I have had a mri, ultra sound, scope and colonoscopy.   Gastro Dr says it is scar tissue due to my gallbladder.  Used to happen after I eat but now its all the time.  Have no appetite.  Sharp pain in back on left side. Weight loss over the last 2 years. Said no pancreatitis.   I am scared he is over looking pancreatitis cancer.  Had this for a couple of years now.  Had many tests.  Had gallbladder out.  Had the blood work for my pancreatitis and mri and was unremarkable last month 1/17.
