Hurts like crazy doesn't it. I strained my lower back a few months back hurt so bad i was taking perc's, muscle relaxers and naprocin and was in pt for a month. Still have to take the naprocin at times and do my exercise's with the ball and it really helps. A lot of my therapy is stretching and tightning the muscles in the legs which help's the back, does for me. Good luck and get better soon.
