I had soft yellow stools for 2 weeks back in May/June, a couple weeks normal, and then yellow stools which have turned to diarrhea for the past four weeks. No pain except a little in my lower back, on my right side, for a couple of days, but it has resolved. I also have had a low-grade fever, between 99.1 and 99.9, for at least a month. And I have mild nausea when I wake up (I am not pregnant). I had three tests, one for E. coli, one for salmonella and one for white blood cells. All were normal. Also the blood test, for thyroid and something else I forget. I keep reading about pancreatitis. What is the likelihood? What else could it be?
