Hello. Thank you for posting.
Spinal stenosis in your lower back (lumbar spine) can cause pain or cramping in your legs when you stand for long periods of time or when you walk. The discomfort usually eases if you bend forward or sit down, but it comes back when you stand upright. For example: As you walk through the grocery store, does leaning forward on the grocery cart reduce your pain? Pain that eases when you bend forward is typical of lumbar spinal stenosis.
Other symptoms of lumbar spinal stenosis besides pain may include numbness, weakness, or tingling in the leg or foot. In severe cases of lumbar spinal stenosis, nerves to the bladder or bowel may be compressed, which can lead to partial or complete incontinence.
