My Knee on Tuesday - Day 4

I don't really know what is all right to do so that my knee heals well. The piece of paper said not to do heavy lifting, etc.  The attendant at the clinic said not to just sit with it propped up.  So I'm trying to move some. But it aches somewhat and has some swelling.  I have it up at the moment with ice on it.  Ice makes it feel better.
