3 yrs ago I injured my right knee as time went on I was DX with RSD (Reflex Sympathetic Dystrophy) it is mostly in my right Knee/feet. About a wk ago my knee/leg and foot started to really bother me more than usual with walking and within no time my right knee,leg and foot started swelling pretty good. The outside of my ankle is so swollen you can't even feel my ankle bone. and on top of my foot red blotches are forming all along the outer right side of my foot. The back of my leg there is only one area that is painful to the touch and I'd say it was about 4 inches above my ankle. The burning is getting worst of course I don't know if this is part of my RSD of if this could be a blood clot...I won't be seeing my dr til thursday!! anyone can help..thank you..

Turned out to be Elphant's Foot, just another issue to deal with RSD
