Cluster headaches
(Cilliary, neuralgia, Horton's syndrome, histamine cephalgia and
migrainous neuralgia)
Definition and Presentation
Pain occurring in one side of the
face in clusters from several days to weeks. It then abates to
recur after months or even years later. The pain is usually
localised around the eye in the temple behind the ear and in the
back of the jaw.

A number of drugs can be used. Gamma Knife surgery focused on
the trigeminal nerve root has been used in a few cases refractory
to drugs.
