you need to go to gastroenterologist for a diagnosis if your current doctors can't diagnose you and if it's autoimmune disease you take steroids to lower the inflammation you can't treat this with herbs because the inflammation is out of control. Did you get these tests(igG4 levels) for autoimmune pancreatitis that are in this article? https://www.healthline.com/health/autoimmune-pancreatitis#when-to-seek-care "An older study from 2013 included 1,064 participants with autoimmune pancreatitis. It found that 99 percent of those with type 1 disease and 92 percent of those with type 2 disease went into remission with corticosteroid treatment. Symptoms that do not respond to corticosteroids can often suggest a misdiagnosis. Pancreatic cancer often presents in a similar way to autoimmune pancreatitis." so you need an accurate diagnosis to treat it and you want to rule out cancer of course
