[…] Cluster headaches may go away completely (this is called going into remission) for months or years, but they can come back without any warning. […] Experts aren’t sure what causes cluster headaches. There’s evidence of a link to the hypothalamus, an area deep in your brain that controls things such as your body temperature, heart rate, and sleep cycles. […] Researchers do believe that the activation of a key „pathway” nerve is how the severe pain travels behind your eye, to your forehead, and jaw all on one side of your face.

• #5 Severe Headache: What is cluster headache and how is it different from migraine? | EBSCO

  https://www.ebsco.com/blogs/health-notes/severe-headache-pain-could-it-be-cluster-headache

  Cluster headache is an uncommon headache disease characterized by short-lasting headache attacks with severe unilateral pain in the trigeminal area. […] One of the classic TACs is cluster headache, where patients describe their pain as the most severe ever experienced. […] The unilateral headache pain associated with cluster headache is often confused with migraine. […] Cluster headache attacks are short but occur in clusters with multiple attacks over a period of four-12 weeks. […] Patients with cluster headache describe extremely painful unilateral headaches that are side-locked, lasting 15-180 minutes. […] The headache attacks are frequent (occurring once or several times per day), reaching a maximum pain intensity quickly and then stopping abruptly. […] Autonomic symptoms frequently occur on the same side of the headache pain and include swelling around the eye, sweating on the face and forehead, nasal congestion, runny nose, tearing, pupillary constriction, and eyelid droop.

  https://www.ncbi.nlm.nih.gov/books/NBK544241/

  Cluster headaches are the most common of the primary headache type known as trigeminal autonomic cephalgia. They are fairly rare, plaguing 0.1% of the population, making studying the disease process difficult at best. They are considered one of if not the most severe types of headaches, and so, despite their rarity, recognition and treatment are vital. […] Like other trigeminal autonomic cephalgias (TACs), cluster headache is a short-lasting unilateral headache with at least one autonomic symptom ipsilateral to the headache, such as lacrimation, nasal congestion, conjunctival injection, or aural fullness. The associated nasal congestion can sometimes lead to a misdiagnosis of „sinus headache,” and patients are often managed by decongestants, which are ineffective for cluster headaches. These headaches can occur every other day to eight times a day. They usually occur at approximately the same time of day, most often at night. Most patients are episodic, with daily attacks for weeks to months, followed by remission for months to years.

  The pain of cluster headache is maximal orbitally, supraorbitally, temporally or in any combination of these sites, but may spread to other regions. During the worst attacks, the intensity of pain is excruciating. Patients are usually unable to lie down, and characteristically pace the floor. Pain usually recurs on the same side of the head during a single cluster period. […] Age at onset is usually 20-40 years. For unknown reasons, men are afflicted three times more often than are women. […] Acute attacks involve activation in the region of the posterior hypothalamic grey matter. Cluster headache may be autosomal dominant in about 5% of cases. […] Some patients have been described who have both cluster headache and trigeminal neuralgia (sometimes referred to as cluster-tic syndrome). They should receive both diagnoses. The importance of this observation is that both conditions must be treated for the patient to become headache free.

  https://emedicine.medscape.com/article/1142459-clinical

  Attacks of cluster headache (CH) are typically short and occur with a clear periodicity, particularly during sleep or early morning hours, usually corresponding with onset of rapid eye movement (REM) sleep. Unlike migraine, CH is not preceded by aura and is not usually accompanied by symptoms such as nausea, vomiting, photophobia, or osmophobia. Typically, a patient experiences 12 cluster periods per year, each lasting 2 weeks to 3 months. […] The pain of CH is manifested as follows: Character – Excruciating, stabbing, sharp, and lancinating (as if the eye is being pushed out), rather than throbbing. Location Unilateral, in the periorbital, retro-orbital, or temporal regions, though pain sometimes radiates to the cheek, jaw, occipital, and nuchal regions; the pain tends to remain on the same side during the cluster period but in rare cases may switch sides. Distribution – First and second divisions of the trigeminal nerve; approximately 1820% of patients complain of pain in the extratrigeminal areas (eg, the back of the neck, along the carotid artery). Onset Sudden, peaking in 1015 minutes. Duration – 5 minutes to 3 hours per episode. Frequency – May occur 18 times a day for as long as 4 months (often nocturnal). Periodicity – Circadian regularity in 47%. Remission – Long symptom-free intervals occur in some patients; the length of these remissions averages 2 years but may range from 2 months to 20 years.

