A cluster headache is a relatively rare type of headache that starts suddenly and is characterised by excruciating pain in or around one eye. It usually lasts about 45 minutes and occurs at the same time each day for several weeks, until the "cluster period" ends.
Take action:
Consult your doctor if you think you may suffer from cluster headaches. Your description of your headaches will help your doctor make a diagnosis. The time and pattern of attacks are important, so keep a pain diary. During a cluster period, it is important to keep to your usual routine, stay calm, and stick to your sleep pattern. And don’t drink alcohol during this time.
