What is a tension headache?
Most headaches are tension headaches. These headaches tend to happen again and again, especially if you are under stress. They are not usually a sign of something serious. But they can be very painful and hard to live with.

Tension headaches can last from 30 minutes to 7 days.

If you have a headache on 15 or more days each month over a 3-month period, you may have chronic tension headaches. This type of headache can lead to stress and depression, which in turn can lead to more headaches.

About 4 out of every 100 people in the United States get chronic tension headaches.  Symptoms can start in childhood, but they are more likely to occur during middle age.

Some people have both tension headaches and migraine headaches.

What causes tension headaches?
Doctors don’t know for sure what causes tension headaches. Experts once thought that tension or spasms in the muscles of the neck, face, and head played a role. Now they think that a change in brain chemicals also may be a cause.

Tension headaches are one of the most common types of headaches. They can be brought on-or triggered-by things such as stress, depression, hunger, and muscle strain. Tension headaches may come on suddenly or slowly.

What are the symptoms?
Symptoms of tension headaches include: A headache that is constant, not throbbing. You usually feel the pain or pressure on both sides of your head.  Pressure that makes you feel like your head is in a vise. Aching pain at your temples or the back of your head and neck.

This is different than migraine headaches, which usually cause throbbing pain and start on one side of your head.

Tension headaches tend to come back, especially when you are under stress.

Pain from a tension headache is usually not severe and does not get in the way of your work or social life. But for some people, the pain is very bad or lasts a long time.
