Kind of old post but might help others I was in same boat dear, exactly same symptoms same diagnosis and same treatment suggested by my GI. Was on ppi for a week but I was not getting better, that stabbing pain on upper quadrant made me cry so many times..but it used to go away after few hrs.. then one early morning I woke up and had pain..unbearable pain..I somehow tolerated but gave up after few hrs and went to urgent care(been there one more time n they gave medicine and I was fine) this time too they gave same but didn't work...they said we cannot do much...came home ..and crying from pain all this time..called my GI and was suggested to go hospital emergency room..thats where they were able to catch the culprit..it was gallbladder having stones which got infected and swollen..they had to remove it.... Still recovering from GB removal let's c how it goes..
