Prevalence of Migraine in Patients With a History of Self-reported or Physician-Diagnosed "Sinus" Headache

In this study, 88% of patients with a history of "sinus" headache were determined to have migraine-type headache. In patients with recurrent headaches without fever or purulent discharge, the presence of sinus-area symptoms may be part of the migraine process. Migraine should be included in the differential diagnosis of these patients.
