What is 'lateral recess narrowing' in the back?

Lateral recess narrowing refers to a condition in the spine where the lateral recesses, the spaces on either side of the spinal canal where nerve roots exit, become constricted. This narrowing can result from various factors, including herniated discs, bone spurs, or degenerative changes in the spine. Symptoms may include pain, numbness, or weakness in the legs due to nerve compression. Treatment options often involve physical therapy, medications, or, in severe cases, surgical intervention.
