Lingering pain from knee injury. How to speed recovery?

I always try to put something warm on it. It relaxes the muscles and makes it feel nice..... :3 Er, anyways, try to take Advil and Tylenol together (works wonders for ANY kind of pain, I'll tell you THAT right there! xD) and just use it as little as possible. Trust me, I have BACK PAINS. They still return from when I mysteriously injured myself spelunking (caving). I always do that and it feels much better.
