Formed by an opening at the back of each vertebra, the spinal canal is the passageway through which the spinal cord passes. Spinal stenosis can occur in three locations in the spinal canal: in the middle of the canal, in the lateral recess (where the nerve roots run in the spinal canal), or in the neuroforamen (where the nerve exits the spine).
In some instances, symptoms of spinal canal stenosis may require simple monitoring. When symptomatic, spinal canal stenosis is often treated with non-surgical treatments like exercise, activity modification, pain medications, and epidural injections. If the symptoms persist following these treatments, a surgical opinion is typically warranted for the spinal canal stenosis.
