there is acutally a clinical study being done right now about how rsd effects the sympathic systen including BP HR etc... i know that there is alot of us with this same problem and meds do make this worse. but the passing out is a problem and i think klb that you should give your doctor a call as there could be something else goin on. i know that there was a thread about not blaming rsd for everything and this is a good cause for getting it checked out ....
