When a co-worker had gallbladder surgery last year, she had a tough time. She was off work for about three weeks. She had terrible pain and nausea. Her doctor said he wasn't sure why she was having such pain, that the surgery was uncomplicated and there wasn't anything suspicious to see. He said he thought there might have been some scar tissue from a surgery she had many years ago, and it might have pulled loose.
She's fine now, but she had an awful time after her surgery. It was probably six weeks before she was able to go back to work full time, which is very unusual for a laparoscopic procedure.
