Did I Break A Rib? (Wakeboarders Would Know, Right?)

Thought that wakeboarders would be the best people I know to ask about this:

How do you know when you've broken a rib vs bruised a rib? One of those has definitely happened. What do I do to fix it, do I HAVE to go get an x-ray/see a dr, how long til it heals, and you know, anything else?

I didn't even get hurt wakeboarding! It was from forcing my big boobs into roller coaster harnesses all day! In Busch Gardens defense, the guy working Kumba DID tell me I could easily break a rib by doing that. Also, I aways have my hands up for the entire ride, so I am 100% using the harness to support me.
