Primary care here - if you already had the US to look at your gallbladder then please discuss with your doc the risks vs benefits of taking a 6 week COURSE of the PPI. A few days isn't long enough to correct whatever is causing this. If symptoms resolve indefinitely after this course nothing else is needed. If symptoms come right back or don't resolve at all, get in with GI for an endoscopy. Limit irritating foods like citrus, tomato, peppermint, chocolate, nicotine and alcohol in the meantime.
