I've been there, and I know exactly what the pain from pancreatitis feels like. I had a second attack of it several years after the first. The therapy for that is to pour fluids through you intravenously and not otherwise feed you. In my case I was up to pee every four hours round the clock. Both times for 3-4 days. The second time I was in the hospital they convinced me that since this was the second attack of pancreatitis I should have my gall bladder removed. I was against it but the hospitalist said "Oh pooh, it's like your appendix, you don't need it."
The gall bladder removal was a snap - it was done laparospically on a Monday morning, and the next morning I was driving home.
So all in all, I wouldn't worry all that much. Knowing what the problem is and the normal outcome should help. Feel free to ask any questions....
