Migraine Term of the Day: Allodynia

Patient Expert

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, I'll be posting a "term of the day," probably a couple of times a week. If there are terms you'd like to have defined, please leave a comment to let me know what it is.

Today's term: Allodynia.

Allodynia a condition in which an ordinarily painless stimulus is experienced as being painful.

When discussing Migraine disease and other headache disorders, we generally see Allodynia listed as a possible of a Migraine attack. During a Migraine, we can experience cutaneous (of the skin)** allodynia**. You've probably heard people say that even their hair hurts during a Migraine. That's** allodynia**. It can hurt to touch your head, brush your hair... for some people, allodynia can affect the entire body for a time, making even clothes or bed linens against their skin uncomfortable.
