I am so sorry that this has happened. Try not to stress too much until you actually get to meet and work with this new doctor (goodness knows the last thing we need is stress on top of everything else). If he is knowledgeable about RSD then you shouldn't have to worry about him doing anything to aggravate the pain and cause a flare (one would hope anyway). Make sure to tell him your fears, be open and honest with him, and see how things go.

My first pain management doctor who initially diagnosed the RSD had a poor bedside manner and often made me angry...but he was a good doctor and in the end what he brought out was my stubborn streak and determination to fight. This is something that I can see in hind sight...but didn't appreciate until he left the practice and stopped seeing patients and I was forced to switch. Now I'm with a compassionate doctor like the one you say is leaving you. She's offering essentially the same treatment as I got with the first one (PT and meds) but when I leave her office I always feel at peace and optimistic as opposed to stubborn and determined. The results are the same and neither one ever did anything to aggravate the RSD...the biggest difference is just how I feel coming out of the appointments.

I hope things work out with your new doctor.
