Thank you for your response. I thought it is the same mother, who also responds on lever flush forum. Anyhow, I am somewhat scared about this procedure, since there are negative reporting also of the possibility of stones being stuck in the bile duct, thereby, leading a person to an emergency room. Alhamdulillah, I have no pain though ultra sound shows some stones in gb, which is causing some gas problems. I hope someone will guide me properly on this subject.
