I often fear with a new pain or symptom brushing it off as rsd and it not be. Part of the reason why I went to over 40 eye apts and have had so many diagnostic tests for my legs. It is a hard call to know what to do.For some new symptoms I try to wait a few days but again that can be risky if it were not RSD. I am not on pain meds other then like neurontin type but i have heard people mention that their meds mask a pain of condition that was not RSD. It really shows how painful this condition is. For me I seem extra senstivie even on non rsd areas. I think cause I am so protective of my body that all my body parts are not used to certain movements. Are you monitored regularly for this? Have you discussed your fears with your doctor and does he know about rsd? I know you would think he would but not always have I found that the case. Hang in there and I am sorry for your other health conditions on top of this
