Took a while, but I finally made the decision to undergo a total knee replacement (TKR) on my left knee. Went in Tuesday afternoon and was discharged a few hours ago. What really caught me off guard was how much pain there is when the nerve blocks wore off . . . WOW!!!!!! Even though you are kept fairly drugged up, there ain't no way to block it all. That first day post op was pure agony. I know I made the right decision, sure didn't feel like it then. Anyone one else here been thru one? Would like to know how you dealt with it (they sent me home oxycodone, a muscle relaxant and a blood thinner).
