Not that its going to do any good but suck it up coonman. Do what your told and listen to the Drs, nurses, and physcial therapists. This isn't their first rodeo, its yours. They don't care about your whining boo hooing and belly aching around. Reading this I'm afraid of you getting infection, not realizing it, and hesitating going back to get it looked at. Get your butt up and put in the work you are supposed to. Follow up like you are supposed to. If you don't and it goes badly its your own fault, no one elses. You are out and already admit that theres no pain for gosh sake. Have you been icing it for the swelling? Are you doing what they told you to do as far as ice and working it out?

Go read trapperkecks post about his buddy that had a stroke. I guarantee he'd trade places with you. He's got a harder road ahead than you and more uncertain.

You better do what the doc told you or you could lose the leg.
If you get an infection and you dont go in to the hospital they may amputate.

But then the knee wouldn't hurt again.

Seriously Dave, listen to the doctor and do what he says. This surgery could be a great thing or a horrible thing, depending on how you take care of yourself. I've seen folks ignore the doctor and end up with less mobility, I'd hate to see that happen to you.
