I have pain in the lower area, some of the pain starts high, just under the chest area, center. If you press on it, there is no pain. No Blood, but I do hear the stomach making noise. I eat a very high protein diet. work out hard daily. My stomach feels in large most of the time. But after a week or two, it goes away, my abs show, then the process starts all over again. The blatter area is where most of the pain is.
