Oh, I'm so sorry to hear that you have a bad back too...! I know ALL about it, he he ! The only thing that could take muscle-pain away, was a treatment at the ostheopat. Does this exist is the USA too? I'm sure it does! It is much better for you than chiropractor! I wasn't even allowed to go to a chiropractor!! Try ostheopathy! It isn't cheap, but it's worth a try, hey!
Good luck
