Q Why does a cluster headache cause such excruciating pain?
A Because a rhythm-regulation error in the hypothalamus makes the trigeminal and autonomic nerves fire explosively all at once.
Detailed Answer
Simultaneous Surge of the Trigeminal and Autonomic Nerves
A cluster headache is triggered by a malfunction of the hypothalamic biological clock. When the hypothalamus over-activates the trigeminal nerve, severe one-sided pain lasting 15 to 180 minutes develops around the eye socket and temple. At the same time, the autonomic nerves become excited, producing conjunctival redness, tearing, runny nose, and an ipsilateral Horner's syndrome (drooping eyelid and constricted pupil).
Korean Medicine Clinic Perspective — Liver-Fire Flaring Upward
At Dongjedang, we view the core pathology of cluster headache as Liver-Fire flaring upward (ganhwa-sangyeom) and qi stagnation with blood stasis (giche-hyeoeo). When excessive stress, alcohol, or irregular sleep blocks the liver's function of free coursing (soseol), heat surges upward and intensely irritates the blood vessels of the eye and temple. This is not a simple headache but a signal that the body's heat-circulation system has broken down.
