Hey, I had a HIDA scan several years ago and it was negative so they didn't think it was my gallbladder. Several months later I still was having the pain and was hospitalized for a week as I had lost so much weight because it hurt when I ate. Then another scan was done and they found I had a diseased gallbladder (no gallstones though) and when it was removed I was able to eat without hurting. This past year there's an upper abdominal burning sensation (not reflux and not inside stomach) and it doesn't matter what I eat, it even burns when I don't eat anything. I recently started taking Artichoke extract as I researched Functional Dyspepsia and maybe it will help. I will try anything. Best wishes to you.
