The majority of people with spinal stenosis are unable to walk very far at any one time, according to MedlinePlus. The legs are often painful, weak or numb. Sitting down or leaning forward tends to relieve the pain.
Additional symptoms of spinal stenosis are poor balance, urinary incontinence and lack of bowel control, MedlinePlus explains. Pain, numbness or cramping sometimes shows up in the lower body, back, neck or arms. Spinal stenosis occurs when the spinal column narrows, which puts pressure on the spinal cord. The condition also appears when spinal nerve openings shrink. The condition has several possible causes, including arthritis, bone disease, spinal birth defect, herniated or slipped disc, and spinal tumor.
