A week ago I had a very bad case of heartburn and burning stomach pain. The only thing that would ease the burning was alka seltzer. After two days the pain moved to my lower left belly. Its like something I ate was moving around. Well the pain has moved in my lower left belly and stayed there. The doctor took exays and found an infected area of my colon with diverticulosis and prescribed antibiotics. My question is, what burned in my stomach so badly and then moved to my intestine and stayed?
