I have been on pretty much every sketeal muscle relaxant in the pharamcy. recently i have developed muscle spasams along with nerve pain a i was perscribed zanaflex.. it took the edge off but no releif.. since i have used most sketal muscle relaxants.. should i CNS relaxants liek valium or somthing?? also sleeping is impossible.. my aunt was perscribed it after she had her c-4 vertebre fused and said she had great success.. i am skeptical but desperate.. I am young too so i am not sure how to ask my pain management doctors about switching medications without him questioning my condition? anyone else have a problem like this? thank you!
