i would not worry about pancreatitis y friend,,,i too have the sae issues somewhat,,,and thought years of being a weekend warrior had "done me in"!!
but what i got going on is gerd,,,,its basicly acid reflux but with more symptoms.
i get the pain just under the lowest ribs,it extends into my back,,,,stuff like that too.
thought it was gallbladder maby too,but it all checked out alright.
one other thing you might look into is sphincter of oddi disfunction.
i will tell you this,,,i by chance also have a friend who DOES have chronic pancreatitis,we went through the apprenticeship together....well,he got REALLLLLLLL sick,,,,,and found out he had pancreatitis brought on by heavy alcohol use.
i will tell you,,,he was 200 lbs strong,and it ate him away to 130 lbs!!!
he cannot eat hardly without causing attacks!,,,,his docs have told him it looks pretty bad,and hes got about 3-5 years left9hes had it about 7 years already)
...if you had pancreatitis,,,you would be in LOT WORSE SHAPE THEN YOU ARE.
so get that out of your head or youll make yourself worse feeling thinking about it!!!
also,,,chronic pancreatitis is just that,,,chronic,,and ongoing,it only gets worse,and will continue to over the course it takes,,so i doubt thats your issue,and thats A GOOD THING.
