Even if you don't have all the characteristics of RSD doesn't mean you dont have it right? The only thing I don't really have is the discoloration. Sometimes my arm is completely pale sometimes it looks like a corpse. Other times it looks just normal but get red blotchy rash looking thing, or turns purple but mostly right around my wrist. But I have the constant pain, my swelling isn't constant so much anymore, the palm of my hand sweats really bad, and is very tender to the touch, and its usually really cold compared to my left arm. I've only been diagnosed with RSD since April but have had all these symptoms since the day after my injury happened. But the occupational therapist that I had seen said that I don't have the coloring of RSD.
