Nasal mucosal headache presenting as orofacial pain: a review of the literature and a case report.

Headaches are a significant component of many facial pain syndromes. These facial pain/headache syndromes often have various etiologies, including neurologic, vascular, musculoskeletal, or combinations of vascular/musculoskeletal origins. Referred rhinologic headache, however, can be overlooked as a cause of facial pain in the dental literature. We report a case of nasal mucosal headache that presented as facial pain and include a review of the literature.
