Hi, Lately I have experienced pain during sleeping hours at my diaphragm. I ve had endoscopy to and through the stomach in the last 12 months - all good. I have also had periodic pain on rare ocasiones in same area for decades. Stress seems to be contributory although little theses days - retired. Night meals high in fat possibly contributory recently. No known food allergies, but suspect gluten and I are not best friends. Nor are high fat meals as mentioned. Healthy, 63, no meds, male, white, active, plays guitar and actually takes long walks on the beach ;-)
