Why do so many Why do so many Americans think they Americans think they have have Sinus Sinus Headache? Headache? In his 1988 review, “Sinus Headache: A Neurologist’s Viewpoint,” Couch writes:
In my experience and in that of others, “sinus headache,” as reported by patients, is a popular conception that is often erroneous. Patients reason that, since the sinuses are close to the eyes (as depicted in advertisements in popular magazines), headaches located in the frontal, supraorbital, or infraorbital region are sinus headaches… [These] headaches frequently are associated with some gastrointestinal symptomatology, photophobia, and phonophobia, and may have some visual or neurologic symptoms. In short, these “sinus headaches” are usually migraine headaches, most often of the common migraine type.
