Most people with spinal stenosis foramen causing impingement cannot walk for a long period of time without pain. This upon the nerve and radiating is called claudication. More serious symptom include symptoms in the arms or legs. difficulty controlling bowel or bladder function, or poor The “sciatica” is a more balance when walking. generic term used for cases where the pain radiates into the leg in the sciatic nerve distribution.
