Headaches can be complicated. Different kinds can have their own set of symptoms, causes, and need different treatments.

Not all headaches are the same. Many headaches also cause other unwanted symptoms, including nausea and vomiting.

For secondary headaches, another disease or condition is the cause. The headache is a symptom.

Where your head hurts isn't a foolproof way to diagnose, but the location of your headache can be a starting point.

Migraine is a neurologic disorder that often causes a strong headache. In many people, it happens in stages.

There are key features that make migraine distinct from tension headaches and cluster headaches, which are rare.

if you have the condition known as chronic migraine, you get headaches 15 or more days a month for at least 3 months.

These headaches happen more than 15 days each month for at least 3 months. They can be migraine or tension headaches.

Cluster headaches are a series of relatively short but very painful headaches every day for weeks or months at a time.

It’s possible to have both migraine and cluster headaches, but your treatment depends on which one is causing your pain.

Tension headaches are also called stress headaches, and they’re the most common type for adults.

The symptoms you get, how long they last, and how intense they are can be different for migraines and tension headaches.

This rare type of continuous headache doesn't stop. It causes pain on one side of your face or head. 

Hypnic headache syndrome is a disorder that happens only while you’re asleep and mostly affects women over 50. 

Ice pick headaches feel like someone’s stabbing your face with an ice pick. They're also called stabbing headaches.

New daily persistent headaches (NDPH) begin without warning and go on for 3 months or longer.
