The pain is severe in patients with CPH, and attacks are associated with autonomic features, such as the following:

  • Lacrimation - 62%

  • Conjunctival injection - 36%

  • Ipsilateral nasal congestion - 42%

  • Rhinorrhea - 36%

  • Eyelid edema - 33%

Lacrimation may occur bilaterally but is always more marked on the symptomatic side. Occasionally, mild ipsilateral miosis may be observed during attacks.
