Chronic RUQ pain
It’s going to be tough finding someone who even believes what you have is real. No laparoscopy is required. I inject people with some lidocaine at the point of maximal pain and see what happens. If they like the way they feel with the lidocaine, I inject them with phenol 6%, about 2-3cc. Works about 80% of the time. Some pain management guys will do this. They may even be able to see the nerve in question with a high resolution ultrasound, but no promises on that.
