Well...I have to say that if your PT knows anything at all about RSD then they would know that there is no "textbook" RSD case. The exact effects and the way the symptoms present varies so much from person to person. Not that I'm saying to reject their opinion out of hand...I would probably follow up with your treating doctor about it and get their opinion (as alt said...you could have both). But seriously...for someone to have such specific ideas about how your RSD should present and on only the first visit...those would be red flags for me personally that they do not know what they are talking about (at least so far as the RSD goes). Might be an excellent PT but maybe should leave the RSD diagnosis to those who understand it better. I would still follow up on the tos though with your treating doctor just to be safe though.
