Spinal Stenosis Definition

Spinal stenosis is a condition in which the spinal cord or spinal nerve roots are compressed or choked. Spinal stenosis is related to degeneration in the spine and often results when a bone spur or herniated disc compresses the nerve roots exiting the vertebral canal. Sciatica is the most common symptom of spinal stenosis. Sciatica is pain, tingling, weakness, or numbness that radiates into the rear and legs. Most cases will produce pain into the legs with walking, and the pain will be relieved with sitting. Pain caused by spinal stenosis can be treated conservatively with anti-inflammatory medications, epidural injections, or exercise emphasizing flexion. In severe cases of spinal stenosis, decompression surgery may be necessary to relieve back pain.
