I had my gallbladder out in 1999 and it was the best thing I ever did. I had the surgery on a Friday, and I was back to work on Wed. The moment I woke up, I felt better. The surgeon told me I had a tumor on my gallbladder and that it should have been taken out years ago. And all of my sonograms tests came back with "small gallstones, no surgery needed."
After the surgery, I was sore, couldn't bend. I only had a little reaction to the gas. When they do the surgery, they "blow" up your abdomen with a gas, so it is accessable. I felt some of those "gas" pains for the first day. I was on the pain killers for only two days. It just depends on the person. Oh, by the way, I had the laser surgery.
I was 25 when I had my son and I had terrible gallbladder pain during my whole pregnancy. I had my gallbladder out when I was 28.
The only problems I have now are reflux, some diahria and I watch my spicy and fatty food intake. Those are manageable.
Good Luck on your surgery, you'll be glad you did it!
