I had my gall bladder taken out in 2010 & haven't had a single problem since then valerie. One of the nurses in the emergency ward a few weeks earlier told me that she'd had no problems after hers was removed either, and that reassured me a lot.
Experienced the pain badly on & off after meals for about 3 months beforehand. It was excruciating a few times & I had to be taken in an ambulance to hospital to get a couple of doses of morphine. The first time I thought that my years of drinking in my 20s & 30s had caught up to me & my liver had burst. Seriously - I thought I was going to die.
My mother rolled her eyes when I told her how bad the pain was (apparently, only women can experience real pain - men are just moaners). Then she was talking about it to her friends at the volunteer shop, and one lady told her that she'd had her gall bladder removed too, and she told Mum that the pain of gallstones was much worse than childbirth. My pain attacks were taken a little more seriously after that conversation.
Modern medicine is amazing. I had my gall bladder removed late in the morning, and that night, in the hospital bed, I ate chicken breast & steamed vegetables for dinner, and I was discharged the next morning. My whole time in hospital for the operation was approximately 24 hours (and I had an umbilical hernia repaired at the same time, so I had extra holes in my belly). Though, unlike you valerie, I was able to get all of my tests & scans done in the weeks beforehand.
Anyway, relax & take it easy for a while. At least laparoscopic surgery takes a lot less time to recover from than the old, more invasive, surgical methods.
