Thank you for the query.
Such liver tests and amylase level indicate some irritation caused by fatty foods, spicy foods, alcohol or even medicines. But it does not seem to be the reason of abdominal pain
If your pain is in the upper middle abdomen, peptic ulcer
can be the reason. And it can not be visualized in the ultrasound
. Such pain usually appears after some time of the meal. Nausea can be present.
I suggest you to have gastroscopy done as a next step.
If you are over the age of 50, colonoscopy
should be also done.
Hope this will help.
