Had left TKR done around 4pm Thursday. I had multiple reactions from the anesthesia: Low blood pressure, low body temp (93) and severe nausea. I finally started to stabilize Friday afternoon. I really didn't have much pain around the surgery site, but I did notice the top of my left foot was numb and swollen. I never experienced this numbness with my right TKR (6 years ago).The pain level is really kind of odd ( not that I'm complaining!!) , but I've gone over 8 hours without taking anything and this is only day 3 post op. Is this numbness something I should be concerned about? My leg doesn't feel numb, just the top of my foot...is this why i'm not feeling much pain? Thanks!
