Migraine is a complex disease with myriad possible symptoms, including allodynia. Some of these symptoms can be frightening; at the least, they're frustrating.
Simply put, allodynia is a condition in which an ordinarily painless stimulus is experienced as being painful. This condition can be a symptom of migraine, occurring during a migraine attack, or even between attacks.
We can experience cutaneous (of the skin) allodynia. Some examples of allodynia:
- It can hurt to even touch your head.
- It can hurt to brush or wash your hair.
- The face often becomes very sensitive to touch.
- For some people, allodynia can affect the entire body for a time, making even clothes or bed linens against their skin uncomfortable.
Researchers aren't sure of the mechanism yet, but allodynia has been shown to be associated with a higher prevalence of depression in migraine patients.
