Headache caused or made worse by activity

A headache that is caused by or made worse with activity can be alarming, especially if the headache is caused by sexual activity. The headache pain is usually sudden and pulsating. Most of these headaches are not serious, and go away by themselves. They often are caused by changes in blood flow to the head (vasodilation). Symptoms are usually relieved by lying down.

While headaches that are caused or made worse by activity are usually not serious, they may indicate a more serious problem, such as a subarachnoid hemorrhage.

If you have persistent headaches with any form of activity, an evaluation by your health professional is needed. A sudden, severe headache that is brought on by activity requires immediate medical attention.
