Quick answer
What is Spinal stenosis?
Spinal stenosis is a narrowing of the spaces within the spine, which can put pressure on the spinal cord and the nerves that travel through it. It most commonly affects the lower back (lumbar spinal stenosis) and usually develops gradually with age-related changes such as arthritis, thickened ligaments and bulging discs.
- How it is treated: Many people are managed without surgery, and treatment is tailored to the severity.
- Self-care: Staying active within comfort, doing prescribed physiotherapy and core-strengthening exercises, maintaining a healthy weight, and finding positions and activities that ease symptoms (such as cycling or leaning forward) all help manage spinal stenosis.
- When to seek help: See a GP for back and leg pain brought on by walking and eased by sitting or bending forward.
What it is
Spinal stenosis is a narrowing of the spaces within the spine, which can put pressure on the spinal cord and the nerves that travel through it. It most commonly affects the lower back (lumbar spinal stenosis) and usually develops gradually with age-related changes such as arthritis, thickened ligaments and bulging discs. A characteristic feature of lumbar stenosis is pain, aching, numbness or weakness in the legs and buttocks that comes on with walking or standing and is relieved by sitting or bending forward. Stenosis in the neck can cause symptoms in the arms and, if the cord is significantly affected, problems with balance or hand function. It is diagnosed from the symptoms and imaging such as an MRI scan.
How it is treated
Many people are managed without surgery, and treatment is tailored to the severity. Measures include staying active within comfort, exercise and physiotherapy to strengthen and improve posture and mobility, pain relief, and activity adaptations (many people find cycling or leaning on a trolley easier than upright walking). Some people benefit from spinal injections to reduce inflammation and pain. When symptoms are severe, persistent and significantly limiting despite these measures — or if there are signs of serious nerve compression — surgery to create more space for the nerves can be very effective. The right approach is individual and guided by a specialist. New bladder or bowel problems or leg weakness are treated as an emergency.

Beyond medication
Lifestyle and self-care
Staying active within comfort, doing prescribed physiotherapy and core-strengthening exercises, maintaining a healthy weight, and finding positions and activities that ease symptoms (such as cycling or leaning forward) all help manage spinal stenosis.
When to get help
When to see a doctor
See a GP for back and leg pain brought on by walking and eased by sitting or bending forward. Seek emergency care (999/A&E) for new numbness around the groin, loss of bladder or bowel control, or worsening leg weakness (possible cauda equina syndrome).
Not sure how urgent it is? It is always OK to call NHS 111 for advice, day or night.
Answers
Spinal stenosis: frequently asked questions
What is the typical symptom of lumbar spinal stenosis?
Pain, aching, numbness or weakness in the legs and buttocks that comes on with walking or standing and is relieved by sitting or bending forward. Many people find leaning on a trolley or cycling easier than upright walking.
Does spinal stenosis need surgery?
Often not — many people are managed with exercise, physiotherapy, pain relief and sometimes injections. Surgery to create more space for the nerves is considered when symptoms are severe and limiting despite these measures.
