Hi, 6kiddos:

Generalized RSD is the technical term for full body RSD. There are two kinds of generalized RSD: external (which does not touch the internal organs) and internal (which does touch the internal organs). I have reached stage 3. Hopefully, I will never reach stage 4 because, like my anesthesiologist and pain management doctor said, stage 4 is equivalent to a "death sentence".

Thanks for being there, 6kiddos. I am really scared because it seems like my hypothyroidism came out of nowhere. I blame my generalized RSD for "attacking" my thyroid, the same way it "attacked" (or spread to) my lungs and gastro-intestinal tract. This is why I would have appreciated an answer to my original message to be absolutely sure RSD spread to my thyroid also.
