Lumbar Spine Conditions: Lower Back Pain
Introduction
The lumbar spine (lower back) is the most load-bearing region of the spine. It forms the lower portion of the spinal column and is made up of five large vertebrae (L1–L5) designed to support body weight while allowing movement. If you would like a clearer overview of how the spine is structured, see our guide to spinal anatomy and how the spine works.
It allows bending, lifting, walking, and sitting while protecting the nerve roots that travel into the legs.

Because of these mechanical demands, the lumbar spine is the most common source of back pain and nerve-related leg symptoms. Lower back and leg pain can arise from several structures including disc irritation, nerve root involvement, joint irritation, muscular overload, spinal canal narrowing, or a combination of factors. For example, symptoms may relate to problems such as lumbar disc degeneration, irritation of the facet joints in the lower back, or conditions that narrow the space around the nerves such as lumbar spinal stenosis.
One of the reasons back pain can feel confusing is that several different lumbar spine problems can produce very similar symptoms. For example, nerve irritation, disc changes, joint irritation, or narrowing around the nerves can all produce pain that spreads into the buttock or leg. Understanding the underlying cause is therefore important when deciding on the most appropriate treatment.
Identifying the primary cause of symptoms is essential. Effective management depends on distinguishing between mechanical sensitivity, nerve irritation, age-related structural change, joint irritation, and more specific lumbar conditions.
Each major lumbar condition is outlined below. Select the page that most closely matches your symptoms for a detailed explanation and management guidance.
In addition, we have dedicated patient education pages that address common questions — such as imaging findings, recovery timelines, exercise guidance, and when to seek urgent review. These are designed to provide deeper clarity beyond diagnostic labels and can be found at the bottom of the page.
Non-Specific Lower Back Pain
This is the most common type of lower back pain. Symptoms are usually localised to the lower back and may feel stiff, tight, or sore. Pain often fluctuates with posture and activity and does not usually cause progressive leg weakness or significant neurological symptoms.
Most episodes improve with proportionate load management and progressive rehabilitation.
Many people assume that persistent lower back pain must always be related to a damaged disc or trapped nerve, but most episodes of back pain fall into this non-specific category where symptoms relate more to mechanical sensitivity than structural injury. You can read more about this in our guide to non-specific low back pain.
Lumbar Disc Herniation (Slipped Disc)
The term “slipped disc” is commonly used to describe a lumbar disc herniation, where part of the disc bulges or protrudes and may irritate a nearby nerve root. This can cause lower back pain combined with leg symptoms such as tingling, numbness, or pain travelling below the knee, often described as sciatica.
Symptoms often worsen with sitting, coughing, or prolonged bending. In rare cases this is one of the primary reasons for the onset of Cauda Equina Syndrome, a serious condition that requires urgent medical assessment and attention.
The symptoms may seem similar to those caused by lumbar spine stenosis which has it's own page, but the cause is very different, as is the treatment.
Sciatica
Sciatica describes a symptom pattern where irritation of the sciatic nerve causes pain that travels from the lower back into the buttock and down the leg. Many experienced clinicians view sciatica as a symptom rather than a diagnosis however, and the dedicated article in our patient knowledge centre, (which hosts articles based more on patient led questions, versus specific conditions), digs in to this topic deeper.
Leg-dominant pain, pins and needles, burning sensations, or electric-type pain are common features. Not all leg pain is true sciatica, which is why proper assessment matters.
Lumbar Degenerative Disc Disease (DDD)
This conditions sounds serious but in reality it is a commonly seen MRI description of 'age-related disc' changes. It is regularly seen in people without pain, and therefore is not automatically the cause of symptoms. Understanding context is vital to prevent unnecessary fear.
A common question due to the use of 'disease' in the title, is how do we cure it? In reality degenerative disc disease is is not a disease in the truest sense.
Lumbar Spinal Stenosis
Lumbar spinal stenosis refers to narrowing within the spinal canal that may affect nerve roots. It is more common with increasing age. It should not be confused with other causes of neurological leg pains such as stenosis.
