comfrey ointment? It helps with sub-cu injuries and promotes ligament and tendon tissue healing while minimizing the pain... a co-op or the like might have some. I make it myself and use it when needed for rotator cuff problems. You just can't use it every day long term. You can use it for a few days then take a break from it for a few and alternate. Try it, it could rescue you from the doctor and help you get back on your feet quicker than you thought. If you can't find any, PM me and I'll give you a couple recipes.
At any rate, I hope it goes away fast.
Take care, nadinbrzezinski!
Everything just going on like normal in other daily activities and then all of a sudden, for no apparent, or unusual, reason whatsoever, BOOM! pain!!! 
I hope your knee gets better fast!
One thing that helped my knee problem last fall was arnica gel. It also helped when I fell and landed on the fingers of my left hand in December. Very good for bumps, bruises and swelling, but should not be used on cuts or scrapes.
Our supermarket (Giant in Maryland) started selling Boiron's Arnicare recently, but if it's not available in your local supermarkets, try Vitamin Shoppe or GNC.
