Tension Headache & Chronic Daily Headache"Tension-type" headaches, or tension headaches, are the most common type of headache. About 30% to 80% of adults occasionally experience this kind of headache. Tension headaches are more common among women than men. These headaches are sometimes called stress headaches, muscle contraction headaches, daily headaches, or chronic non-progressive headaches. Tension headaches usually begin gradually and often occur in the middle of the day. A tension headache may occur on an episodic basis (less than 15 days per month) or on a chronic basis (daily or more than 15 days per month). Most people with episodic tension headaches have them no more than once or twice a month, but the headaches can occur more frequently. What Causes Tension Headaches?There is no single cause for tension headaches. This type of headache is not an inherited trait that runs in families. In some people, tension headaches are caused by tightened muscles in the back of the neck and scalp. In others, tightened muscles are not part of tension headaches, and the cause is unknown. Tension headaches are usually triggered by some type of environmental or internal stress. The most common sources of stress include family, social relationships, friends, work and school. Episodic tension headaches are usually triggered by an isolated stressful situation or a build-up of stress. Daily stress can lead to chronic tension headaches. What Are the Symptoms?In mild to moderate tension headaches, there is a constant, band-like pain or pressure that lasts from 30 minutes to all day. Tension headaches tend to be moderate or mild and are rarely severe. Unlike migraines they are not usually unilateral, throbbing or associated with light and sound sensitivity or nausea and vomiting. Other features of tension headaches may include:
