Patients with a history of "sinus" headache, no previous
diagnosis of migraine, and no evidence of infection were assigned a
headache diagnosis on the basis of headache histories and reported symptoms.
A total of 2991 patients were screened. In this study, 88% of patients
with a history of "sinus" headache were determined to have
migraine-type headache. The most common symptoms relative to the sinus
area were sinus pressure (84%), sinus pain (82%), and nasal congestion
(63%). In patients with recurrent headaches without fever or discharge,
the presence of sinus-area symptoms may be part of the migraine process.
The possibility of migraine should be included in making a diagnosis
in these patients. Schreiber CP, et al. l. “Prevalence of migraine
in patients with a history of self-reported or physician-diagnosed "sinus"
headache.” Archives of Internal Medicine. 164(16):1769-72, 2004
