Spinal stenosis is a narrowing of the spinal canal. The spinal canal is located in the backbone. It is a small space that holds the nerve roots and spinal cord. If this space becomes smaller, it can squeeze the nerves and the spinal cord. This causes pain and other symptoms. Stenosis can occur anywhere along the spinal cord. It is most common in the low back (lumbar) region.

Factors that increase your chance of spinal stenosis include:
Your doctor will ask about your symptoms and medical history. A physical exam will be done.
Tests may include:
Special exercises can help stabilize the spinal cord. Exercise can increase muscle endurance and mobility of the spine. This can relieve some pain. Sometimes exercises are ineffective against spinal stenosis.
Wearing a corset or lumbar brace can help stabilize the spine. This may relieve pain.
Surgery is reserved for severe cases.
