Ooooo, galbladder attacks are horrible!
Just about anything can cause the stones to move. Activity can certainly shake them up– found out about mine while taking martial arts classes. Sometimes, though, they just happen out of the blue. Anything that shakes them up will potentially have influence, but that’s not the sole cause. Passing gallstones is fairly rare, and they can get stuck.
Have you scheduled surgery yet to have your gallbladder out? They can do it through a fairly tiny incision; you’re in and out on the same day, back to non-strenuous usual activities inside a week.
