I also was diagnosed with CP, did 47 days of Prednisone and have an MRI scheduled for April to see if it shrunk the benign mass on the head of my pancreas. According to my GI, after all my other testing, if the mass shows improvement...this confirms an autoimmune diagnosis. Trying to determine what caused the mass has been difficult as my GI is not forthcoming with alot of information or in answering my questions. The diagnosis is important because it determines treatment and if the body can attack the pancreas, it could also attack other organs as well. Good luck to you and hope you get answers and feel better soon.
