I am close friends with a person with advanced CRPS and she has been very happy with Dr. Getson in NJ (suburbs of Philadelphia PA) because he listens carefully, and is very gentle (even uses a head lamp so patients can lie down in a dark room during the exam!). He used to practice with Dr. Schwartzmann at Drexel.
Dr Philip Getson 100 Brick Road, Suite 206 Marlton, NJ 08053

interesting site I ran across: "Personally Recommended RSD Doctors" (I can't vouch for this personally)
