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,PEPTIC ULCER;upper gastro intestinal
endoscopy may confirm the diagnosis.
2.second possibility is,gas trouble (or APD ACID PEPSIC
DYSPEPSIA ).irregular dietary habits,modern lifestyles (drinking,
smoking,etc),EXCESSIVE USE OF PAIN KILLERS,ANTIBIOTICS,
STEROIDS for even minor complaints, CURRY,HURRY,,NIGHT WATCHING,SUPPRESSED STRONG EMOTIONS are the main causative factors.
treatment option;
without treating the underlying cause you cant be cured.
the underlying cause may be the STRONG FEELINGS such as WORRY,ANGER etc.have caused the inflammations they will not get better until these feelings have come out into the open.
I hope this is helpful for you, thank you
