Abstract
Headache and facial pain disorders are prevalent, disabling, and largely treatable, but are under-recognized, underdiagnosed, and undertreated, and a burden, both to the individual and to the society. Headache and facial pain cuts across a diverse group of physicians, including neurologists, neurosurgeons, headache specialists, otolaryngologists, dental specialists, anesthesiologists, and pain specialists. This review discusses the relevant neuroanatomy, the updates in pathophysiology, and classification of headache and facial pain disorders. We will also introduce the art of history-taking in headache patients, as well as physical examination, investigation, and treatment of the most common disorders.
