Symptoms - Migraine

Common symptoms of a migraine

The main symptom of a migraine is usually an intense headache on one side of the head.

The pain is usually a moderate or severe throbbing sensation that gets worse when you move. It can prevent you carrying out normal activities.

Sometimes, the pain can occur on both sides of your head. It may also affect your face or neck.

Additional symptoms

Other symptoms of a migraine include:

  • feeling sick
  • being sick
  • sweating
  • poor concentration
  • feeling very hot or very cold
  • tummy pain
  • diarrhoea
  • increased sensitivity to light and sound

Not everyone with a migraine experiences these other symptoms. Some people have them without having a headache.

The symptoms of a migraine usually last between 4 hours and 3 days. You may feel very tired for up to a week.

Symptoms of aura

About 1 in 3 people with migraines get warning symptoms before a migraine. This is called "aura".

These include:

  • visual problems – such as seeing flashing lights, zig-zag patterns or blind spots
  • numbness or a tingling sensation like pins and needles – starting in 1 hand and moving up your arm before affecting your face, lips and tongue
  • feeling dizzy or off balance
  • difficulty speaking
  • loss of consciousness – this is unusual

Aura symptoms can develop over about 5 minutes and last for up to an hour.

Some people may experience aura followed by only a mild headache or no headache at all.

When to contact your GP

You should contact your GP if you have frequent or severe migraine symptoms that you cannot manage with over-the-counter painkillers.

Try not to use the maximum dosage of painkillers often. This could make it harder to treat headaches over time.

You should contact your GP if you have frequent migraines even if you can manage them with medicine. Frequent migraines means a migraine on more than 5 days a month. Preventative treatment may help you.

Immediate action required: Call 999 or 112 for an ambulance immediately if you or someone you're with experiences:

  • paralysis or weakness in one or both arms or one side of the face
  • slurred or garbled speech
  • a sudden very painful headache resulting in a severe pain unlike anything experienced before
  • headache along with a high temperature (fever), stiff neck, mental confusion, seizures, double vision and a rash

These symptoms may be a sign of a more serious condition and should seen by a doctor as soon as possible.

Stages of a migraine

Migraines often develop in distinct stages. But not everyone goes through all of these.

Prodromal (pre-headache) stage

Changes in mood, energy levels, behaviour and appetite that can happen several hours or days before an attack.


Usually visual problems, such as flashes of light or blind spots. This stage can last for 5 minutes to an hour.

Headache stage

Usually a pulsating or throbbing pain on one side of the head. This stage is often accompanied by feeling sick, vomiting or extreme sensitivity to bright light and loud sounds. It can last for 4 to 72 hours.

Resolution stage

When the headache and other symptoms fade away, you may feel tired for a few days afterwards.
