Muscle Spasm
"I&#039;ve tried most of the muscle relaxers - flexeril (cannot tolerate), skelaxa (unfortunately cannot tolerate) and Robaxin (not quite strong enough) for a tight and unrelenting  piriformis.  5mg of good old fashioned Valium takes care of it in the evening. Too bad it&#039;s sedating otherwise it would be my go to med during the day for this tight muscle - that despite loads of PT, massage and stretching I am unable to get to let go. I really appreciate Valium for this!"
