It is unknown what exactly causes a migraine but it is thought that they are the result of abnormal brain activity, which temporarily affects chemicals, nerve signals and blood vessels within the brain.
Exactly what sets off a migraine is different for everybody, but some migraine triggers include changes in hormones, some foods, emotional triggers such as stress, anxiety and shock, tiredness, dehydration, loud noises and bright lights.
A migraine usually feels very debilitating, with a throbbing or pulsing pain, which usually affects one side of the head.
Before a migraine starts, you may experience warning signs, or a migraine aura as it is known.
An aura may include flashes of light, blind spots or tingling on one side of the face or in your arms or legs.
As well as this, you might find it difficult to speak.
When an aura affects your vision, this is known as an ocular migraine or retinal migraine.
An aura can be a bit frightening if you have not experienced this before. But in most cases, they do not cause you any harm and they do not last for long.
You can also experience a migraine aura without headache, which is also known as a silent migraine.
This means that you may have specific migraine warning signs such as flashing lights but you do not go on to develop a headache.
During your migraine, you may find that lying in a darkened room, away from light and sound helps.
You may find that if you go to sleep, you will wake up feeling improved. Eating something can also help, especially if you have been sick or feel sick.
