That's Fit

It's not something all that common among children, but would you believe it if someone told you 300,000 kids are affected by arthritis? The condition is mostly associated with elderly people, so it may be easy to scoff at the idea. But the Centers for Disease Control and Prevention have enough evidence to bring the "old person's disease" to the playground.

With one out of 250 kids suffering from some form of arthritis, it would be easy to imagine parents (or doctors) writing it off as a growing pain. In fact, estimates place the number of juvenile rheumatoid arthritis sufferers at upwards of 100,000. That is one of the worst forms of arthritis that can be crippling if left untreated.

Getting the right medication can make all the difference, just like it did with Breanne Watterson. Having suffered since the age of 4, her condition is mitigated so much that she can now perform like a normal teenager. It's rare, but her story shows how painful it can be to live with such a debilitating ailment at a young age.
