I have had bad heartburn for two months and yellowish diarreha for about six weeks. Other symp are headaches, nausea, burping up vomit, right side minor tenderness below rib cage, gas, get upset stomach about 20 minutes after eating. Diarreha-poop floats and has a foul smell. I have also seen one yellow soft pea size object filled with tiny white beads every so often. Any ideas about what this all might be?
