That is an interesting question, sorry I don't have an answer. I know it is my gallbladder since the ultrasound showed I had a stone. But we have had a lot of people here who had their gallbladder removed and still had the same problems, because the liver was clogged up. They had to start flushing to feel better.

BTW after flushing all my symptoms went away though my 1 gallstone is still there, so it shows how important a clean liver is.

I don't think it even matters. Obviously any pain you're feeling means stones that need to come out. You just want them out and everything clean, regardless of what specific organ it's from.
