I had a TKR 4 weeks ago and have recovered extremely well. However today , I was walking when all of a sudden I felt a bit faint and my leg felt a bit numb . I sat down and the numbness went , I had no pain and it hasn't swollen at all. Can anyone tell me if they have experienced this and iv so what it is. I don't know whether to go to the hospital Orr whether it's just scar tissue breaking down ???
