gallbladder/vsg/pain

Hi everyone, I have a question that isn't directly about WLS. I has the VSG 4 years ago and lost 90 lbs and gained about 40 back. Around that time i started having horrible pain in my back everytime i ate. I thought it was because of the surgery. However ,it was my gallbladder. I have since had my gallbladder remove. Now i am having pain exactly where I used to have my gallbladder pain. The pain is duller and not as frequent but it does happen when i eat. Can this still be because of my gallbladder? Or what do you thi k it could be? Thanks for any comments in advance

you can still have gall stones with no gallbladder. maybe that's it?

I had the same problem .... My surgeon did an ERCP and I had bile sludge in my ducts.
