength and flexibility in the calf muscles helps distribute these forces more effectively and may reduce the likelihood of the tendon becoming overloaded again.
For individuals who participate in sports or activities that involve repetitive loading of the tendon, continuing appropriate strengthening exercises may help maintain the tendon’s ability to tolerate these stresses.
Gradual progression of activity levels, particularly when returning to running or high-impact activities, can also play an important role in preventing recurrence of symptoms.
Because the Achilles tendon works closely with other structures in the lower limb, maintaining good strength and mobility throughout the foot and ankle can contribute to overall tendon resilience.
Conditions that can be mistaken for Achilles tendinopathy
Not all pain at the back of the heel is caused by Achilles tendinopathy. Although the Achilles tendon is a common source of symptoms in this region, several other conditions can produce similar pain patterns. For this reason, careful clinical assessment is important when symptoms do not follow the typical pattern of tendon overload.
Understanding the possible alternative causes of heel pain helps ensure that the correct diagnosis is made and that appropriate management strategies are used.
Retrocalcaneal bursitis
Retrocalcaneal bursitis occurs when the bursa located between the Achilles tendon and the heel bone becomes irritated.
A bursa is a small fluid-filled sac that helps reduce friction between tissues. The retrocalcaneal bursa sits between the Achilles tendon and the calcaneus (heel bone) and allows the tendon to glide smoothly during ankle movement.
When this structure becomes irritated, pain may develop at the back of the heel, often close to where the Achilles tendon attaches to the bone.
Symptoms may include:
• pain directly at the back of the heel
• swelling near the tendon insertion
• discomfort when the ankle is moved into dorsiflexion
• irritation when wearing shoes with a rigid heel counter
In some cases retrocalcaneal bursitis may occur alongside insertional Achilles tendinopathy, as both conditions affect structures in the same region.
Achilles tendon rupture
A rupture of the Achilles tendon is a more serious injury that involves a partial or complete tear of the tendon fibres.
This injury usually occurs suddenly, often during activities involving rapid acceleration or jumping. People frequently describe feeling a sudden pain in the back of the ankle, sometimes accompanied by a sensation of being struck or kicked in the heel.
Common features may include:
• sudden pain in the Achilles tendon
• difficulty pushing off the foot
• weakness when attempting to stand on the toes
• swelling or bruising around the tendon
Because a rupture requires prompt medical assessment, it is important to seek medical attention if a sudden injury occurs in this region.
Calcaneal stress fractures
Stress fractures of the heel bone can sometimes cause pain in a similar location to Achilles tendon problems.
Stress fractures occur when repetitive mechanical loading gradually creates small cracks within the bone. These injuries are most commonly seen in individuals who have recently increased their training volume or impact activity.
Symptoms may include:
• deep pain within the heel
• pain that worsens with weight-bearing activity
• tenderness when the heel bone is compressed
Unlike tendon pain, which is often felt within the soft tissue of the tendon itself, stress fractures may produce a deeper or more diffuse pain within the heel.
Nerve-related pain
Pain near the heel can occasionally originate from irritation of nearby nerves. Compression of nerves around the ankle or foot may produce symptoms that resemble tendon problems. In some cases this may cause burning pain, tingling, or altered sensation around the heel or sole of the foot.
One example is tarsal tunnel syndrome, where the tibial nerve becomes compressed near the inside of the ankle.
Although this condition is less common than Achilles tendinopathy, it may be considered if symptoms include nerve-like sensations rather than typical tendon pain.
Risk factors for Achilles tendinopathy
Achilles tendinopathy often develops when several contributing factors combine to increase the mechanical stress placed on the tendon. In many cases there is no single cause. Instead, the condition develops gradually when changes in activity, biomechanics, or tissue health increase the load placed on the tendon beyond its ability to adapt.
Understanding these factors can help explain why symptoms develop and may also help reduce the risk of the condition returning in the future.
Sudden changes in activity levels
One of the most common triggers for Achilles tendinopathy is a rapid increase in physical activity. The Achilles tendon adapts slowly to increases in mechanical loading. When activity levels increase suddenly — for example when running distances increase rapidly or new training routines are introduced — the tendon may be exposed to stresses that it has not yet adapted to tolerate.
