hi i had gone through your query and understand your concerns. i would come up with two most possibilities to fit your condition .these include
1.first possibility is,CHOLELITHIASIS;formation of stones within the
gallbladder.
2.second possibility is,APD ACID PEPSIC
DYSPEPSIA .
possible causes include;
-irregular dietary habits,
-modern lifestyles (drinking,
smoking,etc),
-EXCESSIVE USE OF PAIN KILLERS,ANTIBIOTICS,
STEROIDS for even minor complaints,
-CURRY,HURRY, and NIGHT WATCHING,
-SUPPRESSED STRONG EMOTIONS are the main causative factors.
I hope this is helpful for you, thank you
