Sorry you're in pain, Debbie. I had/have RSD and I know the pain, though I've been in remission 30 years. Seems miraculous to me.

I also have MS, with muscle spasms. I currently take Baclofen, but it totally messes with my head! I only take one 5mg at night. Doesn't always do much, but I need my brain! If I'm having bad back spasms, I'll take the baclofen and know that I am not going to get much work done, or I'll even stay home.

Aftermynap has suggested Zanaflex, and I've seen it mentioned many times here. People seem to prefer it and I'm going to ask my neuro about changing next time I go in.
