Cervical Spinal Stenosis

Spinal stenosis is a condition, mostly in adults 50 and older, in which your spinal canal starts to narrow. This can cause pain and other problems.

Your spine is made up of a series of connected bones (or “vertebrae”) and shock-absorbing discs. It protects your spinal cord, a key part of the central nervous system that connects the brain to the body. The cord rests in the canal formed by your vertebrae.
