Thank you for the best wishes! I had a good surgery (TKR of my right knee). I was surprised at how much pain I had,even in the recovery room. I stayed only one night in the hospital. I have a lot of swelling in the leg, need some advice on how often and how far I should be trying to walk, using a walker. The swelling is impeding me, I think. I saw a photo of swelling on another post , with three different levels of swelling; mine is definitely similar to the first leg. So swollen that my leg feels hard to the touch.
