Mine showed up fine on the blood tests and the ultra sounds. No gallstones here.
I was lucky in that I know a few people that had serious gallbladder issues, and they said to push for the hida scan. The ultrasound found nothing for me either...just some "sludge" but they said it wasn't important. Doc was very surprised when the hida came back so low. It is twingy on and off so I'm sure it will eventually get painful enough to remove...I won't wait once I have one of those attacks! I feel bad you all had to go through so much pain with yours, that's awful.
