If you are in Ohio, or near Ohio, there is a Facebook group for RSDers. Lots of good info on doctors etc. several people, including myself, have been to various doctors at Clev. Clinic.
If you contact the RSDSA, Jim can give you the info on joining the FB group.
It is nearly 3 hours drive one way for me, and it is to painful and difficult for me, so I have stopped going. I am hoping to find someone closer to me.
The Occupational Therapy department was great to work with. The only place I have gone where they did not make me worse, and actually improved my range of motion.
