I have been having upper left abdominal pain for approx 12 yrs. It is a dull boring pain that lasts 1-3 days. An endoscopy 10 years ago indicated a mild hiatus hernia . I lost weight thereafter (27 to 25 BMI) and the pain went for 2-3 years before returning. I do note that pain starts 12-24 hrs after alcohol ingestion , and in the last 4 years has also occurred around my left kidney area as well (again 1-3 days). The pain is noticable more at night resulting in sleepless nights until 4-5am. The pain tends to be higher in the chest when lying and lower in the left belly, kidney and more usually in lower left rib cage area during the day. Anti-acids, heartburn are of limited use as are acid inhibitors. During the day I find that wind in my stomach area that is relieved by throwing back my left arm which makes me burp??? This gives a minute or so relief from the pain (more or less) Recent ultrasound, ct scan , have come negative as has the recent endoscopy (no hiatus hernia?). The doctors state they have ruled out pancreatitis based on negative CT scan. Is this correct, what other examinations would inform ??
