I have bulging discs at L4 L5 and stenosis caused by a ligament, but the reports all say mild. However, I have pain that increases if I sit very much. Sometimes the pain goes down the back of my butt and if I am in the car for any length of time, it goes all the way to my ankle. When I wake up in the morning, my back is so tight and stiff, and if I do the piriformis stretch, I can gradually loosen it up and the pain eases some. I also think that my pelvis is crooked and one leg shorter by about 1/4 inch and things are just out of alignment. I think my muscles cause most of my pain.
