Hi im 12 years old and about 2 months ago, i tripped while going up my stairs while sprinting and my knees hit head on with the stairs. The top sector of my knee. Ever since it has not hurt unless i push really knotty, but its gotten more frail and there is also a ball of what im guessing is cartilage that i can move around adjectives across my knee with my finger, and its really scary. So what should I do and what is wrong?

I Cant Go To Sleep!!?

You should definitely diary a Doctor's visit to let a professional check it out. It will giveyou some peace of mind and also if it is something that desires attention, it's best to take care of it sooner than after that on when it could possibly become worse. Good Luck and hope everything works out for the best!
