Spinal stenosis is a narrowing of one or more areas in the spinal canal. This narrowing can put pressure on your spinal cord and/or on the nerves that branch out from the spinal cord. The stenosis is usually due to a combination of factors that included a bulging or disk herniation, arthritic bony changes, and/or hypertrophy (swelling) of spinal ligaments. Symptoms that are experienced typically are cramping, pain or numbness in your back and legs (if the stenosis is in the lower back), or cramping, pain or numbness in the neck, shoulders or arms (if the stenosis is in the neck).
Treatment options include medications, physical therapy or injections. The injection that is used typically to treat this condition is an epidural.
