I had similar pain after my gallbladder surgery. Had exploratory surgery 5 years later and discovered that my duodenum had adhered between the lobes of my liver where the gallbladder used to be. They took down the adhesions, but I still had constant pain. A pain specialist diagnosed me with an abdominal neuroma and tried to treat it with ablation which helped for a few months at a time. After years of pain meds and ablation treatments, I finally got a neurostimulator that helped tremendously. I went from 7 different pain meds a day down to one. It took 25 years to get relief but now I’m doing well. Good luck and keep advocating for yourself.
