Abstract
Nummular headache is characterized by head pain exclusively felt in a sharply contoured, rounded, or elliptical area of the scalp, fixed in size and shape, and typically 1–6 cm in diameter. The affected area may show variable combinations of hypoaesthesia, dysaesthesia, paraesthesia, allodynia, and/ or tenderness. The symptomatic area may be localized in any part of the head but mostly in the parietal region. Rarely, the disorder may be multifocal, with each symptomatic area retaining all the characteristics of nummular headache. The pain is continuous or intermittent, and generally chronic. Nummular headache is a primary condition.
