Spinal Stenosis is a medical condition where the spaces within the spine narrow, putting pressure on the spinal cord and nerves. This narrowing can occur in various parts of the spine, including the neck and lower back, and may lead to pain, numbness, or weakness in the arms or legs. The condition can be caused by age-related changes, such as arthritis, or by injuries and congenital factors. Symptoms often worsen with activity and improve with rest. Treatment options include physical therapy, medications, and in some cases, surgery to relieve pressure on the affected nerves.
