whats wrong with my hand?

uh yea, i post this here cuz this forum seems to have the smartest people, doctors etc. yea so yesterday i punched somthing pretty hard and today if i bend my hand backwards its hurts, like a sharp pain in my hand. deosn't hurt if i press on it anywhere or bend it anyother way. tell me its not broken. i know u would porbably need xray to tell, but is it possible to just like bruise somthing that would cause this type of pain? thanks

You probably did`t broke any bone, if you do it would hurt you when you punched. Maybe you just streched ligament or something. Do you have any swelling?

like orto says probably ligament damage. maybe due to hyperextension of the wrist.

i guess there is a possibility you have a hairline fracture. to be sure i'd have it x-rayed.
