Migraine and Headache Terms of the Day - Allergen and Antigen

Teri Robert @trobert Health Guide
  • Do you know what the terms "allergen" and "antigen" mean when discussing Migraines and headaches? When we're looking at Migraine and headache information, whether it's from our doctor, a book, or an online article, we sometimes come across medical terms that can be confusing.


    Sometimes, it's easy enough to substitute another word or a short phrase for the medical term. At other times, substituting just doesn't convey quite the same meaning or takes more than a few words.


    Some of you have expressed an interest in learning more of the medical terminology that comes up when discussing Migraine disease and other headache disorders. So, Ellen and I will continue with these posts to help us all be better prepared to manage our health and work with our doctors as treatment partners.
