During routine abdominal checkup I found multiple sludge stones in gallbladder. I got pain near right rib after eating non veg.sometimes I get sharp pain which comes and goes but not very severe.I have not taken any medication for pain till now as pain is not severe and comes rarely once or twice in a month. Should I go for surgery or wait And I have small doubt does having gallstones raise LDL cholesterol? If yes should go for surgery urgently and how many does it for discharge after operation
