What Causes Stomach Pain And Nausea With History Of Pancreatitis?

Hi yes I started with getting sick going to the hospital for a couple of days they said I had pancreatitis it cleared up I had trouble eating most foods for quite awhile . Lost about 20 LBS after a month I have regained my apatite but I feel sick everyday not real bad but some stomach pain ,burning ,upset sometimes nostious. I have had a colonoscopy and a stomach scope, blood tests testing for bowl diseeses . I was checked for crones and checked my pancrease and I had CT scan ultra sound checked my liver. I don t have a gal bladder out for 5 yrs and appendix gone for 20 yrs. Anyway there seems to be no answer just thought I would ask if you had any ideas.f
