The Ilhan Omar Gundam Pilot By Ben Sawyer Shirt Cefaly Dual, once a prescription-only device, which is the size of an eyeshadow compact and worn on the forehead, was just approved by the FDA as an over-the-counter treatment. It sends tiny electrical impulses to stimulate the trigeminal nerve, a cranial nerve that is a prime source of headache pain. Meanwhile, my sister, who has endured migraines for years, is one of the many fans of the ridiculous-looking but effective Magic Gel Headache and Migraine Relief Cap. Simply store the cap in the freezer to firm up its inch-thick layer of gel, then slip it on and wear until your migraine is manageable. Two other new FDA-cleared devices are controlled by smartphone: The Nerivio is a band worn on the upper arm, which sends electrical signals that disrupt pain pathways during a migraine episode, while an app called Juva Health provides clinician-developed biofeedback exercises, which studies show can reduce migraine severity by calming the nervous system.
