Hi! I had one - it was not painful - it was like an ultrasound; Oh, I am referring to a HIDA scan - Did you intentionally write "HILDA" scan? the HIDA procedure is easy but it does not detect the gall stones consisting of cholesterol. They said they could find none but after four flushes, there were easily more than 500!

it wasn't bad at all for me....but I had it AFTER I did the parasite and liver cleanse. The doctor DID inform me that I would have the same symptoms during the procedure that I would have eating a high-fat meal.

I'm the one that didn't have gallstones, but gallpolyps. It was just as painful as gallstones, believe me.

For the Hydascan, they inject a radioactive material into your bloodstream and you get to watch it go through your body. It glows on the screen.

I believe they want to see if it will even make it through the gallbladder. Mine did and I was fine. 100% perfect!! AFTER all the cleanses.
