I had an ultrasound today and the tech had a hard time finding my gallbladder-I'm not sure if she did actually see it or not. I am going to have a hida scan this Friday.I was wondering if anyone had anymore info on this test and how lengthy it was.I also have looked up a lot of info regarding gallbladder flushes and if I do have Gallstones I definitely want to try this before considering surgery. Any suggestions about which flush is most effective?
