Migraine.

I am saved by painkillers. Although I know I need to see a doctor.

A migraine can cause severe throbbing pain or a pulsing sensation, usually on one side of the head. Migraine attacks can last for hours to days, and the pain can be so severe that it interferes with your daily activities. Medications can help prevent some migraines and make them less painful. The right medicines, combined with self-help remedies and lifestyle changes, might help. In fact, you can't tolerate a headache, because it can lead to a stroke.