Typical symptoms include leg heaviness, aching, or weakness when walking, often relieved by sitting or bending forward. Walking tolerance may gradually reduce over time.
Lumbar Facet Joint Pain
The facet joints are small stabilising joints at the back of the spine. Irritation here typically causes localised lower back pain, often one-sided, sometimes referring into the buttock or upper thigh but rarely below the knee.
Pain is commonly aggravated by prolonged standing, extension (leaning back), or twisting movements.
Spondylolisthesis and Retrolisthesis
A small shift of one vertebra relative to another. Can be incidental or associated with back pain and occasionally leg symptoms.

Cauda Equina Syndrome (CES) - EMERGENCY
Rare, but urgent. Although most lumbar spine conditions are mechanical and improve with appropriate management, certain symptoms require urgent medical attention. If your symptoms may include new bladder or bowel disturbance, numbness around the saddle/groin region, or rapidly worsening leg weakness you require immediate emergency assessment.
Imaging of the Lumbar Spine
Sometimes people worry that back pain automatically means a serious structural problem that requires a scan. In reality, most lumbar spine problems can be diagnosed clinically. Our guide to MRI scans, X-rays and CT scanning explains when imaging may be helpful and when it is unlikely to change management.
Low back Pain and Chris Heywood Physio
If you are dealing with persistent back pain, leg pain, or sciatica and want a clear diagnosis, you can learn more about assessment and treatment at Chris Heywood Physio. With over 25 years of clinical experience managing complex spinal conditions, I am also frequently asked to provide second or third opinions for patients seeking greater clarity about their diagnosis or treatment options.
Physiotherapy FAQ's
1. Do I need a GP referral to see a physiotherapist?
No. Physiotherapists are primary healthcare practitioners, which means that if you are self-funding your treatment, you can usually book an appointment directly without a referral from a GP or consultant.
If you are planning to use private health insurance, the requirements may vary depending on the policy and insurance provider. Some insurers require a GP or consultant referral before physiotherapy treatment can begin, so it is advisable to check with your insurance company before booking.
2. What should I wear to a physiotherapy appointment?
Comfortable clothing that allows the relevant area of the body to be examined is helpful. For example, shorts may be useful for knee or leg problems, while a vest top may help for shoulder or neck injuries.
More detailed information about preparing for your appointment can be found on the physiotherapy assessment page.
3. How long is a physiotherapy appointment?
Appointments with Chris Heywood Physio last 60 minutes. This allows time for a detailed assessment, explanation of the problem, and treatment where appropriate.
4. Will I receive treatment at the first appointment?
In most cases treatment will begin during the first appointment once the assessment has been completed and the problem has been explained.
However, if the clinical findings suggest that immediate treatment is not appropriate, this will be discussed and the most suitable next steps explained.
5. How many physiotherapy sessions will I need?
The number of sessions required varies depending on the nature of the injury and how the body responds to treatment.
Some problems improve quickly with appropriate advice and rehabilitation exercises, while others may require a longer period of recovery. Treatment recommendations are always based on clinical findings rather than a preset treatment schedule.
6. Can physiotherapy help long-standing injuries?
Yes. Physiotherapy can often help identify factors contributing to persistent pain or recurring injuries and guide appropriate rehabilitation strategies to improve movement, strength, and function.
7. Is physiotherapy only for sports injuries?
No. Physiotherapy can help with a wide range of musculoskeletal problems including back pain, joint pain, tendon problems, work-related injuries, and persistent movement issues. Physiotherapy may also support recovery before or after surgery, helping improve strength, mobility, and function during the rehabilitation process.
Many people attending physiotherapy are simply looking for help with pain that affects everyday activities such as walking, working, exercising, or sleeping comfortably.
8. What if physiotherapy is not the right treatment for me?
If physiotherapy is unlikely to help, or if further medical investigation may be appropriate, this will be explained clearly.
Patients are always given honest advice about the most appropriate next steps for their situation.
