Could I have Exocrine Pancreatic Insufficiency? My symptoms include chronic diarrhea (oily), pain in the abdominal area, nausea, and bloating. Also, I have had 4 or 5 episodes of extreme sweating (sweat dripping off my fingertips and soaking through all of my clothing), vomiting, severe diarrhea, sometimes, but not always, accompanied by pain in my abdomen that spread into my back.
