i have sever stomach pain just below my rib cage, as well as nausea (most of the time) and vomiting after meals. I have seen a doctor and she has prescribed somac, which made it worse when i took the medicine. Had an ultrasound for gallstones, and that was negative. the pain is really bad, and i am having trouble eating and going to work , as i feel sick all the time. any ideas? i am getting really worried.
