Hi Rita,I also had the Hida Scan. Are you having a Hida Scan with CCK? If you are, then that is what I had and instead of ingesting fatty food, they put CCK into your IV which simulates the effects of a fatty meal. The technician warned me that if a person does have gallbladder problems then when the CCK is put into your IV (towards the end of the test), this can cause major pain (like a gallbladder attack). It caused no pain in me and it turned out my gallbladder was fine.But, I did have one problem with this test. They injected so much liquid in me with the IV that I had to urinate so badly during this test that I thought I'd explode (and I am not one of those people who tends to have to pee all the time). I begged them to let me run to the restroom but they would not allow it as it would've forfeited the test results. So, I held it but I will never forget the last 1/2 hr. I thought I'd wet my pants!!!Stacey
