I've suffered 4 gallstone attacks in the last three months, and suffered through them. Three weeks ago I went to the hospital with another gallstone attack. An ultrasound revealed a stone 1.9 centimeters. Apparently it was unable to pass through. Since then I've eaten a low fat diet and had no further attacks. I am about to do Huilda Clark's gallbladder/liver flush, but am worried. What if 1.9 centimeters is too big to pass, even with the help of Epsom Salts ? I don't want to have it become lodged in the duct, too far in to fall back into the gall bladder. The pain is intolerable and I'm afraid surgery will be the only option then. Does anyone have any advice? Has anyone passed a stone as large as 1.9 centimeters?
