question: MY HUSBAND HAD DEVELOPED A BAD COUGH, AND FELT A SHARP PAIN ON HIS LEFT LOWER SIDE, THEN FELT A CLICK IN THE SAME SPACE, NOW HE HAS A HUGE BRUISE THE SIZE OF A BASKETBALL ON HIS LEFT TORSO ALMOST TO HIS STOMACH AND IS IN VERY MUCH PAIN. HE SAYS HE DID NOT FALL SO HOW COULD THIS HAVE HAPPENED, OR WHAT MAY HAVE HAPPENED?
