Hi. Thanks for your query. Noted the history of not getting relief from pain in abdomen even after taking medication and normal upper GI Endoscopy. Also noted that you are getting reflexes after eating something. Hence all this indicates that the problem is not in the gastric apart but can be an inflammatory lesion somewhere else. Hence I would advise you the following: CT scan of the abdomen. Tests of blood, urine and stool. Clinical evaluation by a General Surgeon and further tests as per the findings. Take a proper course of an antibiotic, metronidazole and such medicines as advised to get a complete relief. IF there is an indication of appendicitis or so, go for surgery.
