Cluster headache is a very painful form of headache, which most often affects men, these headaches appear to be localised in the eye, the temple, the forehead or the cheek region. The pain is severe and usually lasts 30 – 90 minutes.
It is called a cluster headache, because it usually happens in a series or sequence of painful episodes – often at the same time of day, days, weeks or months apart. Its causes are thought to include heavy drinking and smoking. Treatment largely consists of prevention, but many different types of medication are used, from oxygen inhalation, to steroids to opioids, among others. Recurring cluster headaches must be treated by a doctor.
