Clinical Trial: Prevalence of Phonophobia and Cutaneous Allodynia in Episodic Migraineurs

Official Title: Prevalence of Phonophobia and Cutaneous Allodynia in Episodic Migraineurs

Brief Summary: Cutaneous allodynia is an increased skin sensitivity experienced during a headache. It has been noted in several studies that in patients with migraine, seventy nine percent of the patients experienced allodynia on the facial skin on the same side as the headache. Understanding more about the occurrence of phonophobia (increased sensitivity to sound) and allodynia may help us understand how the pain system works in migraine. It is hoped that the knowledge gained from this trial may enable us to more effectively treat patients with migraine headache.

Current Primary Outcome: Correlation Between Phonophobia (Sound Sensitivity) and Allodynia (Skin Sensitivity) in Subjects With Episodic Migraine [ Time Frame: Subjects with or without allodynia return during a migraine attack and are tested for Phonophobia. ]

Measurement of phonophobia: determine sound aversion threshold (SAT), measured in dB during a migraine attack in subjects with and in subjects without allodynia.
