WHAT CAUSES A GALLBLADDER ATTACK The pain can come from a stone making its way down the biliary duct or bile tube toward the duodenum of the small intestine. It can also be caused by a back up of bile in the gallbladder (with or without stones) that causes it to swell from fullness causing discomfort.
