Pain below the kneecap?

If you are young- under 20- you probably have Osgood Schlauter Desease. I have this. I am a soccer player, a swimmer, a runner- I'm doing sports all of the time. When I was around 11 years old, I got this pain in my knee that is EXACTLY like the one you described. My knee was sometimes a little swollen under the kneecap and you could notice a small lump there- but that's not in every case. Don't worry. Osgood Schlauter is a common desease in young people that is untreatable. The doctors can diagnose it, but the only thing that really helps is pain meds. Their is no treatment. It doesn't hurt that often- you're right. It would still help to go to the hospital and ask to order an X-ray just to be sure. Osgood Schlauter can be seen on the X-rays. Another thing that I've found that helps- if you do end up having Osgood Schlauter, is an oil that can be bought at the drug store. It's called "WELDA Anrica Massage Oil" and it really helps sore muscles. It comes in a small green bottle with an orange label and a white cap if you need to find it. If you have Osgood Schlauter, don't worry. It's not a big deal, the pain isn't bad after a while, and the desease goes away when you're over the age of 18.
