From time to time I will randomly get very bad back spasms. I will just be doing anything random from running, grappling, jumping,(mostly things that involve vertical shock on the back), and I will get a shooting pain up my lower and middle back. Sometimes, like a muscle cramp, if I can feel it coming on ahead of time, I can stretch really quick and work it out before it hits. But when it does hit hard, I will be nearly imobilized for about a week or two. Sometimes I can barely sit down or stand up, and even have trouble getting to sleep because the pain is so bad. However, in between these random occurences I usually go full effort at whatever activity I'm doing and feel great...it hits me like a sniper. Wondering if anyone else has had this problem, and if so, what have been the best ways to prevent it or heal it if it does occur? I take ibuprofin, use a heating pad, and try to stetch and pop my back, but what else is there to do?
