There are many types of headaches. These vary in their causes, how they feel, how severe they are, how long they last and how they respond to different treatments.

Type of headache	Description
Tension headache	This is the most common type of headache. It usually begins with shoulder or neck tension and may feel like a tight band around your head, a dull ache on both sides of your head, or a heavy weight on top of your head. Tension headache can last for a few hours to days and they tend to develop later in the day. They are usually brought on by lifestyle issues such as working too much or not getting enough sleep, poor posture and emotional stress or anxiety. Read more about tension headache.
Migraine	In migraine the pain is usually one-sided, throbbing, quite intense and can make you feel weak and exhausted. They last from a few hours to days. Migraine most commonly brings other symptoms, such as nausea, vomiting and aversion to light and noise. Some people may have a migraine aura before the headache begins, which could be problems with your eyes such as seeing zig-zag lines, dizziness, or a pins-and-needles feeling. More women than men suffer from migraine, and it is common in children, teenagers and young adults but may begin at any age. Treatment of migraines includes lifestyle changes and using medications for relief or, in some cases, using preventive medicines to stop a migraine from happening. Read more about migraine.
Cluster headache	Cluster headaches often occur at night and usually cause sudden pain on one side of your head – often around your eye. They can happen several times a day for a period of time, then disappear for months or years. If you get cluster headaches, try to identify the triggers and avoid those things. If they become a problem, see your doctor.
Sinus headache	Sinus headache is described as pain around the eyes, forehead, cheeks or teeth which gets worse when leaning forward. It can be dull or severe. It is often associated with other symptoms of sinusitis such as a blocked or stuffy nose, feeling of pressure inside your head, mucus from your nose and a post-nasal drip. Read more about sinusitis.
Medication overuse headache	Medication overuse (or rebound) headache can happen from using too much pain relief medication to treat headaches. It may feel like a tension-type headache or migraine-like attack. Headaches often improve within 2 to 4 weeks of withdrawal of the overused medicine but can feel worse before improvement is seen. To avoid this, limit the use of pain relief medication – use them for the shortest possible time, only when you have pain. For example, paracetamol and NSAIDs should not be taken for headache on more than 15 days per month and triptans for migraine should not be used for more than 10 days per month.

What causes headaches?

The cause of headache will usually depend on the type of headache. There are many different causes of headaches including:

muscle tension
an infection elsewhere in your body
inflamed arteries (which cause migraine or cluster headaches)
the toxic effects of alcohol or other substances.

Headaches can be triggered by stress, tiredness, dehydration, hunger, certain foods, constipation, eyestrain, noise or bright light.

When should I see my doctor about headaches?

Usually, headaches go away given time, rest and/or treatment with a pain relief medication. You should see your doctor if:

your headaches remain frequent, persistent or worsen
you get no relief from simple pain relievers
you take simple pain relievers more than twice a week
you were headache-free but now get them
your headache is triggered by standing up, coughing, straining, physical exertion or sexual intercourse
you are over 50 and start to get regular headaches or there is face or jaw pain.

If a friend or family member has any of the urgent symptoms listed in the box at the top of this page, seek immediate medical help.

The treatment of your headache will depend on the cause and will vary depending on the specific type of headache. Here are a few general things you can do.

drink a large glass of water
take pain relief medication
- paracetamol, aspirin or ibuprofen are simple pain relievers (analgesics) that can ease occasional tension headaches

rest in a dark, quiet room
have someone give you a head, neck and shoulder massage
