Wow, that sounds aweful. I could be wrong, but as someone with food allergies myself (and it took me years to figure out which foods), my first thought is that your body doesn't like something that you've eaten. Have you noticed that any foods in particular trigger an episode? This forum post here: http://www.celiac.com/gluten-free/to...n-sensitivity/ , this person found out that it was misdiagnosed celiac or gluten sensitivity. I hope you feel better soon!
