A woman I know had her tubes tied after her second child was born. She said she had horrible abdominal pain and gas after the procedure, even a few weeks later. I think she said the doctor said it was scar tissue or something, and had to go back in and make a repair of some kind.
She eventually recovered, but said if she had known the pain would be so severe, she would have stayed on birth control and taken her chances with pregnancy. That’s kind of extreme, I guess, but she said the pain was just that bad.
