Here is a list of doctors who've been recommended by CRPS patients over the past year. It was compiled on another FB group which specifically focused on recommending good providers. Recommendations came from around the US and around the world. This should be very helpful.
These are all English-speaking countries. Hoping that this will start the ball rolling elsewhere :)
