I busted ribs sailing once and it took a month before I could do anything without pain, I would definitely get a doc to take a look at it there is a lot of things for a broken rib to puncture, bruise, tear or lacerate. Even if nothing is wrong besides some swelling/bruising it will take down your level of concern and stress.

I'm off to surf for the weekend, they tell me it will be cold when I get back...I hate that.
