you haven't mentioned your age? are you experiencing some nausea vomiting
worsened with eating. abdominal pain
? are you an alcholic? if you are above 40 i would suggest you to go for a ultrasound
which can show a inflammed pancreas if that is the case.you can also go for blood amylase test which gets increased 4 folds in pancreatitis
.i would also suggest an ecg done.
