2. Cluster headaches affect 0.05 per cent of the population in any given year. This compares to 12 per cent of the population who get migraines. Men are three to four times more likely than women to have cluster headaches. Oxygen is used in many instances to help relieve the pain.
3. They are also known as “suicide headaches”. Patients often self-harm during attacks and suicidal thoughts are common. There is a case cited in medical publications of a man who poured boiling water from a kettle over his head during a cluster headache.
