Is that med a muscle relaxer? I would call and make an apt with your treating doctor since you have new symptoms. I take sometime for my tight calves/legs zanaflex that is suppose to help muscles relax and sleep. Right now I am not sure if it helps sometimes I think yes and sometimes no. As for botox that would be a no for me. Everyone is different but I have read you never inject the rsd area and for me a finger hurts so a needle oh my. Does your doctor deal with rsd a lot?
