Primary headaches account for up to 90 percent of all headaches. Common types include:
- Tension headaches: Tension headaches feel like a band of pressure or dull pain around your head. The discomfort may spread into your neck and shoulders. Related factors often include stress, depression, anxiety and poor sleep. Tension headaches that occur more than 15 days per month are considered chronic.
- Migraine headaches: Migraine headaches cause moderate to severe throbbing pain, often on one side of your head. You may also have other symptoms, such as light and sound sensitivity, nausea, vomiting and vision disturbances. Some people have specific factors that trigger their migraines. Common triggers include hormonal changes, stress, poor sleep, skipping meals and weather changes.
- Cluster headaches: Cluster headaches are rare but cause excruciating pain around one eye. They usually strike quickly, last less than four hours and occur at the same time each day. Chronic cluster headaches happen daily for long periods of time.
