Red Flags & When to Go In Person for Cluster Headache - Triage

Audience: adult

Cluster headaches are severe headaches that often cause intense pain around one eye or one side of the head. They usually happen in groups or "clusters" over weeks or months. While cluster headaches are very painful, they are not life-threatening. However, some symptoms may signal a more serious problem that needs urgent medical care. This guide helps you understand when to seek in-person care and what signs to watch for. Telemedicine can support managing cluster headaches by reviewing symptoms and advising on treatments, but it cannot replace emergency care or detailed physical exams. If you experience sudden changes in your headache pattern, new neurological symptoms, or other warning signs, it's important to get prompt in-person evaluation. Knowing these red flags can help you stay safe while managing your headaches.
