Full-Blown Agony: My Battle Against the Enigmatic Suffering of Cluster Headache Syndrome

It began on a gloomy weekday in the morning in September 2016. I was working as a educator, trying to settle a new class, when a sudden pain sprang behind my one eye. It was followed by quick shocks, like lightning bolts. As the school day came and went, the discomfort eased and then returned with increased force. Multiple times that day I left a teaching assistant with activities and hurried to the staff bathroom to soak my face with cool water. I took paracetamol, but the agony remained unbearable.

The headaches returned frequently that autumn, and once more in the spring, soon establishing an yearly cycle. The autumn months were the worst, then February and March. I could anticipate the routine: a warning sensation in the shower, early pangs on the commute, full-on pain in class by 9.30am. In late 2019, a doctor finally sent me to a specialist and I was diagnosed with cluster headaches.

This condition typically begin with severe discomfort around a single eye that lasts for three hours.

About one in 1,000 individuals are affected by the disorder, and males are more often affected. Cluster headaches typically start with sudden, severe pain focused on a single eye that reaches its peak within minutes and lasts for as long as three hours. Episodes come in clusters, daily or multiple times a day, and are associated with tearing eyes, sagging eyelids or facial perspiration. There exists the episodic form, which occurs in seasonal cycles; some patients have continuous cluster headaches, characterized by the absence of long symptom-free periods.

What unites patients is the intensity. One research paper scored the pain at 9.7 10, more severe than bone fractures or other conditions. Another discovered a significant percentage of cluster patients reported suicidal thoughts during attacks; the number fell to four percent when they were pain-free.

One patient, 74, a chronic sufferer from Pembrokeshire, isn't surprised. Her attacks started when she was a toddler. “I would hurl myself on the floor and bang my head. That was put down to being a difficult child,” she says. Her condition worsened through childhood. Alcohol in her adolescence, similar to several triggers, made things worse. After drinking alcohol at her graduation party, she recalls hardly being able to see on the bus home.

Her family often mistook her episodes as intoxicated behavior. Support eventually came from her parent and then from her partner, her spouse. “I was very fortunate to find such an understanding person,” she says. Hobbs found clerical work after moving, but often concealed her condition. She was dismissed from one job, partly due to absences during attacks. Her breakthrough identification came in 2002 at a national neurology center.

Nevertheless, the failure to plan daily activities around erratic attacks took its effect. She especially hated being unable to plan outings, being seen as flaky as a colleague, and even having to be cared for by her children during the paralysis caused by the most severe episodes. “It robs you of the small liberties we don't appreciate until they're gone,” she says. She recalls winning tickets for a significant concert, only to have an attack inside a portable toilet.

Headaches have been described throughout the ages. “The first description of headache originates from the Mesopotamians in 4000BC,” write authors in a publication on the subject. They attributed the ailment to an malevolent entity who attacked his sufferers' heads.

Historical medical texts suggest bizarre remedies for what modern observers would describe as a headache disorder. In the middle ages, migraine was identified as a separate condition, with treatments ranging from herbal concoctions to other, more folk cures.

It was a Dutch physician who provided the initial detailed account of a cluster headache. In his writings, he speaks of a patient “suffering with a very severe headache happening and disappearing daily at fixed hours”.

The disorder were only officially recognised by global medical committees in the late 1980s. From the 1960s to the late 1990s, they were believed to be caused by a issue with a major blood vessel which supplies blood to the brain. Leading experts in diagnosing the disorder explain this.

In 1998, scientists released the findings of a study for which they had induced cluster headaches in patients and monitored the episodes in a brain scanner. The data, published in a prominent medical publication, showed increased activity of the a brain region, which is in charge for human circadian rhythm, when patients were in pain, and a deactivation when they recovered.

Despite such advances, diagnosis remains slow. One man's symptoms started in 1986 and felt like “a modelling balloon being inflated behind my one eye”. GPs thought he had sinus problems; he had multiple surgeries before eventually being correctly identified in recently, after a doctor looked up his complaints.

Specialists say delays in diagnosis and treatment occur because patients are rarely seen during an episode. “You're tired and depressed, but not in severe pain,” a doctor says. He proceeds by eliminating other primary headache conditions, such as migraine, before diagnosing the disorder. A detailed patient history is essential: on which part of the head do symptoms appear? For how long? What season? Are there precipitating factors, such as alcohol? Certain features such as redness, drooping eyelids and nasal congestion help verify the diagnosis. Once identified, patients may be referred to dedicated clinics. But many first arrive to A&E or are given unsuitable therapies.

A charity trustee, 78, has suffered from cluster headaches for most of her adult life, although she has been free from an attack since recent years. When she was in her twenties, she had her teeth extracted because dentists misinterpreted her symptoms. She thinks the dental profession still need greater education. When another patient sought help from a support group, it was she who replied. The author recalls calling a support line during an attack in 2021; a calm advisor guided them through oxygen therapy and drugs until the episode passed.

National guidance on management advise that sufferers are offered high-flow oxygen therapy and/or a specific medication administered by nasal spray. No oral painkillers or opioids should be used. Prophylactic choices include verapamil, which reportedly helps manage the attacks of well-known individuals.

But consultant neurologists believe the official guidelines need updating to reflect a more defined clinical process and help general practitioners avoid misprescribing. For periodic patients, timing is everything: “The length of the cycle determines the treatment.” Brief cycles with occasional attacks are handled with acute therapy alone. More prolonged or more intense bouts require preventives such as certain drugs, sometimes paired with corticosteroids. Many patients also receive a nerve block injection during a bout – an injection into the side of the skull where the discomfort is that reduces nerve activity.
