My doctors had trouble finding medicine for my muscle tremors pain and spasms. I have multiple sclerosis and Ankylosis spondylosis (rheumatoid arthritis) and am only 25 years old. Flexeril and soma was tried as well as skelaxin however finally I was placed on valium. I thought it was strange being as I have always known it as an anti-ankiety medication, but it works wonders in allowing my muscles to relax and ease. It does not take away everything every day but about four days a week I have very little pain. I hope this may help.
