I had my gall bladder removed in 2000, I also got the type of surgery that just leaves the tiny scars. In a day I was up and moving around, not painfull at all. I found out I had them when I was pregnant while getting an ultrasound, I never had any pain or attacks so I had no idea I had them.
The doctor removed them about 3 months after I had my baby, he said that my gallstone was the size of a golf ball.
My doctor said you have to remove the gallbladder if you are getting stones it is not working right and if the stones are removed, they most likely will return.
Good luck and hope you feel better.
