Overview
Tension headache involves intermittent episodes of head discomfort that are mild to moderate in intensity, include non-throbbing "tightness" or "pressure," generally on both sides of the head, and are not aggravated by routine physical activity. Nausea, vomiting, and light/sound sensitivity are rarely present.
Tension headache may last from 30 minutes to 7 days, occurring on more than 1 but fewer than 15 days a month. If headaches are present 15 or more days in a month, the tension headache is considered chronic tension headache (see Chronic Tension Headache topic). People who use pain medications for tension headaches, especially if used regularly, are more prone to developing chronic tension headache. In some cases, not treating the tension headache at all, called undertreatment, can also cause the headache to become chronic tension headache.
Immediately seek medical attention if you or someone you are caring for experiences any of the following:
- Stiff neck and a high fever associated with headache
- Sudden onset of a severe headache
- Loss of motor function, the ability to think clearly, or convulsions associated with headache
- Head injury
- Increased intensity and/or frequency of headaches
