The human body is weird, and wired funky. For example, I once had a severe gall stone attack. The gall bladder (which is what hurts) is located on the RH side of your abdomen kinda tucked under the ribs, next to the liver. I had severe pain in the front center of my stomach. Maybe 10 inches away from where it was being generated.
Also in an unrelated note, If I’d known where it was then, I’d have cut it out myself, cause it hurt that bad. It was the only time I’ve ever hurt so bad that I could only just lay there and moan about it.
