I wonder if there is a doctor out there that is currently doing research on RSD that would be interested in testing us??? Perhaps there is a similar gene or enzyme or something we have in common. Seriously, my TMJ hurts more than my RSD does right now. It is the same side of my body as my RSD. I've mentioned that TWICE to my Pain doc......he doesn't think there is a connection......he says it is "stress".....but then again, HE was the one that wanted to implant me with a SCS just weeks after getting RSD to begin with. Where is the mood that says "bitter"???
