Hi Sandy..
So sory to hear of your problems.. I think if I were you I would start taking ALOT of grapeseed extract.. go high on the antioxadents that inflamation is comming from somewhere, and stay away from Ice.
I have heard of RSD without the disabling pain the rest of the symptoms tend to be the same but without the pain *sigh* so you should not dismiss RSD out of hand because if thhis is what is going on you are in a timeframe to put it into remission or cure it if it is sympatheticly induced swelling.

Good luck in your search for answers and I hope you find yr answers soon,
Hugs,
Sandra
