Bruised rib...?

In the state of mind where: its crazy.

MAN. i have this rib bone that hurts whenever i move around, or slightly when i just stand up. its driving me crazy !
all from today my teacher told the class to do exercises and when i turned round i heard a poppopopopopopop..
i just had to say that. its driving me crazy. i think i should go x-ray it just incase :S
like penny from - so you think you can dance....
or maybe just put some ointment thing on and see what happens ?

today at school was okay. the rib thing made things sllloooowwwwwwwowowow.
