I thought my leg was bad. It turns colors, like a greyish blue but does not stay that way. It gets real cold but that does not stay that way either. This will get you though. The hair on my right leg grows way quicker and way thicker than on my left leg. One of my doctors that I see told me it was due to the RSD. Of course the veins in my lower leg and foot are awfull ugly now since all his has been happening to me. I am glad I at least do not have a rash like some of you. I feel sorry for you. I have the weakness, the burning sickening pain that stops you in you tracks.
