hi welcome to HCM
-i had gone through your query and understand your concerns.
-basing on your complaints i would come up the possibility of ACID PEPSIC DYSPEPSIA
, may be the cause.
-sometimes the suppressed strong emotions like anger,worry etc have caused the inflammations and cause as a predisposing factor for the development of your condition.
-mediation are advisable for you
there is another possibility like PEPTIC ULCER;upper gastro intestinal endoscopy
may confirm the diagnosis
wishing you good health
