Cluster headaches are distinct from migraines. They are strictly one-sided, centered around the eye, and incredibly intense — often rated as the most painful condition known to humans.
Unlike migraines, clusters always involve autonomic symptoms: a drooping eyelid (ptosis), a red eye, or a stuffed nostril on the pain side. They occur in "clusters" of weeks or months, followed by periods of remission.
Standard migraine pills are often too slow. Cluster attacks require high-flow oxygen or specific injectable medications. If you experience strictly one-sided attacks with eye involvement, track the pattern — this is the fastest way to secure the correct diagnosis.
The Relief app correlates your attacks with weather, sleep, food, and more — automatically.
