I've had CRPS for almost 4 years now. It started in my left leg and has traveled up my leg. Now I'm feeling the same kind of pain starting in my right leg. Can it be spreading even though it's not having the horrible swelling or the color changes?? The swelling in my left foot and leg isn't like it was, it went down after the 2nd year. My right leg is swollen some. I didn't injure it, but I use a knee walker, using only my right leg. I haven't really walked in almost 4 years. At first I thought it was just tired and overworked. Now with the pain being almost constant, I'm getting worried. I don't really want to try to get into my doctor if there isn't even a possibility that it might be a spread...I'm only wondering if it can be a spread without all the symptoms or not...
