I am alwaqys having problems with spasm and twitching muscles in my back and gi tract. I have used things like levsin and levbid for the problems and really haven't noticed to much of and improvement from this drugs. The probelms is really getting bad with my back muscles and it is starting to cause more pain. It is usually always followd by my ibs-c acting up. Has anyone tried any kind of other muscle relaxers that have helped.
