** Thanks for contacting with your health concern 1. Since the symptoms are there for the last 3 months and still no physician or specialist opinion is taken thus presently the case for me is unexplained abdominal pain since upper abdomen too has right quadrant, left quadrant and central which consists of different abdominal organs with different pathologies like biliary colic, pancreatitis, aortic aneurysm, reflux disease, gastritis, dyspepsia, splenic infarction [the pain radiates from front to back] PS. have an appointment with a general surgeon or with your Cardiologist to exclude any surgical or heart issue with detailed history, clinical examination and relevant investigations 2. since diabetes is uncontrolled, it could be diabetic gastroparesis or chronic mesenteric ischemia [since atherosclerosis is 2-4 times more common with diabetes and affect all major arteries including aorta] and if there is atherosclerotic obstruction of the celiac artery and its branches it might result in constant intestinal hypoperfusion causing abdominal angina. PS. one has to exclude diabetic ketoacidosis or hyperglycemic hyperosmolar state for any metabolic disturbances
