question: I developed incredible pain on my left side approximately mid way on my rib cage about 2 oclock this afternoon.  I dont remember any sudden pain like I cracked a rib or anything. It  seems very localized and intense.  I did go bowling yesterday for the first time in a long time and I lift a lot at work.  I have to take about 6-8 advil to get any relief and hurts to the touch.  Any suggestions as to what it could be?
