Kris, good luck to you. Sounds like you are having all the right tests. I have full body rsd. So hang in there. No more ice. you have been given some really good advice here. try to relax the best you can til you find out what is going on- stress agrevates every disorder - I am sure you are aware of that- but if it is RSD- stress really causes problems- so really try to relax.
You must keep the pain level down in case it is rsd- it spreads when you have pain. Take care and keep us posted. CZ
