Hi, my name is Ruby. This is my first time posting and on this site. My doctor thinks that I might be in the beginning stage of RSD. But the nerve doctor says that I don't have all of the signs of RSD. I fell and brused my knee about 5 months ago and the pain is not getting any better. It hurts to set in a chair, to have anything touch my knee above and below my knee, from my knee down to my toes swell up, and my foot is cold about 95% of the time, and it hurts to walk. But I don't have any discolor in my leg, and my leg muscle is a little smaller, but my doctor says that I'm not doing my leg exercises. I don't do them much because it hurts too much. If anyone can help me figure this out i would really be thankful.
