blame it on being a reckless teenager but imo if it doesn't hurt that bad don't worry about it, at this point all they'll do is put brace on it anyways, and obviously if it is broken its not too bad and the drs can't do anything anyways, just get a splint or brace or something from like cvs or something that looks like it would help, or if you think its a bruise you could get by with an ace bandage i think
