It's been more active than before the fusion surgery, but not terrible like it was after the "botched" TKR back in 2009. If I am standing up too long (that's 15 minutes or more), my leg will turn that nasty reddish-purple color, so when that happens, I know I have to sit down and put my foot up asap. Luckily, it goes back to "normal" color within 10 minutes. Still having some hyper-sensitivity on my lower leg, especially when certain fabrics touch it, or i forget to shave every day! The leg hair feels like wire coming out! My foot hasn't gotten that cold/burning feeling in a few weeks, but that only happens after the leg turns color and only if I don't stop what I'm doing and get that leg UP!
