A migraine is a severe, recurring headache often accompanied by nausea, vomiting, and sensitivity to light and sound. It's a neurological disorder caused by a combination of genetic and environmental factors that triggers changes in the brain stem and interactions between the trigeminal nerve and brain chemical imbalances. Migraines can be debilitating and impact one's quality of life. According to the American Migraine Foundation, nearly 1 in 4 U.S. households includes someone with migraine.
