I m having severe pain just under my diaphragm, at the top part of my abdomen. I may have a hiatal hernia based on a snap I felt while turning over during the night a few weeks ago, but this pain is a new development. Now it hurts to eat, and my stomach is distended. I m burping, bloated, and had to take a dulcolax to have a bowel movement after having been constipated for three days. What should I do? Do any of these symptoms seem consistent with a hernia or does it sound like some sort of infection? If so, what is your advice?
