I do not have this...my really severe pain is more of a bone crushing sort of pain. My muscle pains generally seem to be more related to poor movement as the result of my RSD. I have noticed I seem to be more prone to muscle strains since my RSD went full body...but I don't think that's what you're talking about. I also get sever muscle cramps that do things like cause my hands/fingers to claw up. It could very possibly be Fibromyalgia or another autoimmune disease. Have you talked to your drs about this? It's definitely worth getting checked out since it could be something easily (or more easily) treated than the RSD.

Right now I have a dr who thinks I also have peripheral neuropathy...so it's absolutle possible that you have more than one thing going on. I hope you find relief from this soon and answers. Wish I could help more.
