a couple of months ago my friend tackled me to the ground and i felt a pang of pain in my ribs. i blew it of but i had a fitness test 2 days later. i could hradly breath. i early fainted but then i was told to sit out the rest of the class. it had subsided for a bit but then it grew in pain even if i was lying on my back it would send stabs of pain. i had a second fitness test and the same thing happend. so do u think its bruised, brroken or cracked?
