Pain is normal not only from the peg site but the fact that your stomach has shrunk, feeding through the peg delivers a certain amount of "food" in a relatively short period of time. Sometimes this can cause cramping particularly if you haven't eaten a reasonable amount over the last week or two. Maybe slow the pump or drip down, the problem with that is you are hooked up for a long time - that was one of the things I didn't like about the peg... hugs - hopefully you'll feel better soon.
