Cwamit, your ribs are there to protect you fragile internals, like your lungs.

Go see a Doc, otherwise continual use or another bad landing may end up with a crack developing into a sharp rib bone into you lung area.

Other than that, there are couple of other area's that can have same feeling, one is the material between ribs that can get torn, Pace bowlers in cricket get it from the whip action in bowling, other is you have pinched a nerve in your back area and its inflamed.
But go see a Doc.... you wont regret it!!
