I had my gall bladder removed in 2002 and 2 weeks later I had the same pain in my upper abdomen but 10 times worse. I called 911 because I was on the road and had to pull over. I could barely talk the pain was so bad. These attacks have happened numerous times over the years and every doctor had a different reason. Acid reflux, IBS, and the list goes on. I have had a scope done 3 times and they haven’t found anything – even biopsies of my stomach. It seems to come on when I take any kind of opiate pain killer too. So then the docs said that I was allergic to opium. That hasn’t made life any easier. I’m in pain but pain killers cause more pain. Ususally I will throw up after the attacks are over and they last usually around 30 – 45 minutes. If anyone can help me out I’d be ever so thankful. I’m tired of docs looking at me like I’m nuts. Thanks, and I hope your pain gets better
