Three Months Of Having Diarrhea Two Or More Times A

three months of having diarrhea two or more times a week, stomach pain, rings under eyes, one week I had fever and was nauseated but after that week the diarrhea continued to this day .. upper GI scope normal , blood and ultrasound showed possible inflamed pancreas so I cut fat out of diet but still have diarrhea some times three or more times a week...what other possibilities could it be...I'm so tired and can't leave my home because of it.