Examples of activity-related changes that may increase tendon stress include:
• increasing running mileage too quickly
• introducing hill running or sprint training
• returning to sport after a period of inactivity
• increasing walking or standing demands at work
Gradual progression of activity levels is therefore often an important strategy for reducing tendon overload.
Reduced ankle flexibility
Limited ankle dorsiflexion (pulling ankle upwards)can increase the load placed on the Achilles tendon during movement. When the ankle joint has restricted movement, the calf muscles and Achilles tendon may be forced to absorb greater forces during walking or running. Over time this increased strain may contribute to irritation of the tendon.
Reduced ankle mobility may occur as a result of:
• calf muscle tightness
• previous ankle injuries
• prolonged periods of reduced activity
Improving ankle mobility is therefore often included as part of rehabilitation programmes for Achilles tendinopathy.
Calf muscle weakness
Weakness in the calf muscles can alter how forces are transmitted through the Achilles tendon. The gastrocnemius and soleus muscles work together with the Achilles tendon to control movement at the ankle. If these muscles are unable to generate sufficient force, the tendon may experience abnormal loading patterns during activity.
For this reason, rehabilitation programmes for Achilles tendinopathy often include progressive strengthening of the calf muscles.
Age-related tendon changes
The risk of tendon problems tends to increase gradually with age. As people get older, the structure and elasticity of tendon tissue can change. These changes may reduce the tendon’s ability to tolerate repeated mechanical stress. Although Achilles tendinopathy can occur at any age, it is more commonly seen in adults who participate in running or recreational sport.
Training surface and footwear
External factors such as footwear and training surfaces can influence how forces are transmitted through the Achilles tendon. Running on very hard surfaces, changing footwear suddenly, or wearing shoes that alter ankle mechanics can all influence how the tendon is loaded during movement.
For example:
• running on uneven terrain may increase tendon strain
• shoes with very low heel-to-toe drop may increase Achilles loading
• worn or unsupportive footwear may alter foot mechanics
Although these factors are rarely the sole cause of tendon pain, they can sometimes contribute when combined with other risk factors.
Other contributing factors
Several additional factors may also influence tendon health. These may include:
• prolonged periods of standing at work
• reduced general physical conditioning
• previous tendon injuries
• metabolic or systemic health conditions - see bext section
In many cases Achilles tendinopathy develops when multiple factors interact, gradually increasing the mechanical stress placed on the tendon.
Hormonal and systemic influences on tendon health
Tendon health can also be influenced by hormonal and systemic factors that affect how connective tissue adapts to mechanical loading. Hormones play an important role in regulating collagen metabolism and tissue repair. Changes in hormonal levels may therefore influence how tendons respond to repeated mechanical stress.
For example, oestrogen is known to affect collagen turnover and tendon elasticity. Changes in hormone levels that occur during different stages of life may therefore alter how tendons respond to physical activity.
In women, tendon-related symptoms may sometimes occur more frequently during periods of hormonal change, such as:
• pregnancy
• the postpartum period
• perimenopause and menopause
These hormonal changes may influence tendon stiffness, collagen structure, and the ability of the tissue to adapt to mechanical loading.
Metabolic and systemic health
Certain metabolic or systemic health conditions can also affect tendon structure and resilience. Research has shown associations between tendon disorders and conditions that influence collagen metabolism or tissue healing, including:
• diabetes
• metabolic syndrome
• inflammatory conditions
• certain medications such as fluoroquinolone antibiotics or corticosteroids
These factors do not necessarily cause Achilles tendinopathy directly, but they may influence the tendon’s ability to tolerate repeated mechanical stress.
Why these factors matter
Although mechanical loading remains the primary driver of most tendon problems, systemic influences can sometimes affect how well tendons adapt to stress or recover from injury.
For this reason, a full clinical assessment may sometimes consider both mechanical and systemic factors when evaluating persistent tendon problems.
Why understanding risk factors matters
Identifying the factors that contributed to the development of Achilles tendinopathy can be helpful when planning rehabilitation and reducing the risk of symptoms returning.
For example, improving calf strength, gradually progressing activity levels, and addressing ankle mobility limitations may help the tendon tolerate mechanical loading more effectively.
