Do you mean a outpatient pain clinic - or a residential type clinic?
We have a thread on residential types-

For the outpatient type - I think some on the RSD forum go to special Pain Dr -and possibly some on the chronic pain and spinal forums.
Basically they take over the Rxing of meds for severe and long term pain.
