I landed on my ribs sometime back and it hurt to laugh. I don't think I broke one, but maybe cracked one? Hate to think about broken ribs.
In contrast, one of our dogs had a broken pelvis and 3 broken legs when we got her. Having her checked out kind of slipped everyone's mind. Turns out that the pelvis and one of her legs never healed. She is the happiest dog ever. I also envy the fact that dogs don't get sinus infections.