Because the Achilles tendon works closely with other structures in the lower limb, it may also be helpful to understand related conditions affecting the foot and ankle.
Summary
Achilles tendinopathy is a common cause of pain at the back of the ankle and usually develops when the mechanical load placed on the Achilles tendon exceeds the tissue’s ability to adapt.
The Achilles tendon is responsible for transmitting force from the calf muscles to the foot during walking, running, and jumping. Because it is exposed to large forces during these activities, even relatively small changes in activity levels or biomechanics can increase the stress placed on the tendon.
Over time this repeated loading may lead to structural changes within the tendon that result in pain, stiffness, and reduced tolerance to activity. Symptoms often develop gradually and may initially appear during exercise before progressing to discomfort during everyday movement.
Diagnosis is usually based on clinical assessment, although imaging such as ultrasound or MRI scans may occasionally be used when the diagnosis is uncertain or when other conditions need to be excluded.
Rehabilitation typically focuses on gradually restoring the tendon’s ability to tolerate load, often through progressive strengthening exercises for the calf muscles and careful management of activity levels.
Because tendon tissue adapts slowly, recovery often occurs gradually over several weeks or months. However, with appropriate management many people are able to return to normal activity levels and maintain long-term tendon health.

Frequently Asked Questions About Achilles Tendinopathy
1) What is the difference between Achilles tendinopathy and Achilles tendonitis?
The terms are often used interchangeably, but they do not necessarily describe the same process.
Historically the condition was often called Achilles tendonitis, implying that inflammation was the main cause of symptoms. However, research has shown that many long-standing tendon problems involve structural changes within the tendon rather than purely inflammatory processes.
For this reason, many clinicians now prefer the term Achilles tendinopathy, which describes a broader range of tendon-related changes.
2) Why is Achilles tendon pain often worse in the morning?
Morning stiffness is a common feature of many tendon conditions.
During sleep the Achilles tendon is relatively unloaded for several hours, which can allow the tissue to stiffen slightly. When the first steps are taken in the morning, the tendon is suddenly stretched again, which can produce discomfort until the tissue warms up and becomes more flexible.
3) Can Achilles tendinopathy heal on its own?
Some cases improve gradually with sensible activity modification.
Reducing activities that heavily load the tendon while gradually reintroducing strengthening exercises may allow the tendon to adapt and recover over time.
However, persistent cases often benefit from a structured rehabilitation programme designed to progressively improve the tendon’s ability to tolerate mechanical load.
4) Should I completely rest if I have Achilles tendon pain?
Complete rest is rarely the most effective approach.
While temporarily reducing aggravating activities may help calm symptoms, tendons generally respond best to carefully controlled loading rather than total inactivity.
Progressive strengthening exercises are often used to gradually restore the tendon’s tolerance to mechanical stress.
5) Are scans needed to diagnose Achilles tendinopathy?
In most cases imaging is not required.
Diagnosis is usually made through clinical assessment, based on the history of symptoms and findings during physical examination.
Scans such as ultrasound or MRI may sometimes be used when the diagnosis is uncertain or when other conditions affecting the heel need to be ruled out.
6) Can running cause Achilles tendinopathy?
Sudden increases in running load are one of the most common triggers.
Running places significant stress on the Achilles tendon. If training volume or intensity increases too quickly, the tendon may be exposed to loads that it has not yet adapted to tolerate.
Gradual progression of training levels is therefore an important factor in preventing tendon overload.
7) How long does Achilles tendinopathy usually take to recover?
Recovery times vary depending on how long the symptoms have been present and how the tendon responds to rehabilitation.
Early cases may improve within several weeks once aggravating activities are modified. More persistent cases may require several months of progressive rehabilitation to restore the tendon’s tolerance to load.
Because tendon tissue adapts slowly, improvement often occurs gradually.
8) Can Achilles tendinopathy return after recovery?
Symptoms can sometimes return if the tendon is exposed to sudden increases in mechanical stress.
Maintaining adequate calf strength, gradually progressing activity levels, and avoiding sudden changes in training intensity may help reduce the risk of recurrence.
Understanding the factors that contributed to the original problem is often helpful in preventing symptoms from returning.
