Hello You seem to have Cholelithiasis (Gall stone ) with gall stone induced pancreatitis. Please meet a gastroenterologist at the earliest who would advise you correctly what to do. What next to be done depends on the general condition, whether you have active infection, whether a stone is lodged in bile duct among other parmeters. He may suggest for ERCP also , which is a advanced endoscopic procedure if required.
