Spinal Stenosis

Spinal stenosis is the narrowing of the open spaces within your spine, which can put pressure on your spinal cord and the nerves that travel through the spine. It is most commonly caused by wear-and-tear changes in the spine related to aging.

It most often occurs in the neck and lower back. In the neck, narrowing in the upper spine can cause numbness, weakness or tingling in a leg, foot, arm or hand. Compressed nerves in the lower spine can cause pain or cramping in the legs when standing for long periods of time, or when you walk.

Anesthetic injections, or nerve blocks, near the affected area or corticosteroid injections into the outermost membranes covering the spine and nerve roots can be used to alleviate the inflammation and acute pain that radiates from spinal stenosis.
