Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT), a rare disorder, resembles cluster headaches. It usually causes short but frequent bouts of pain around the eye on one side of the head.
(See also Overview of Headache.)
Because of their similarities, SUNCT and cluster headaches are often grouped together as trigeminal autonomic cephalgias. Trigeminal autonomic cephalgias also include chronic paroxysmal hemicrania, and hemicrania continua—all very rare disorders.
Usually, pain occurs around the eye on one side of the head. People may have up to 200 bouts of pain a day, and the pain may last from 5 seconds to over 4 minutes. The affected eye is red (called conjunctival injection) and frequently waters (tears).
Short-lasting unilateral neuralgiform headache with cranial autonomic symptoms (SUNA) is similar to SUNCT. It differs from SUNCT in that it involves conjunctival injection (blood shot eyes) or tearing, but not both. Other symptoms of SUNCT and SUNA are similar. Both are short-lasting unilateral neuralgiform headaches.
Doctors diagnose SUNCT based on symptoms. Magnetic resonance imaging (MRI) is done to rule out other causes.

Lidocaine
To prevent attacks, antiseizure medications or injection of certain medications
Lidocaine (an anesthetic) is given intravenously to relieve immediate pain.
To prevent attacks, doctors may give people antiseizure medications (such as lamotrigine, topiramate, or gabapentin) or inject agents to block or stimulate the nerve that supplies the affected eye (optic nerve).
