Yes, everything I've read about pancreatitis says you do have a terrible stomach ache followed by throwing up bile. Usually the pain is either in the middle of the stomach or toward the upper left side. It could be either chronic or could've been an acute attack. You should get an ultrasound and a CT scan just to be sure. I've been going through the same thing for weeks now, having terrible stomach aches followed by a painful sensation in the upper left side of my stomach, with nausea but no vomiting. Ask your doctor to order some tests. Good luck.
