Is it normal for my knee to hurt under the kneecap?

I am in dance and We have to do this move that I think I threw to hard. I woke up the next morning to feel a sharp pain that I couldn't rub out becasue it felt like my bone was covering it. It only hurts when I bend it so i can walk fine but not to aggresively or the pain flares. Is it a pulled tendon or something, I need help!
