Thank you for the query.
Pain under the sternum can be due to peptic ulcers or stomach inflammation
. Usually it does not give any changes in laboratory tests and it is invisible in the ultrasound
. The best way to have it checked is upper GI endoscopy
with Helicabacter Pylori test.
duct dilation should be investigated with abdominal CT, as ultrasound is not a good way to visualize pancreas. You should also visit gastroenterologist and consider ERCP procedure which will clear the situation with pancreas ducts.
should be also checked with heart condition, and at least heart ECG should be done.
Hope this will help.
