Suggest Medication For Pain In Middle Of Chest And Diarrhea

The past few days when I eat I get diarrhea. Between yesterday and today I have been able to keep certain foods in but I m also experiencing a lot of burping and some pains in the middle of my chest. Tried antacid but that hasn t helped. I haven t had a lot Of energy and I feel a lot better laying in bed. What could be wrong with me?
