Last Thursday I had my second knee replacement. I came out of hospital on Sunday. I now have a very bruised and swollen knee. My husband puts a sleeve of iced water around it 3 times a day to reduce the swelling. It seems to be going on alright. The only think is the last 2 days I have felt very nauseous and have absolutely no appetite. I hope it is the cocktail of drugs still in my body and will feel better again tomorrow. What with strong painkillers, morphine based, paracetamol. Epidural drugs etc I suppose it takes a few days to get them out of my system.
