Tracie, I know that it is frustrating finding the right med and the root of the problem.Some muscle relaxers do not actually relax the muscles but are about the equivilant to taking something to cause you to get drowsy.I will give you a couple things that have helped me to think about.
Joint and inflammation pain,Celebrex,Mobic,MOTRIN
Nerve pain that makes fingers jump,spasms of the muscles,jolting pain to shoot through areas like your hands and fingers or feet.
I am doing well on a low dose of Topamax,
so instaed of a muscle relaxer,you might ask your Doctor about an anti-seizure med or a straight out pain med.
I hope you get the relief that you deserve.
