Keep it elevated and isolated for a few days. It will heal fast. When you sleep, prop a couple or few pillows under it. For pain, I would use Excedrin back and body pain reliever. Keep icing it as often as you can. The swelling will go away afeter a few days. Best of luck. I have had 3 knee surgeries and I know what it's like. Feel free to PM me anytime. What procedure did you have done?
ice and then heat. advil or something over the counter for pain, bengay rub, have your leg propped up, do not stand for to long, Maybe the doctor can give you samples since some will if they have them around,
