Many people will, at some point, experience a headache (less than two percent of the population have never had one, claims the NHS). More than 10 million people in the UK get headaches regularly, which means they’re one of the most common problems to affect the nation’s health.

There are two main types of headache: primary headache, which is a headache that isn’t due to any underlying health problem; and secondary headache, which is a headache caused by a separate illness or injury.

Primary headaches are much more common than secondary headaches – more than 90 percent of visits to GPs for headaches are thought to be for the primary kind, with fewer than 10 percent of visits for secondary headaches.

Experts aren’t clear about what exactly causes primary headaches, though several things seems to trigger them, including stress, drinking too much alcohol, not drinking enough water (dehydration), not eating regularly and being tired after not getting a good night’s sleep.

Some other things that may trigger a headache include anger, poor posture, changes in the weather or stormy weather, bright lights, some smells (such as perfume, air fresheners and household cleaners) and even eating ice cream (ice cream headaches cause a sharp, stabbing pain in the forehead when you eat ice cream or ice lollies). Certain foods can also bring on a headache, though food triggers are normally associated with the type of headache known as a migraine (click here for more information on migraine).

 Meanwhile, causes of secondary headache include the following:

  • Head and/or neck trauma.

  • Cranial or cervical vascular disorders (including stroke).

  • Disorders of the neck, eyes or ears.

  • Sinusitis, colds and flu.

  • Temporomandibular disorders (problems that affect the muscles and joints between the lower jar and base of the skull).

  • Disorders of the teeth or jaws.

  • Carbon monoxide poisoning.

  • Drug withdrawal.

  • Underactive thyroid.

  • Sleep apnoea (which interrupts normal breathing during sleep).


Types of headache

As well as primary and secondary, there are different types of headache (migraine is classed as a primary headache – click here to read more about it):

  • Tension headache
    This is the everyday type of headache most people suffer from. The symptoms include a dull ache on both sides of the head, with a feeling of pressure around the head or behind the eyes. They can last anything from half an hour to several hours – although some tension headaches can last for days.

    According to the NHS, about half the adult population in the UK has tension headaches once or twice a month, with one in three people suffering from a tension headache up to 15 times a month (episodic tension headache). Two to three percent of adults also have tension headaches more than 15 times in a month (chronic tension headache).

    There are many causes, including stress, lack of sleep, skipping meals and not drinking enough (dehydration). Other triggers include bright sunlight, eye strain, loud noise, lack of exercise, poor posture and certain types of smells.

  • Cluster headache
    Cluster headaches can be incredibly painful, so it’s good to know they’re fairly rare. Around one in 1,000 people are thought to be affected, eight out of 10 of whom are men (mostly smokers). The symptoms typically include intense pain on one side of the head – usually around or behind one eye – that’s more severe than the pain of a tension headache or even a migraine.

    As with tension headache, a cluster headache can be episodic or chronic (episodic cluster headache is when you have a pain-free period of a month or more between clusters, while chronic cluster headache sufferers have pain-free periods of less than a month).

    It’s generally thought that cluster headache is linked to a part of the brain called the hypothalamus. Experts have studied what happens in the brain during an attack, and some believe the hypothalamus releases chemicals called neurotransmitters. These may cause pain by stimulating nerve cells in the brain. Another theory is that cluster headache may also be caused by the widening of blood vessels in the brain, which causes pain by adding pressure to tissues in the brain.

    Unfortunately, most cluster headaches don’t have any triggers, though some people who have them find things like alcohol, strong smells and being too hot can bring on an attack.

  • Hormone headache
    According to the NHS, many women – at least five million each month – have headaches that are linked to their menstrual cycle (experts believe they’re caused by changes in hormone levels). Other triggers for hormone headaches include taking the combined contraceptive pill, pregnancy and menopause. Hormone headaches are also often referred to as menstrual migraines.

  • Medication and painkiller headache
    Some headaches can be a side effect of taking certain medications, or can be caused by taking too many painkillers (or, rather, taking painkillers too often). The latter is often called medication-overuse headache or rebound headache, and experts believe around one in 50 people suffer from them, with women five times more likely to be affected than men.

    If you use painkillers such as paracetamol or ibuprofen on 15 or more days each month for more than three months, or prescription painkillers that contain opioids or other ingredients called triptans for 10 days a month, you may be diagnosed with medication-overuse headaches.

    Symptoms include having a chronic or continuous headache, a headache that may be worse during the mornings or a headache that gets worse when you’re active or exercising.

    If you’re suffering from medication-overuse headaches, you must see your GP for advice on stopping taking painkillers (depending on the type of painkiller, you may have to stop immediately or gradually).
     

Meanwhile there are several other types of primary headache, including exertional headache (which is triggered by exercise), cough headache (brought on by coughing or straining), sexual headache (caused by sexual activity) and hypnic headache (a dull headache that can wake you up and lasts at least 15 minutes after waking).


