Hello Thank you for asking question. I am Dr Adil Abdominal pain has number of causes. By stomach pain, i presume that you mean pain in epigastric region, that is center of the upper abdomen. Epigastric pain also has number of causes. If i see a patient who has epigastric pain for such a long time. I would order baseline tests that is, blood cp, liver and renal function test and more importantly an uper GI endoscopy and abdominal ultrasound and will also look for H-pylori antibodies to completely rule out some common causes. The above mentioned test should be done and the reports of these tests will aid in making a comment and final decision. I hope you have understood my point. You may ask me more questions anytime. If you have already done these tests, feel free to share their reports. Regards. Dr Adil
