Full-Blown Agony: My Battle Against the Puzzling Suffering of Cluster Headaches

It was a gloomy Monday in the morning in September 2016. I worked as a educator, attempting to manage a new class, when a sudden pain erupted behind my one eye. This was followed by quick shocks, reminiscent of lightning bolts. As the school day progressed, the discomfort eased and then came back with increased intensity. Multiple times that day I handed over a teaching assistant with worksheets and hurried to the school bathroom to douse my face with cold water. I tried ibuprofen, but the pain remained unrelenting.

The headaches returned repeatedly that autumn, and once more in the spring, soon establishing an annual cycle. September and October were the worst, then the late winter. I could predict the routine: a warning sensation in the morning, early twinges on the commute, full-blown pain in the classroom by mid-morning. In 2019, a GP finally sent me to a neurologist and I was diagnosed with cluster headache disorder.

This condition often begin with intense pain around one eye that persists for three hours.

Approximately 1 in 1000 individuals are affected by the disorder, and males are more frequently diagnosed. Cluster headaches usually begin with abrupt, excruciating agony focused on one eye that peaks within minutes and continues for up to three hours. Episodes come in clusters, every day or multiple times a day, and are associated with tearing eyes, drooping eyelids or facial sweating. There exists the episodic form, which arrives in periodic cycles; others have continuous cluster headaches, defined by the absence of long pain-free periods.

What unites sufferers is the severity. One research paper scored the sensation at 9.7 10, more severe than bone fractures or other conditions. A separate found a significant percentage of cluster headache patients reported suicidal thoughts amid bouts; the number dropped to four percent when they were pain-free.

One patient, in her seventies, a chronic patient from Pembrokeshire, isn't surprised. Her episodes began when she was a toddler. “I would throw myself on the floor and bang my head. That was attributed to being spoiled,” she says. Her condition deteriorated through her youth. Alcohol in her adolescence, similar to many triggers, made things worse. After drinking alcohol at her school leaving party, she recalls hardly being able to see on the bus home.

Her relatives often interpreted her episodes as intoxicated episodes. Support eventually came from her parent and then from her partner, Rod. “I was very fortunate to find such an understanding person,” she says. Hobbs found office work after relocating, but often hid her condition. She was fired from one job, in part due to time off during episodes. Her definitive identification came in 2002 at a specialist neurology center.

Still, the inability to plan life around erratic pain took its toll. She especially hated being unable to plan social events, being seen as flaky as a colleague, and even having to be looked after by her family during the incapacitation caused by the most severe episodes. “It robs you of the simple liberties we don't value until they're gone,” she says. She remembers obtaining tickets for a significant concert, only to have an episode inside a facility.

Headaches have been documented across the ages. “The earliest account of headache originates from the Mesopotamians in antiquity,” write authors in a book on the subject. They attributed the ailment to an malevolent spirit who attacked his sufferers' heads.

Ancient medical texts propose unusual treatments for what some observers would describe as a migraine. In the middle ages, migraine was recognised as a separate condition, with therapies including herbal concoctions to other, more folk remedies.

It was a European physician who provided the initial detailed description of a cluster headache. In his writings, he speaks of a patient “suffering with a very severe headache occurring and disappearing each day at specific hours”.

Cluster headaches were only officially classified by international headache committees in the late 1980s. From the 1960s to the 1990s, they were believed to be caused by a problem with a key blood vessel which supplies blood to the brain. Leading specialists in treating the disorder explain this.

In the late 1990s, scientists released the findings of a research project for which they had triggered cluster headaches in patients and observed the attacks in a brain scanner. The results, featured in a prominent medical publication, showed activation of the a brain region, which is responsible for human circadian rhythm, when patients were in pain, and a deactivation when they felt better.

Despite such progress, diagnosis remains slow. One man's symptoms began in 1986 and felt like “a modelling balloon being blown up behind my one eye”. Doctors thought he had sinus problems; he underwent multiple surgeries before finally being correctly identified in 2014, after a doctor researched his complaints.

Neurologists say delays in diagnosis and treatment happen because patients are seldom seen mid-attack. “You're exhausted and low, but not in agony,” one says. He works by eliminating other common headache conditions, such as tension-type headache, before diagnosing the disorder. A detailed history is crucial: on which side do symptoms occur? For how long? What season? Are there triggers, such as alcohol? Certain features such as tearing, drooping eyelids and stuffy nose help verify cluster headaches. Once identified, patients may be sent to dedicated centers. But a lot of first arrive to emergency rooms or are given inadequate therapies.

Dorothy Chapman, 78, has suffered from cluster headaches for most of her life, although she hasn't had an attack since recent years. When she was in her twenties, she had her teeth pulled because dentists misinterpreted her symptoms. She believes the dental profession still need greater awareness. When a sufferer sought help from a charity, it was Chapman who responded. I remember calling a support line during an bout in 2021; a reassuring volunteer guided me through oxygen therapy and medication until the episode eased.

Official guidance on management recommend that patients are offered high-dose oxygen and/or a specific drug administered by nasal spray. No tablets or opioids should be used. Prophylactic options include a blood pressure medication, which reportedly helps manage the attacks of some individuals.

But consultant neurologists believe the guidance need updating to reflect a clearer clinical pathway and help GPs avoid misprescribing. For episodic patients, the treatment window is critical: “The duration of the cycle determines the treatment.” Short bouts with occasional attacks are managed with abortive treatment alone. Longer or more intense bouts require preventives such as certain drugs, sometimes paired with corticosteroids. Many patients also receive a greater occipital nerve block during a cycle – an procedure into the side of the skull where the discomfort is that reduces nerve signals.

The national guidance need updating to reflect a
