  • Smaller pupil in one eye
  • Red ear
  • Blocked or runny nose

The episodes usually last between 15 minutes up to 3 hours and occur between 1-8 times throughout the day.

When to seek medical care

A doctor should be consulted as soon as possible upon the first episode of a possible cluster headache. The doctor will ask about the symptoms and tests are carried out.

A brain scan is required in some individuals to rule out other conditions that have similar symptoms to cluster headaches.

If diagnosed with cluster headaches, a specialist should be seen such as a neurologist regarding suitable treatment options.

Management

Cluster headaches are not dangerous but can cause significant discomfort and drastically affect the quality of life. With this in mind, it is vital to consult a doctor so that effective treatment options can be given.

The episodes could not be treated using over-the-counter pain medications such as paracetamol since they are slow to take any effect.

The 3 main treatments to provide pain relief once the episodes start include the following:

  • Sumatriptan injections are usually given 2 times a day
  • Oxygen therapy involves breathing in pure oxygen via a mask
  • Sumatriptan or zolmitriptan nasal spray can be used by those who do not want injections

It is important to note that these treatments typically relieve the pain of cluster headaches within 15-30 minutes.
