This headache has also been called “coin-shaped headache” because it occurs in a small circumscribed area of the scalp, similar to a coin shape. It can occur anywhere, but tends to occur most often in the sides of the head (parietal areas). It is usually a single spot, but can rarely be in multiple areas. It has a fixed shape and size, sharply-contoured, should be round or elliptical, and averages 1-6 cm in diameter. The pain can be continuous or intermittent lasting hours, days, minutes, or seconds, but most often is a continuous pain (chronic). It is usually mild or moderate pain, but can occasionally be more severe. The area of pain may also feel sore, sensitive, tingling, or seem to have less sensation.
