  • Characterized by unilateral pain in the orbit, mouth, nose, and posterior mastoid process.
  • Also associated increased autonomic activity resulting in ipsilateral nasal drainage, eye irritation, and lacrimation
  • May be caused by irritation of the pterygopalatine ganglion, possibly secondary to infection
  • Typically female 2:1 male predominance
