Most headaches are tension-type headaches or migraines; a small number signal a more serious problem. This article is general information, not medical advice.
1. Key points
Tension headaches often feel like a band of pressure.
Migraines can cause throbbing pain, nausea and light sensitivity.
Triggers can include stress, poor sleep, skipped meals and dehydration.
Get emergency care for a sudden, severe 'worst ever' headache or one with weakness, confusion, fever or stiff neck.
2. Tracking
A headache diary (time, food, sleep, stress) can reveal patterns.
