Headache and rhinosinusitis are 2 of the most common conditions seen in clinical practice. In general, chronic and disabling headaches, especially if migraine features are present, are not due to sinus abnormalities. ⋯ Although most cases of sinusitis are fairly easy to diagnose, sphenoid sinusitis may be overlooked, and can present with progressive or thunderclap headache in adults. Contact-point headache should be considered in patients with focal headaches and a contact point on the lateral nasal wall.
