If you get headaches regularly, knowing which type you have makes a real difference, because the triggers, treatments, and prevention strategies differ. The three most common primary headaches, migraine, tension-type, and cluster, each have a recognizable signature. This guide compares them so you can describe your symptoms more precisely and get more useful help.
Tension-type headache
This is the most common headache. The pain is usually a dull, steady pressure or tightness on both sides of the head, often described as a band squeezing the skull. It tends to be mild to moderate, does not usually worsen with activity, and is not typically accompanied by nausea. Stress, poor posture, screen time, jaw clenching, and lack of sleep are common triggers.
Migraine
- Pain is often one-sided, throbbing, and moderate to severe.
- Frequently comes with nausea and sensitivity to light, sound, or smell.
- Movement tends to make it worse, so people seek a dark, quiet room.
- Some people get an "aura" first, such as flashing lights or zigzag lines.
- Attacks can last from hours to a few days, and common triggers include hormonal changes, certain foods, missed meals, dehydration, and stress.
Cluster headache
Cluster headaches are less common but extremely intense. The pain is sharp and centered around or behind one eye, often striking at the same time each day in bouts ("clusters") that last weeks before easing. On the affected side, the eye may water and redden, the eyelid may droop, and the nostril may run or block. Unlike migraine sufferers, people with cluster headaches often feel restless and pace during an attack.
A quick comparison
- Location: tension is both sides; migraine is often one side; cluster is one eye.
- Quality: tension is pressing; migraine is throbbing; cluster is sharp and piercing.
- Severity: tension is mild to moderate; migraine is moderate to severe; cluster is very severe.
- Extras: tension has few; migraine adds nausea and light or sound sensitivity; cluster adds a watering or red eye and runny nostril on one side.
Don't assume a headache is just a usual type if it's different
Call 911 (US/Canada), 999 (UK), or 112 (EU) for a sudden "worst headache of your life," or a headache with confusion, weakness or numbness on one side, slurred speech, a stiff neck with fever, vision loss, or after a head injury. A new, unusual headache deserves urgent attention even if you usually get headaches.
When to see a doctor
Book a non-urgent visit if your headaches are becoming more frequent or severe, are not controlled by usual measures, or are interfering with work and life. Cluster headaches in particular benefit from specialist assessment, and frequent migraines may be eligible for preventive approaches a doctor can tailor to you. Avoid relying on daily over-the-counter painkillers, which can cause a separate medication-overuse headache; a pharmacist or doctor can guide safe use.
Keeping a headache diary, noting timing, triggers, symptoms, and what helps, gives a clinician the detail they need.
