Keep moving, lie on your side with a pillow between your legs, lose weight - if necessary, do Pilates often, go to Back 2 Basics for good treatment at Shad Thames. An ice pack is useful, but for no more than ten minutes or so. Alternate it with a warm pack. I had two burst - next to each other - about two months apart and was crippled. I really think about how I move, sit and sleep now.
