Signs of tension headaches
When someone complains of a headache, they’re likely suffering from a tension-type headache — your common, “everyday” headaches that produce a dull, squeezing pain often described as a band around the head.1,2
Tension-type headaches may last anywhere from 30 minutes to several days.1 Tension headaches may be episodic or chronic. Episodic tension headaches occur on fewer than 15 days a month. If they’re happening more frequently than 15 days per month, for at least three months, they’re classified as chronic tension headaches.2
Tension headaches often come on gradually, and typically occur in the middle of the day.3 It’s estimated that 30 to 80 percent of adults in the United States experience episodic tension headaches, while three percent experience chronic ones. Women are twice as likely to experience tension headaches as men.3
