I have abdominal and lower back pain, get very hot and nauseated late at night. Can tolerate food in small quantity only. I have a VERY large hiatal hernia and my gallbladder was removed over 3 years ago. I also have a mild fever.The color of my urine and stool are of a normal color, as of two days ago my blood work does not show pancreatitis  nor does the sonogram which was done at the same time, my face is yellowish but not my eyes. I am afraid to eat and fear I may have pancreatic cancer. I would appreciate your opinion. Thank you.
