Hi. Thanks for your query. Noted the history and understood your concerns. Vomiting and stomach pain recurring after a year in a young girl of your age might have been due to acidity problems like gastritis, GERD. I would advise you the following as your tests are normal, although you have not mentioned the tests hence get the remaining tests done out of the ones I am mentioning below: Upper GI Endoscopy. X-ray of the abdomen in standing position. Ultrasonography of the abdomen. Tests of stool and blood. Get started with a PPI like Omeprazole. Domperidone in a dosage as per your Doctor s prescription at 8 hourly duration. Antacids every three hourly. No stress and/or anxiety is very important. Soft bland diet. Get n opinion of a Gastroenterologist or a General surgeon once the tests are done for clinical evaluation, correlation with the reports and proper diagnosis and management.
