What is a characteristic feature of a tension-type headache?

A characteristic feature of a tension-type headache is its moderate intensity. Unlike migraine headaches, which can often present with severe throbbing or pulsating pain, tension-type headaches typically involve a more constant, pressing quality of mild to moderate intensity. These headaches often feel like a tight band or pressure around the head rather than a sharp or pulsating sensation.

Tension-type headaches are also generally bilateral in location, meaning they are felt on both sides of the head, which associated with feeling of tightness rather than a painful pulsating nature. The duration of tension-type headaches can vary, but they often last anywhere from 30 minutes to several days, which makes a duration of less than 4 hours not a distinguishing feature of this headache type.

Thus, the hallmark of tension-type headaches lies in their moderate intensity, making this characteristic notable in differentiating them from other headache disorders.
