Knees and Doctors

So I finally did it. Enough people have asked me when I was going to go to the doctor for my knee. For the past couple of months I have been limping around. It started off feeling like a pulled hamstring or tendon/ligament right at the connection with the knee. That lasted for a couple of weeks. Then it would just be stiff every time I sat for a bit. Slowly it seemed to get worse not better. I kind of knew it couldn't be something torn in there because it didn't really hurt until last week. So I bucked up and went to the doctor. Well nothing is torn. It all works the way it is suppose to. I got three x-rays and she said they don't show arthritis. But I have swelling which means fluid in the back of my knee, hence the stiffness and pain. So now I am on mega doses of ibuprofen for two weeks and I have a referral to a sports medicine doctor. If the pills don't work I am looking at the possibility of a cortisone shot........NOT.
