Tracy,
Sending you ((HUGE Gentle PAIN FREE HUGS))
Sorry to hear that you aren't doing well.
I get the horrible muscle spasms... Baclofen has helped with them and tremors, and I hear it's a good one for RSD, perhaps your doctor will try it. I take 30 mg of Baclofen daily, but was on Valium (which is old and not used much). I have the spasms so bad they lock my jaw... so what you are describing is NOT unusual.
I hope things brighten up soon!
