An Introduction to Spinal Stenosis Signs and Symptoms
The space within the spinal canal may narrow without producing any
spinal stenosis symptoms. However, if narrowing places pressure on the spinal cord, cauda equina, or nerve roots, there may be a slow start and progression of symptoms.
Common Symptoms of Spinal Stenosis
Spinal stenosis symptoms may cause the neck or back to hurt. In most cases, people with symptoms will experience:
- Numbness
- Weakness
- Cramping
- General pain in the arms or legs
- Foot problems.
If the narrowed space within the spine is pushing on the sciatic nerve root, people with symptoms of spinal stenosis may feel radiating pain down the leg (a condition called sciatica). Sitting down or flexing the lower back should relieve these symptoms. The flexed position "opens up" the spinal column, enlarging the spaces between vertebrae at the back of the spine. In order to relieve
back pain, flexing exercises are often advised, along with stretching and strengthening exercises.

Severe Spinal Stenosis Symptoms
People with severe symptoms of spinal stenosis may have problems with bowel and bladder function in addition to foot disorders. For example, cauda equina syndrome is a severe, rare form of spinal stenosis that occurs due to compression of the cauda equina. Symptoms of cauda equina syndrome may include:
- Loss of bowel and bladder control
- Problems having sex
- Pain, weakness, or loss of feeling in one or both legs.
If you have any of these more serious spinal stenosis symptoms, you should call your healthcare provider right away.
