I get dizziness and the pain under my rib associated with flare ups as well. I always assumed that the pain under the left rib was due to the fact that that is where your stomach is located. Obviously the problem is more in the bowels, but I'm sure it can't be too great for the stomach when a flare up is taking place. My doctor said that the dizziness may be due to the pain experienced just before an episode. I get dizzy and to the point that I pass out if I don't sit down right away. Luckily, I am able to listen to my body well enough to sit down when I know it is coming, at least until I can get to the bathroom. Before we knew what was going on (when I was in elementary school) I would just pass out in the middle of class. My doctor said that sometimes when people are in pain they just hyperventilate without realizing it and the lack of oxygen causes the dizziness. He also said mine was probably due to low blood pressure since I already have pretty low BP to begin with.
