Thunderclap headaches are dramatic. Symptoms include pain that:

  • Strikes suddenly and severely — sometimes described as the worst headache ever experienced
  • Peaks within 60 seconds
  • Lasts anywhere between an hour and 10 days
  • Can occur anywhere in the head, and may involve the neck or lower back
  • Can be accompanied by nausea, vomiting or loss of consciousness

When to see a doctor

Seek immediate medical attention for any headache that comes on suddenly and severely.
