Rhinogenic contact point headache - Frequently missed clinical entity

Headache is a common clinical entity and is nearly universal in the course of everyone's life. Pressure of two opposing mucosa in the nasal cavity without evidence of inflammation can be a cause of headache or facial pain. Minor intranasal anatomical variation leading to mucosal contact point may be an etiological factor for causing headache and often misdiagnosed and forgotten by clinician during evaluation of headache patients and sometimes considered as headache of unknown etiology.
