Cluster headache is a periodic, intense, sharp, burning and explosive pain that begins suddenly on one side of the head and tends to get worse quickly, reaching its peak within 10 minutes.
Knowing that you’re going to experience such a painful headache can cause extremely poor mental health.
Dr Brewer explained: “Although sufferers are perfectly well in between attacks, the pain is so severe that many live in fear of the next one occurring.”
However, it is important to note that some cluster sufferers may experience migraines and other types of headache when their cluster episode is over - they may never have a day free of headaches.
What causes cluster headaches?
Experts don’t know what causes cluster headaches but it involves the over-activation of a part of the brain, according to Dr Brewer.
