There are three main types of headaches: primary headaches which include tension, migraine, and cluster headaches with the latter affecting more men in their late 20s; secondary headaches which are due to underlying structural issues in the head or neck; and cranial neuralgias, facial pain and other headaches, with neuralgias involving sudden nerve pain and facial neuralgias being unilateral pains limited to the affected cranial nerve's distribution.
