I have a large "bump" that pops out below my rib cage on the left side. I noticed it in August, but it was not painful then. I am now in constant discomfort. I am constantly "squishing" it when I slouch. It only "pops out" occasionally when I lay on my back. My boyfriend and I joke that it is my "free-range organ" or "loose riblet" but I am now concerned.
