Symptoms of cluster headache typically set in at a particular time of the day, usually at the same time each night or in the early morning. They also occur at the same time of the year (usually during spring or autumn.).
Cluster headache has a cyclical pattern in which the headaches occur periodically alternating with periods of remissions during which you feel no headache. Along with the headache pain, there are other associated symptoms.
You should know that the cluster headache differs from migraine in its symptoms. A migraine headache is accompanied by nausea, sensitivity to light, and vomiting, whereas a person with cluster headache will experience symptoms of watery eyes and running nose.
The pain of cluster headache
Fortunately, the cluster headache is the least common type of headache. Its pain is probably the worst pain you can experience – much worse than a migraine headache. It usually reaches its peak within the first five to ten minutes of its onset.
The headache is one-sided and stays on the same side during future attacks too, switching to the other side during subsequent attacks in only 15% of the cases.
Within 5 to 10 minutes of onset, the headache pain reaches its peak. The headache pain is of a piercing type (often referred to as ice-pick pain) and may be constant or throbbing.
The patient is unable to sit still and usually paces around during the cluster attack. Once the headache starts to subside, the other accompanying symptoms described below disappear within minutes.
During a cluster period, smoking tobacco and drinking alcohol can trigger a cluster headache attack.
However, during the period of remission, both these will not give you a headache.
Location of cluster headache pain
The cluster headache pain is situated in the eye region either in the eye or behind the eye and may radiate to the cheeks, temple, forehead, nose and the gums on the same side.
Duration and frequency of headache pain
During the “cluster period”, the headache may appear two to three times a day and this period can last for a period of two weeks to three months. Some individuals have known to experience cluster headaches even six times a day.
The headache may last for as short as 15 minutes to three hours or more – average being about 45 minutes.
Period of remissions may last for months or even years, which may again be followed by the cluster period. This reappearance of the cluster period can come without any warning signs.
Other symptoms of cluster headache
Other symptoms include
- Lacrimation (teary eye)
- Nasal congestion or a running nose on the same side of the head
- The pupil of the eye on the side of the pain may constrict (shrink)
- The eye on the side of the pain may become red and swollen.
- Drooping of the eyelid on the same side of headache
- There may be sweating of the face and the facial skin becomes pale.
- Bulging and pulsating temporal artery on the side of the pain
The doctor diagnoses this headache from its symptoms and treatment is given mainly to control the symptoms of the patient. There is no permanent cure.
