I would be that RSD guy, and here's my doctor at U.S.C., of whom I think the world:

Steven Richeimer, M.D.
Chief of Pain Medicine, Keck School of Medicine
University of Southern California
Director, U.S.C. Pain Management Center
1520 San Pablo Street, Suite 3450
Los Angeles CA 90033
323-442-6202
323-442-6255 (fax)

Not exactly geographically convenient from the South Bay, I grant you, but I found that coming initially from Santa Monica with mid to late morning appointments the traffic was never very bad. (But avoid late afternoon appointments at all costs.)
