Spinal Stenosis


Spinal stenosis is a narrowing of the spinal canal. The spinal canal is located in the backbone. It is a small space that holds the nerve roots and spinal cord. If this space becomes smaller, it can squeeze the nerves and the spinal cord. This causes pain and other symptoms. Stenosis can occur anywhere along the spinal cord. It is most common in the low back (lumbar) region.
