First of all I hear you when it comes to having pain and being told theirs
either nothing wrong or, we can't find anything. In your condition you
have to keep fighting for yourself and tell your doctors to get off the stick
and run more test. There are several options you can do.
Have they ran CT scans, rechecked you blood work did a Hida Scan, an
MRCP scan or any ERCP's to check your pancreas? These could all be
factors in your condition and test need to be ran to pin point the problem.
It took me over 2 years to get the right answers. But whatever you
do..Don't stop trying.
