Probably best to go to a doctor, you don't want it to heal wrong cause then they will need to break them to set them right again. And will want to know why you didnt come earlier. Just make up an excuse. Fell of the stairs. Broke them playing soccer/hockey/basketball... Tripped over something....
And maybe consider telling someone you trust about the abuse...
And you may want to post about it in the health forum too?
maybe i'm late replying, anyway, just some ideas
Keep us uptodate ok?
