I was diagnosed with atypical RSD about 5 yrs. ago after have thumb reconstruction surgery. I ve been okay and able to deal with it. However, about two weeks ago my skin started itchy all over my body. I feel the itchiness, don t touch the area (after seeing what scratching can do to your skin), and notice the area that feels itchy is fiery red. If I don t scratch it, it eventually goes away and starts to itch and get red somewhere else on my body. Could this be related to the RSD?
