Device, System and Method for Reducing Headache Pain

Abstract

A device for stimulating at least one cranial nerve and/or spinal nerve is described. The device includes a vibratory motor, and an earpiece, wherein the earpiece is molded substantially to fit within the external ear canal and contacting the concha of a subject's ear. A method of reducing migraine headache and trigeminal neuropathy pain is also described. The method includes positioning a vibratory earpiece within an ear of a subject, applying vibrational energy to at least a portion of the skin of at least one of the auditory canal, auricle and concha of the ear, thereby stimulating at least one sensory fiber of at least one of cranial nerve 5, cranial nerve 7, cranial nerve 9, cranial nerve 10, spinal nerve C2, and spinal nerve C3. A method to normalize breathing, normalize blood pressure, induce sleep, increase salivation, and improve vertigo, nausea, and visual dysfunction accompanying migraine is also described.
