No gallbladder...still pain

I had my gallbladder removed in 1996 before I knew anything about flushes. Sorry that I let it happen now but hindsight is always 20/20

I have noticed since the surgery that after certain meals..an usually if I am very hungry, I get a pain just like the original gallbladder flare up pain in the center of my chest at the bottom of my ribcage.

Would a flush be beneficial for this? It comes and goes and I don't know why it happens. I don't want to cause more harm though seeing that I don't have the gallbladder anymore and wonder if it is leftover from the surgery (a stone that is landlocked somehow).
I have no idea how they remove a gallbladder so I picture a tube that connected to the gallbladder sewn up and a stone stuck there for life with no way out.

Thanks,
