WOT a load of rubbish some docs dish out. I have FM, and a good friend of mine has RSD, and I can tell you that we're on different pain planets. RSD is a whole different level of pain and suffering and body damage than FM, because RSD affects different body systems (orthopedic, limbic, language, blood pressure, dystonia etcccc) whereas FM can be utter misery but it doesn't spiral into, well, you know... HELL!