• #18 Cluster headache – Wikipedia

  https://en.wikipedia.org/wiki/Cluster_headache

  Cluster headaches are recurring bouts of severe unilateral headache attacks. The duration of a typical cluster headache ranges from about 15 to 180 minutes. About 75% of untreated attacks last less than 60 minutes. However, women may have longer and more severe cluster headaches. The onset of an attack is rapid and typically without an aura. Preliminary sensations of pain in the general area of attack, referred to as „shadows”, may signal an imminent cluster headache, or these symptoms may linger after an attack has passed, or between attacks. Though cluster headaches are strictly unilateral, there are some documented cases of „side-shift” between cluster periods, or, rarely, simultaneous (within the same cluster period) bilateral cluster headaches. […] The typical symptoms of cluster headache include grouped occurrence and recurrence (cluster) of headache attack, severe unilateral orbital, supraorbital and/or temporal pain. If left untreated, attack frequency may range from one attack every two days to eight attacks per day. Cluster headache attack is accompanied by at least one of the following autonomic symptoms: drooping eyelid, pupil constriction, redness of the conjunctiva, tearing, runny nose and less commonly, facial blushing, swelling, or sweating, typically appearing on the same side of the head as the pain. Similar to a migraine, sensitivity to light (photophobia) or noise (hyperacusis) may occur during a cluster headache. Nausea is a rare symptom although it has been reported.

• #52 Cluster headache – Wikipedia

  https://en.wikipedia.org/wiki/Cluster_headache

  Cluster headaches may occasionally be referred to as „alarm clock headache” because of the regularity of their recurrence. Cluster headaches often awaken individuals from sleep. Both individual attacks and the cluster grouping can have a metronomic regularity; attacks typically strike at a precise time of day each morning or night. The recurrence of headache cluster grouping may occur more often around solstices, or seasonal changes, sometimes showing circannual periodicity. Conversely, attack frequency may be highly unpredictable, showing no periodicity at all. These observations have prompted researchers to speculate an involvement or dysfunction of the hypothalamus. The hypothalamus controls the body’s „biological clock” and circadian rhythm. In episodic cluster headache, attacks occur once or more daily, often at the same time each day for a period of several weeks, followed by a headache-free period lasting weeks, months, or years. Approximately 10-15% of cluster headaches are chronic, with multiple headaches occurring every day for years, sometimes without any remission.

  Generally, cluster headache (CH) is a lifelong problem. Potential outcomes include recurrent attacks, prolonged remissions, and the possibility of transformation of an episodic cluster to a chronic cluster and vice versa. About 80% of patients with episodic CH maintain the episodic form of the disorder. In 4-13%, episodic CH eventually transforms into chronic CH. Intermediate (mixed) forms may also develop. Prolonged, spontaneous remissions occur in as many as 12% of patients, particularly in those with episodic CH. Chronic CH is more relentless and may persist in this form in as many as 55% of cases. Less frequently, chronic CH may remit into an episodic form.

  Cluster headache is a primary headache disorder affecting up to 0.1% of the population. Patients suffer from cluster headache attacks lasting from 15 to 180 min up to 8 times a day. The attacks are characterized by the severe unilateral pain mainly in the first division of the trigeminal nerve, with associated prominent unilateral cranial autonomic symptoms and a sense of agitation and restlessness during the attacks. […] The prognosis of cluster headache remains difficult to predict. Patients with episodic cluster headache can shift to chronic cluster headache and vice versa. Longitudinally, cluster headache tends to remit with age with less frequent bouts and more prolonged periods of remission in between bouts. […] The cluster headache attack clinical phenotype is similar between men and women. However, women with cluster headache tend to have more nausea and vomiting with their attacks.

  The duration, in which patients have cluster headache attacks, is called a bout, and this can range on average between 6 and 12 weeks. Patients with cluster headaches may experience bouts separated by months or even years of remission. […] The natural history of cluster headache is difficult to predict. In patients with initial ECH, 13% may subsequently develop CCH. On the contrary, 33% of patients with initial CCH may shift to the episodic pattern during the course of the disorder. Anecdotally, cluster headache tends to remit with age with less frequent bouts and more prolonged periods of remission between bouts.
