In my case it was diagnosed by Carnett's test and treated with trigger point injections. Works pretty well, but where my gall bladder was still just never seems to get completely better. It is usually from abdominal surgery. I had 2 c-sections, multiple endoscopes, EUS, and so many ERCP's, and then splanic nerve ablation, gallbladder removed, and cervical branch ablations.

I honestly don't know. There is not a blood test. She was diagnosed at Mayo Scottsdale, and there were lots of tests. She was also diagnosed with POTS and Ehlers Danlos. Those three disorders tend to go together. I think it is ruling out other things, looking at history, and making the connections to the other disorders.
