Punched my car window with my fist?

Well yesterday one girl pissed me off and last night I punched my side window with my fist..I punched it 3 times and after that it the window broke, my hand hurt a bit but it wasn't nothing serious, and now when I woke up, it's hurts a little bit more, and it's kinda swollen so should I put ice on it or something, I don't think it's broken, but after all I'm not a doctor so I don't know. Any advice? Thank you
