Thank you for the query.
Pain after a meal usually appears with peptic ulcer
, gallstones or pancreas disease. And so are vomiting and nausea. Peptic ulcer gives upper middle abdominal pain
, sometimes chest burning, acid reflux
. Gallstones and pancreas usually gives pain in right upper abdomen radiating to the back.
It is advisable for you to have some diagnostics. You should start with abdominal ultrasound
, full blood work, liver tests (AST,ALT,GGTP), amylase, bilirubin, urine analysis. Upper GI endoscopy is also advisable.
Hope this will help.
