It sounds a lot like my story. It's going on for two months now (great summer!) I've been to many doctors, 5 pain clinics and no one can stop the spasm in my back. What I did find that works, is 10 MG of Valium and 2 Tylenol 8 hour arthritis pills at least for a while. I got a third shot yesterday (Prednisone?) and I might just be working, but won't know until the spasm stops for a few days. Same with my PT, so I quit that! Doesn't it sound like something that could be remedied easily??? And I have no idea what brings it on!
