Does this sound like osgood-schlatter disease?

I'm 14 and for a little while now I've been having bad pain in my right knee whenever I run, jump, or like bend it like as in lunging. I get it in my left knee to but it's not as bad. My mom got me a knee brace for it but it doesn't help. I looked up the disease and it hurts where they say it does. Like below your knee like the top of your shin. I am very active. I do track volleyball I tumble and do cheerleading but is only invovled in cheerleading and tumbling right now. Only I was playing basketball earlier and when I was done my knee was really hurting bad. And btw, I never did anything to it, they jut randomly started to hurt
