I had my gallbladder removed in Feb 2019. No stones or sludge either. However my HIDA scan replicated my symptoms. I had what the general surgeon said they've been seeing more of and that is a "high functioning" gallbladder causing just as much pain and issues as a low functioning. I went ahead and had it removed. It took several months just like you to find a "new normal." It seemed I trucked along in my new normal for a few years and then in 2022, I began having severe GI issues. Labs revealed H. Pylori. Fast forward, I've seen 2 GI's, had every test known to man, been treated twice for H. Pylori and even did 2 weeks on an antibiotic for SIBO as this most recent GI's ditch effort to treat my phantom illness. I've been told it's in my head as well. By 2 different docs. I don't know how long I can go on trying to function like a regular human feeling like I do. I have tried everything you can imagine from cutting certain foods out, intermittent fasting, cutting out alcohol, you name it. There is no pattern. I'm miserable. It seems there's a space for people like you and I and the medical world doesn't recognize it. I am running out of options here. So sorry for your suffering. Know you're not alone.
