Only the foot on the side of my TKR. Actually I have numbness that is not nearly as strong up past my knee. At times this “nerve pain” is bad enough that I have to get up and “walk it out”, so to speak. Hard to discribe also I feel the night following surgery onto my surgical side, causing bruising from the top of my leg to the foot. My surgeon was very unhelpful. Didn’t even want to do X-rays. But the nurses insisted. Never really heard anything about them. My experience was unusual and not typical but I will never have my other knee done. Both knees hurt. So it didn’t work out for me. And doctors are not all the same.
