Well I've been resting it and icing the calf, it was not feeling any better. A few minutes ago I walked about 5' in my house and I felt a very painful "POP" in my calf. It hurt very bad. My wife has read that a blood clot in my calf could cause what I'm feeling? She wants me to go to the ER, but I'm not to keen on that idea. I feel like it has to be related to my TKR and the calf muscle must be strained? As for the calf stretch I was doing that until yesterday I read that it shouldn't be stretched, just iced and elevated? I don't mean to sound like a baby, I was just trying to see if this has happened to any of you after a TKR? Thanks all