Pain relief for headaches

Most tension headaches can be treated with simple pain relief medicines that you can buy over the counter (for cluster or hormone headache treatments, see your GP). But which one should you choose?

  • Paracetamol
    Paracetamol is thought to act on the production of prostaglandins, substances produced by the body in response to injury that sensitise nerve endings involved in the process of inflammation.

    It’s available in tablets, including effervescent/dissolvable tablets, or as a liquid. Dissolvable paracetamol may treat symptoms more effectively as the active ingredient is absorbed by the body faster compared with a tablet.

    Combination remedies are also available for more persistent or severe headaches that contain both paracetamol and an opioid painkiller called codeine.

    Paracetamol on its own is suitable for adults, children over the age of two months and pregnant women.

  • Ibuprofen
    Ibuprofen is an anti-inflammatory painkiller that works by blocking a chemical called COX, an enzyme that helps your body produce prostaglandins. It may be a good option for headache sufferers who find paracetamol isn’t effective. However, it isn’t recommended for long-term use, as it can cause stomach-related side effects.

    It’s available in tablets, caplets and capsules and is suitable for adults and children over the age of three months (older people should use ibuprofen with care).

  • Aspirin
    Because aspirin can cause side effects in the stomach, it isn’t usually recommended for headaches. Aspirin is also found in pain relief medicines combined with other ingredients such as caffeine or paracetamol.

    Do not give aspirin to children under the age of 16. It’s also not suitable for pregnant women or people who have asthma.


When is a headache serious?

While the vast majority of headaches aren't serious, a very small number may indicate an underlying health problem. These serious headaches are more common in older people, and can appear very quickly and become worse over time. Here are some of the main examples:?Meningitis

A severe headache can be a symptom of meningitis, which causes an infection and inflammation of the tissues around the brain. Other symptoms include a high temperature, vomiting, muscle and joint aches and pains, sensitivity to bright lights and a stiff neck. More than 2,000 people are thought to be affected by bacterial meningitis every year in the UK, but figures for viral meningitis are not available, since the symptoms are often similar to those of flu.

  • Haemorrhage
    A sudden severe headache may also be a symptom of a subarachnoid haemorrhage, which is typically caused by an aneurysm. Thankfully, subarachnoid haemorrhages are very rare and are thought to affect just six to 12 people in every 100,000 each year. Other symptoms may include vomiting and seizures.

  • Temporal arteritis
    Usually confined to people over the age of 50, temporal arteritis causes a frontal headache (behind the forehead) and is caused by inflammation in the arteries behind the eye and in the temples. People who are affected may also feel generally unwell and experience pain in their jaw muscles while chewing. If left untreated, temporal arteritis can lead to loss of vision in one or both eyes.

  • Tumour
    Many people who have persistent, severe headaches fear the cause may be a brain tumour, but in reality this is very rare (both benign and malignant primary brain tumours are found in just 12 out of every 100,000 people a year). But if it is a tumour, you may also feel sick, and if you cough, sneeze or bend over, your headache may feel worse.

Thankfully most serious headaches aren’t at all common, but if any of the following applies to you, see your GP as soon as possible:

  • Your headache comes on suddenly and severely (especially if you've recently suffered a knock to the head).

  • Your headache is accompanied by a fever, convulsions, feelings of drowsiness or confusion, blurred vision or vomiting.

  • There's a dramatic change in your normal headache pattern

 

Natural headache relief

Nutritional or herbal supplements and natural treatments that may help to alleviate headaches include the following:


Vitamin B complex

If you tend to get headaches when you’re under too much stress, you may find that vitamin B complex – a supplement that contains a combination of B vitamins – helps. That’s because certain B vitamins are thought to help the body to cope better with the negative effects of stress. There is some evidence to support this: for example, a study found that taking a B complex supplement for 90 days may lead to a significant reduction in the experience of stress at work (i).


Sticks and strips

Designed to be applied directly to the forehead, these sticks and strips contain an ingredient called levomenthol (a type of peppermint). It’s thought that they may block pain signals caused by tension headaches and relax the muscles in the head.

Meanwhile natural treatments that may be worth trying for tension headaches include acupuncture, chiropractic, hypnosis, osteopathy and relaxation therapies.

Other things you can do to help relieve a headache include the following:

  • Lie down in a dark, quiet room and try to relax your back, neck and shoulders.

  • Try deep breathing – inhale and exhale to a slow count of five until you feel yourself relaxing.

  • Drink a glass of water (a headache can be a sign that you’re becoming mildly dehydrated).

  • Place a hot water bottle or ice pack at the back of your neck if your headache is accompanied by muscle tension.

  • Try acupressure – find the spots just below the base of the back of the skull in the hollows on both sides of the neck, about three inches apart (in acupressure these spots are called GB20). Press and massage both spots with your thumbs, fingers or knuckles while breathing slowly and deeply for up to three minutes.
