thanks everyone for been so kind and helpful. I'm going to go in to see my family doctor to see what he says about if I have RSD or not. At least my foot is not cold as mush as it was, my foot is hot and it swells up so my shoe cuts into my foot. My knee is starting to get cold now. I'm starting to get tingling in my leg, from the knee down to my foot. But I'm still walking on my leg with the help of pain meds and muscle relaxers. Wish me good luck for tomorrow. I see my knee specialist on Feb. 11. So I will see what she has to say then.
