Spinal stenosis is a medical condition where the spinal canal narrows and pinches the spinal cord and nerves, usually due to disc herniation or a tumour.This may affect the cervical spine, the lumbar spine or both, and results in low back pain as well as pain or abnormal sensations in the legs.

A stenosis is an abnormal narrowing in a blood vessel or other tubular organ or structure.
