Paroxysmal Hemicrania
A primary headache disorder that is similar to the CLUSTER HEADACHE with unilateral head pain, but differs by its multiple short severe attacks. It is usually seen in females, and may be responsive to non-steroidal-anti-inflammatory drugs (NSAIDS).
Trigeminal Autonomic Cephalalgias
Primary headache disorders that show symptoms caused by the activation of the AUTONOMIC NERVOUS SYSTEM of the TRIGEMINAL NERVE. These autonomic features include redness and tearing of the EYE, nasal congestion or discharge, facial SWEATING and other symptoms. Most subgroups show unilateral cranial PAIN.
Cluster Headache

The attacks are associated with one or more of the following, all of which are ipsilateral: conjunctival injection, lacrimation, nasal congestion, rhinorrhea, facial SWEATING, eyelid EDEMA, and miosis.
