Spinal stenosis: symptoms, treatment and what to expect

The short version: spinal stenosis is a narrowing of the space around the nerves in your spine, usually in the lower back. The classic sign is leg pain, heaviness or tingling that builds when you walk or stand and eases when you sit or lean forward. It usually changes slowly, and most people manage it well. Exercise and physiotherapy come first in NHS treatment.
What spinal stenosis is
Your spine has tunnels running through it that carry the spinal cord and nerves. Spinal stenosis means those tunnels have narrowed, leaving the nerves less room. It's most common in the lower back, called lumbar stenosis. It can also happen in the neck, called cervical stenosis. NHS inform describes the changes behind it as a normal part of ageing, which is why it's more common as people get older.
Spinal stenosis symptoms
Lower back (lumbar)
Pain, aching, cramping, heaviness, weakness, tingling, pins and needles or numbness in your legs.
Neck (cervical)
Pain, stiffness, weakness, tingling, pins and needles or numbness in your arms, and sometimes headaches.
The giveaway is the pattern. Lumbar stenosis symptoms get worse when you walk or stand, and ease when you sit down or lean forward. That pattern is one of the things a physio looks for when working out whether leg pain is coming from stenosis or from something else, such as sciatica from a slipped disc.
What causes it
- age-related changes in the spine, the most common cause
- an injury to the spine
- rheumatoid arthritis
- some bone diseases
- being born with a narrower spinal canal
Does spinal stenosis get worse?
This is the question most people are really asking. NHS inform says any progression is usually slow, that the nerves can adapt, and that most people manage their symptoms well with the right guidance. NHS guidance doesn't describe a fixed set of "final stages". The rare serious problems come from severe compression of the nerves or spinal cord, and they have clear warning signs, listed at the bottom of this page.
How it's diagnosed
A GP or physiotherapist asks about your symptoms and examines you. Scans are usually kept for symptoms that are severe or getting worse.
Spinal stenosis treatment, in the NHS order
- 1
Exercise and physiotherapy
First on the NHS inform list. The goal is to keep you walking and standing comfortably for longer, with a plan built around what brings your symptoms on.
- 2
Lifestyle changes
Staying active, pacing yourself, adjusting activities that bring it on, keeping a healthy weight, stopping smoking and managing stress.
- 3
Pain relief
Medication, heat or ice. A pharmacist or GP can tell you what's safe for you.
- 4
Spinal injections
An option if symptoms aren't controlled.
- 5
Surgery
For some people whose symptoms stay severe despite other treatment.
- 6
Specialist pain services
Longer-term support for pain that's hard to manage.

Spinal stenosis questions
Can spinal stenosis kill you?
Spinal stenosis itself isn't described as life-threatening. NHS inform says any progression is usually slow and most people manage their symptoms well. The rare emergencies are severe nerve or spinal cord compression, which is why the warning signs on this page matter.
What are the final stages of spinal stenosis?
There isn't a set path of stages that everyone goes through. For most people symptoms change slowly, if at all, and the nerves can adapt. If walking, balance or bladder and bowel control start to change, that needs checking urgently rather than waiting.
What is the best painkiller for spinal stenosis?
There isn't one best painkiller for everyone. NHS inform lists medication as one part of managing pain, alongside heat, ice and staying active. A pharmacist or GP can tell you what's safe with your other health conditions and medicines.
Is walking good for spinal stenosis?
Staying active is part of NHS advice, even though walking can bring the leg symptoms on. The trick is pacing: shorter walks with rests, building up gradually, rather than stopping altogether. A physio can help you find a level you can build on.
What is cervical spinal stenosis?
It's the same narrowing in your neck instead of your lower back. It can cause pain, stiffness, weakness, tingling or numbness in your arms, and sometimes headaches.
