Hi CRPSed!
I have had RSD/CRPS for a little more than 22 years now. This has to be the first time I have ever heard of someone not having any pain from it...after all, it is a "pain" syndrome. I know everyone is different in the symptoms they have, but generally pain is a common factor. CRPS 1 is usually caused from an injury and the pain is worse than the initial injury and continues even after the initial injury has healed.

How do they know the SGB's actually worked or helped you when there was no pain to be relieved?

I am not saying you do not have CRPS, I am no doctor! But I would question that diagnosis further. Like you, I would not want to be taking meds and getting SGB's for something I didn't have! This might be a very stupid question, but did they rule out any other nerve conditions?

Wishing you the best!
