Hi and welcome to HCM. Thanks for the query.
The best soulution would be cholecystectomy
since these symptoms are sign of choleelithiasis and it wont passs spontaneouslky. also stone in neck can lead to cholecystitis
and then you ll need emergent surgery.so it is advisable to do laparosscopic cholecystectomy which is a routine today in most institutions and it will prevent future complications. second option is frequent follow up and ultrasound
check of gallbladder
. of course,considering your previous surgery there could be some digestional difficulties but still i think that gallbladder is a reason of your problems.
Wish you good health. Regards
