My wife is diabetic and has chronic gastritis. She has this acute pain on the upper abdomen and the pain can only be relieved by pathidine. The doctors have prescribed Hyoscine,omeprazole,amoxycilline,ranitidine and promethazine but nothing seems to help as the pain keeps on coming back. Endoscopy was done and it came out negative, no inflammation of the stomach lining, no ulcer. Please help as we have spent a lot of money on medical bills and nothing seems to improve.
