With my son, gluten intolerance expressed with vit B6 deficiency, bloody diarrhea and a migraine that didn't let up for years. As a matter of fact, that was how we discovered it. Just by luck we were referred to a neurologist for the headaches and he figured it out. "First we look at the blood, *then* we look at the brain!"

That's a pretty severe consequence. I hope the diagnosis and corrective action solved his problem.
