Tension headaches are the most common kind of headaches. They cause aching, tightness, pressure, and pain around the forehead, temples, or back of the head and neck. They tend to happen again and again, especially if you are under stress. They aren't usually a sign of anything serious.

Some people have chronic tension headaches, which means they have a headache on 15 or more days a month. This type of headache can lead to stress and depression, which in turn can lead to more headaches.
