has a web site you might want to look at- Piedmont Phyical Medicine-and read what he says about RSD and also the section on meds. He helped turn my life around and has people from across the country and world come to him. Having said that he in NOT for everyone. He believes the vascular system plays a role in RSD. Please believe me, this is only FYI. I have nothing in this except wanting to share information that was helpful to me. Carose
