I agree with Surgeon in his comments that gall bladder or pancreas are certainly possibilities. Other causes can include an ulcer, inflammation of the stomach or esophagus, or GERD.
Tests to evaluate this would be blood tests (to evaluate the pancreas), an abdominal ultrasound (to evaluate the gall bladder), or upper GI series/upper endoscopy (to evaluate the stomach, esophagus and small bowel for any inflammation or ulcers).
Followup with your personal physician is essential.

Happy holidays,

there are several possibilites; gallbladder disease is certainly near the top of the list. Chronic pancreatitis, which can be due to alcoholism, is also a possibility. The only way to find out is to see your doctor and have some tests done. No online diagnosis can be very accurate, especially with no lab or other data to evaluate.
