I just got back from an ultrasound with a double hourglass shaped gallbladder. Inflammation below the fibrous wall is 7mm thick, with a group of stones in the lumen. I come back often with pain in the right side. The pain has been dull for many days. The doctor advises me that I have an hourglass-shaped double-bottom gallbladder with dull pain in the right flank, do I need surgery?
