question: For years I have had back pain, 4 years ago I had a lamenectomy on my L5-s1, and a discectomy on the disk below, aside from still always being in pain, and pain constantly shooting into my legs and toes, when I need to make a bowel movement the pain in my lower back on the right side increases almost to the point where I m in tears, and stays elevated pain until after the bowel movement. What could be causing this extra pain? Is it a sign another vertabrae has gone bad or pinching more nerves?
