* [[cluster headache]]s: short episodes (15–180 minutes) of severe pain, usually around one eye, with autonomic symptoms (tearing, red eye, nasal congestion) which occur at the same time every day. Cluster headaches can be treated with triptans and prevented with prednisone, ergotamine or lithium.
* [[trigeminal neuralgia]] or [[occipital neuralgia]]: shooting face pain
* [[hemicrania continua]]: continuous unilateral pain with episodes of severe pain. Hemicrania continua can be relieved by the medication [[Indometacin|indomethacin]].
* [[Ophthalmodynia periodica|primary stabbing headache]]: recurrent episodes of stabbing "ice pick pain" or "jabs and jolts" for 1 second to several minutes without autonomic symptoms (tearing, red eye, nasal congestion). These headaches can be treated with indomethacin.
* primary cough headache: starts suddenly and lasts for several minutes after coughing, sneezing or straining (anything that may increase pressure in the head). Serious causes (see secondary headaches red flag section) must be ruled out before a diagnosis of "benign" primary cough headache can be made.
* primary exertional headache: throbbing, pulsatile pain which starts during or after exercising, lasting for 5 minutes to 24 hours. The mechanism behind these headaches is unclear, possibly due to straining causing veins in the head to dilate, causing pain. These headaches can be prevented by not exercising too strenuously and can be treated with medications such as indomethacin.
* [[Sexual headache|primary sex headache]]: dull, bilateral headache that starts during sexual activity and becomes much worse during orgasm. These headaches are thought to be due to lower pressure in the head during sex. It is important to realize that headaches that begin during orgasm may be due to a subarachnoid hemorrhage, so serious causes must be ruled out first. These headaches are treated by advising the person to stop sex if they develop a headache. Medications such as [[propranolol]] and [[diltiazem]] can also be helpful.
* [[hypnic headache]]: a moderate-severe headache that starts a few hours after falling asleep and lasts 15–30 minutes. The headache may recur several times during the night. Hypnic headaches are usually in older women. They may be treated with [[lithium (medication)|lithium]].
