I have the same trouble. My foot swells whenever I'm sitting up or on it. I have half the range of motion in my foot now. I walk like zombie because of a limp. I try so hard with PT to get it back. My therapist has told me she's at the point there's no more she can do for me. It's all me now. I still can't do anything though, the only relief I get is when my leg has been propped up on the couch. That's how I usually am to avoid the agonizing pain. The real down side is I never really go out. I have zero exercise because I cant. I used to be fit and active now I'm fat. Ugh... i'm talking to my doctor about a neurostimulator. What about your treatments?
