Hi benny1,Welcome to Healing Well! I don't have any medical expertise on the topic, but I can tell you that my husband gets very bad gallbladder attacks that sound an awfully lot like you're describing. Like you, his Hida scan showed nothing. Still, he gets repeated attacks, and even had a bad one today.
I wish that there was an easier way to deal with a recurrent gallbladder issue that doesn't appear diseased. I did hear of one instance where a PCP (mine) had a patient with severe gallbladder symptoms with nothing showing up on tests. Finally, the doctor convinced a surgeon to remove this supposed healthy gallbladder. Guess what? The gallbladder was diseased!
I hope you find answers to your questions!
Good luck,
Denise
