Spinal Stenosis

One cause of back pain is spinal stenosis. Stenosis means abnormal narrowing. The spinal canal contains and protects the spinal nerve roots. In spinal stenosis, the spinal canal narrows and pinches the spinal cord and nerves. This causes low back pain and pain in the legs. Stenosis may pinch the nerves that control muscles and sensation in the legs. This leads to pain and abnormal feelings in the leg muscles and areas supplied by those nerves.

Spinal stenosis often happens to people as they get older and arthritic boney growths occur in their spinal canal. There is also a loss of the disk height between the bones of the back, which also adds to this problem. Sometimes the problem is present at birth.
