Possible causes of sharp head pains are migraines or tension, cluster and sinus headaches. Some causes of headaches include unexplained nerve activity, colds, infections or fevers, according to WebMD.

Tension headaches are the most common type of headache. Also referred to as chronic or daily headaches, the muscle contractions that occur cause mild-to-moderate pain that comes and goes over a prolonged time frame, explains WebMD. The specific causes of migraines are unknown, as of 2015. One theory suggests that they are the result of abnormal brain activity that changes the blood vessels in the brain. Pain from migraines ranges from moderate to severe, and they may last up to three days.

Additional symptoms of a migraine include sensitivity to smells, light and sound, nausea, loss of appetite, and stomach pain, according to WebMD. Children experiencing a migraine usually appear pale and dizzy and complain of an upset stomach or blurred vision.

Cluster headaches are the least common but most severe variety. Many people who experience cluster headaches feel such intense pain that they can't sit still and pace around during an episode, notes WebMD. The pain associated with cluster headaches is located in the area of one eye and does not change sides. Episodes may happen two or three times a day within a period which lasts two weeks to three months.
