You say a couple of inches to the right of your belly button. Is that diagonally up or down from the belly button?
Diagonally up would be the funny loop where the ascending colon meets the transverse colon. I have problems with that spot. As long as I avoid certain foods, onion, wheat, etc, it's not too bad, but it still flares up even when I haven't had any of these products. I've been living with it since January 2009 and the doctors have basically given up too. They say it's a food intolerance, but we can't work out exactly what food is causing it.
