Lumbar spinal stenosis is a narrowing of the spaces in the lower spine where the nerves run, usually caused by age-related changes. It typically causes pain, heaviness or tingling in the buttocks and legs when standing or walking, which eases when sitting or bending forward. This pattern is called neurogenic claudication.
Also known as spinal stenosis, neurogenic claudication, narrowing of the spinal canal
Symptoms
- Pain, aching, heaviness or cramping in the buttocks and legs when walking or standing
- Symptoms that ease when sitting down or bending forward, for example leaning on a shopping trolley
- Pins and needles or numbness in the legs
- Reduced walking distance
- Low back pain and stiffness
- Legs feeling weak or tired
Causes and risk factors
- Age-related thickening of ligaments and enlargement of the facet joints
- Disc bulging and loss of disc height
- Degenerative spondylolisthesis (one vertebra slipping forward on another)
- Less commonly, a naturally narrow spinal canal
What the evidence says helps
- An updated systematic review found moderate-quality evidence that a combined approach including manual therapy and exercise, with or without education, improves symptoms and function in the short term.2
- A clinical practice guideline suggests starting with multimodal non-drug care: education, lifestyle advice, home exercise, manual therapy and rehabilitation.3
- In a randomised trial of people who were candidates for surgery, a physiotherapy programme gave similar improvements in physical function to decompression surgery at two years, although many people later chose surgery.5
- A Cochrane review could not say with confidence whether surgery or non-surgical care is better. Side effects were reported in 10–24% of surgical cases, and none for conservative treatments.4
- NICE advises against epidural injections for neurogenic claudication caused by central spinal stenosis, and a review found epidural steroids were not effective for this condition.26
Things you can try at home
- Keep walking, using short bouts with rests, and build up distance gradually
- Try cycling or a recumbent bike – many people tolerate forward-leaning activities better
- Use a walking pole or trolley to lean forward slightly if it helps you walk further
- Include regular strength exercises for the legs and trunk
- Sit down and lean forward to ease symptoms when they build up
When to get urgent help
Contact your GP urgently, call NHS 111, or call 999 in an emergency if you have:
- Numbness around your genitals, bottom or inner thighs, or new bladder or bowel problems – go to A&E or call 999 immediately
- Rapidly worsening weakness or numbness in one or both legs – seek urgent medical help
- Leg pain on walking that eases with standing still (not sitting), with cold, pale feet – see your GP urgently, as this can be a circulation problem
- Back pain with fever, unexplained weight loss or a history of cancer – see your GP urgently
- Frequent falls or new unsteadiness on your feet – see your GP urgently
How Apollo can help
We assess your walking, strength, balance and nerve function, and help you understand how your symptoms behave. Our approach combines graded exercise, walking programmes, education and hands-on care where suitable, in line with the multimodal care supported by research. We can also provide supervised clinical exercise, prehab and rehab around surgery, and refer you to your GP if you need further investigation.
No GP referral needed. Clinics in Sheringham, Coltishall and Norwich.

Frequently asked questions
Why does bending forward ease spinal stenosis pain?
Bending forward slightly opens the spaces where the nerves run in the lower spine. Standing upright or leaning back narrows them. That is why sitting, cycling or leaning on a trolley often feels easier.
Does spinal stenosis always need surgery?
No. Many people manage well with exercise, walking programmes and hands-on care. Surgery may be an option if symptoms are severe and are not improving, and this is a shared decision with a specialist.
Is walking good for spinal stenosis?
Yes, for most people. Walking in shorter bouts with rests, and gradually building up, helps maintain fitness and confidence. Cycling is a useful alternative if walking is limited.
