Hi, my father is 55 years old and has unexplained abdominal pain from last 3 months. We did every test complete blood test, endoscopy, colonoscopy, ultrasound, Fibroscan but no conclusion came. He got diagonal with Diabetes and since then he is on diabetes medication. But pain remained same. Only medicine that gave a bit relief was "Corbal-G". He takes this capsule once a day at night and with this he is around 90% ok but still occasionally feels the pain. We don't know what the reason could be. Please give us some direction as what should we do and which specialist should we consult. I have attached pictures of medicine he is currently taking and his initial tests. Thank you
