Lumbar Spinal Stenosis

By wp_zaman

Back aches and pains are a health concern for millions of people. Nearly 29 million Americans saw their doctors because of back and low back pain in 2002. There may be many reasons for backaches and pains. One cause could be spinal stenosis.

Stenosis means narrowing. In spinal stenosis, the spinal canal, which contains and protects the spinal cord and nerve roots, narrows and pinches the spinal cord and nerves. The result is low back pain as well as pain in the legs. Stenosis may pinch the nerves that control muscle power and sensation in the legs.
