Forgive me if this has already been discussed somewhere -but I can't find a way to search this site to check...

Has anyone heard of a link between people that have an autoimmune disease (like diabetes, chronic fatigue syndrome, hypoactive thyroid disease, celiac disease, rheumatoid arthritis, MS, etc) and CRPS? I've heard that there might be a genetic factor with CRPS, but was wondering about an autoimmune factor that would predispose or increase the likely hood of having CRPS triggered?
