You have to worry about a small stone in the ducts leading to the pancreas, or in the pancrease as well.
The test for this is MRCP, or ERCP.
ERCP is done on scope.
MRCP is like an MRI which can reveal the stones.
They will not show up on other testing consistently.
That is assuming your amylase is high. That is not clear as you have not included reference ranges.
However, this is an often missed scenario.
Your symptoms are more consistent with gastritis.
OK, so that is an initial answer….
