PHILADELPHIA (CBS) – If you are one of the tens of thousands of adults with knee pain you know that it is a very common problem. But what about knee pain in children?

Sure, it is easy to diagnose after an injury in a young person but when there’s no trauma, we often think about infection as one of the possibilities. We also think of a problem called Osgood–Schlatter.

As children grow and develop, their knees grow and they’re actually more prone to having problems with their knees if they grow very rapidly. They can go through a period during adolescence where they have pain when they’re running or playing sports, and it can be quite problematic.

If you have any questions, a visit to your doctor is a great idea.
