Cefaly is a newly-FDA-approved device that prevents migraines. Users wear the plastic headband across forehead, over ears, with electrode stuck to mid-forehead for 20 minutes daily. It stimulates trigeminal nerve to prevent migraines.
It is the first TENS unit approved for use prior to pain onset. Studies indicate that it does not completely prevent migraine attacks, but those who used it had fewer headaches per month and used fewer migraine medications per month.
