Assuming that pancreatitis is pretty similar in people to when dogs and cats get it (I work with animals not people, lol), it's when your pancreas is inflamed and the digestive enzymes it makes start activating while still in your pancreas, essentially trying to digest the pancreas itself. I can only imagine how painful that would be. When we treat animals with pancreatitis we withhold all food and oral liquids and put them on a drip, usually for days, and sometimes even longer. The pancreas basically needs a total break from making digestive enzymes for it to be able to recover.

I would definitely head to the hospital because I would imagine that treatment would be pretty similar and that you should be on a drip (to maintain hydration and electrolyte levels) and that you shouldn't even be attempting to eat or drink anything. Plus a nice addition of pain meds to the drip would be a nice addition I'm sure!

I hope you are feeling better soon!!!
