Okay so today me and my friend where running outside and i fell over a curb and scratched up my knees, hand and hip pretty badly, but now (Like 6 hours later) i can't even move my left knee without a pain going down my calf. like i CAN move it but it just hurts like a B!t*h if I do. and when ever i walk on it it has the same pain. it hurts a little more then when i sprained my arm. so what do you think is wrong? A fracture? a break? (I doubt it, but you never know) A sprain? should i go to the doctor? Hospital (I hate hospitals but- you gota do what you gota do)
THANK YOU!

PS~ the main pain starts right under my kneecap. Also i am a 14 year old girl Petite girl, if that helps at all.
