I never had any stomach pain that wasn't my normal Crohn's pain. But, I have experienced some dizziness for a week or so after one of my infusions. It's sort of a heavy-headed, loppy feeling, not dizzy like falling down with no balance. I say my head feels wobbly. I take Allegra before I go in (precaution, don't know if it matters) and now the wobbly feeling only lasts a day and is very minimal -- more like I have a head stuffed with cotton balls.
