Colleen, same here. I hope the MRI comes out OK. I know what it is like. In December, I starting having problems with my left knee and it got to the point that I couldn't even stand up on it much less walk on it. The orthopedic surgeon gave me a list of 4 things that I needed to do to ease the arthrosis, which they found in both knees.

1. Take Glucosamine with Chrondroitin each day
2. Take Naproxin as a pain reliever which also relieves the inflamation.
3. Work on an exercise bike with very little resistance and basically spin my wheels for 30-40 minutes 5 times a week. He said that what I have right now is bone touching bone and the spinning exercises will help keep my knees lubricated.
4. AND LOSE WEIGHT. He said that for every pound I lose, I will take somewhere between 6 and 8 pounds of pressure off my knees when I climb or go down stairs.

He said that if I do those things I will prolong the time in which that I will need to have surgery.

I still have pain in my knee, but it is just a minor annoyance, but not dibilitating.

I hope yours is nothing to severe and easily treatable.
