The study was conducted to see the relationship of headache with sinusitis. Sinus headaches are a very common complaint that are encountered by ENT surgeons. A structured questionnaire consisting of 16 questions which evaluates the type and severity of headaches and associated factors in people with sinusitis was used in the study. Sinus headache is not included in any classification of headache as an independent entity. Most people tend to self-diagnose wrongly. Therefore, unless there is any evidence or diagnosis of rhinosinusitis sinus headaches are mostly misinterpreted for migraine headaches
