Migraine is a common yet debilitating condition which involves a moderate to severe headache, usually presenting as a throbbing pain on either side of the head, and is often accompanied by other symptoms such as nausea, vomiting and/or sensitivity to light or sound. Although migraines can present themselves at any age, they normally begin in young adulthood and are more prevalent in women. It is estimated that migraine affects 1 in 5 women compared with 1 in 15 men. The severity and frequency of migraines tend to improve with age, however this is not always the case for everyone. 

Symptoms of migraine attacks are personal to the individual, with sufferers experiencing different symptoms with varying degrees of impact on their day-to-day life. Migraine attacks can vary in frequency, from 1-2 a month to 2-3 attacks a week, lasting from hours to even days at a time. Some migraines are also experienced fairly infrequently, from months to even years, and may present as fairly mild and short-lived in comparison.
