Hi, I can only tell you a little of my experiences. I had an ultrasound last year that showed a normal gb. It was "normal" because there were no calcified stones. Cholesterol stones will not show on ultrasound. A week later a HIDA scan showed my gb was working at <1% function. When my gb was removed a month later it was full of adhesions and scar tissue. My assumption is that I had a liver full of cholesterol stones and they blocked any flow of bile to the gb. I was running a chronic low grade temperature at the time, 101 degrees all the time and felt like crap. I thought if my gb was removed I would be fine. I was wrong. I continued to have pain, indigestion, diarrhea and all of the gb symptoms. I finally got the nerve to flush and have gotten out over a thousand stones in 6 flushes. See my other postings for details. Please flush and take care of your gb. You will feel so much better to take charge of your own health.
