In brief: Cluster headache
Cluster headache belongs to a group of idiopathic (unknown cause) headache entities known as the trigeminal autonomic cephalalgias, all of which involve one-sided, short-lived, severe headache attacks.
There are associated autonomic symptoms, such as ptosis (eyelid drooping), miosis (constricted pupils), lacrimation (tearing in the eyes), conjunctival injection, runny nose, and nasal congestion.
