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 and prevents you from carrying out normal activities.
Other symptoms commonly associated include: nausea, vomiting, increased sensitivity to light and sound– which is why many people with a migraine want to rest in a quiet, dark room. Some people also occasionally experience other symptoms, including: sweating, poor concentration, feeling very hot or cold, abdominal pain, diarrhoea.
