What is a Cluster Headache?
Cluster headaches are unilateral thus only affecting one side of the head. It has been noted that the headache can switch sides from time to time.
They start suddenly and the pain escalates fast into a severe pain compared to a knife stuck into the affected eye and near that temple.
The pain can last from a few minutes to sometimes 3 hours.
Cluster periods can last for a few weeks or months.
The eye becomes red and tears, the nose runs while congested, the face, hair, jaw and ear becomes sensitive and sometimes painful on the affected side.
The person experiencing a "Cluster attack" is agitated and cannot lie down or sit still. This results frequently in banging the head restless pacing and rocking to and fro.
This headache is known to wake the sufferer from sleep at regular times in the night.
