My husband once did that to his chin with a motorcycle handle bar. We didn't have a first aid kit handy so I stuffed a tampon in his chin to stop the bleeding. Once he got to the Yuma ER, his buddy had to leave the room when the Doctor pulled the tampon out and then proceeded to put his finger, up to the knuckle, way up in there to check for bone fragments! Cool stuff,huh?
So ladies just know this, tampons are sterile and can come in handy sometimes!
