I'm curious f you have laprascopic surgery, because I've read that this is somewhat of a common problem because surgeons can sometimes not fully close you, or nick another organ. I still have pain where my GB was. I actually had an attack about a month after my GB was removed! They never tell you those things before they rip your organs out. I have read that sometimes stones can form in the nub/stump left from the GB, or liver stones
can travel to that spot and get stuck. Another issue may be that you just aren't producing enough bile. That's my theory, anyway. I drink Peppermint leaf tea when I start feeling the pain, and it generally helps, because it enduces bile production.
