I found out I had gallstones the hard way after my 2nd ds. I passed one. Wow talk about hurt, I couldnt wait to get my gallbladder removed. I had laproscopic surgery also. It is a little painful after surgery but nothing that some good pain meds wont help out. Also this surgery is one that tend to make people very sick to their stomachs so ask for some meds before the surgery to help with that.
Good Luck!
