Full-Blown Agony: My Struggle With the Puzzling Suffering of Cluster Headaches
It began on a overcast Monday morning in the autumn of 2016. I was working as a teacher, trying to settle a new class, when a sudden pain erupted behind my right eye. It was followed by quick stabs, reminiscent of lightning bolts. As the school day progressed, the discomfort subsided and then returned with increased force. Multiple times that day I left a teaching assistant with worksheets and hurried to the school bathroom to douse my face with cold water. I tried aspirin, but the pain remained unbearable.
The attacks appeared frequently that fall, and once more in spring, soon establishing an yearly cycle. The autumn months were the worst, then the late winter. I could predict the pattern: a warning sensation in the shower, early pangs on the commute, full-on pain in the classroom by mid-morning. In late 2019, a doctor eventually sent me to a neurologist and I was given a diagnosis with cluster headaches.
This condition typically begin with severe pain around one eye that lasts up to three hours.
Approximately 1 in 1000 individuals are affected by the disorder, and males are more often affected. Cluster headaches typically begin with abrupt, excruciating agony around one 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 accompanied by red or watery eyes, sagging eyelids or face sweating. I have an episodic type, which arrives in periodic cycles; others have continuous attacks, characterized by the lack of extended symptom-free periods.
What connects sufferers is the severity. One research paper scored the sensation at 9.7 out of 10, higher than bone fractures or pancreatitis. A separate found a significant percentage of cluster patients experienced thoughts of self-harm amid bouts; the figure fell to four percent when they were not in pain.
Val Hobbs, 74, a long-term patient from Wales, isn't surprised. Her episodes started when she was a toddler. “I would hurl myself on the ground and hit my head. That was put down to being a difficult child,” she says. Her condition worsened through her youth. Alcohol in her teens, like many triggers, made things more intense. After drinking sherry at her graduation party, she recalls hardly being able to see on the transport home.
Her family often mistook her attacks as intoxicated behavior. Understanding finally came from her parent and then from her partner, Rod. “I was very fortunate to find such an understanding person,” she says. Hobbs took clerical work after moving, but often hid her condition. She was dismissed from one job, in part due to time off during episodes. Her definitive identification came in 2002 at a specialist neurology center.
Still, the failure to plan life 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 looked after by her family during the paralysis caused by the most severe episodes. “It steals from you of the small freedoms we don't appreciate until they're gone,” she says. She remembers winning tickets for a major concert, only to have an episode inside a portable toilet.
Headaches have been described throughout the ages. “The first description of headache originates from the ancient civilizations in 4000BC,” write authors in a publication on the subject. They linked the ailment to an malevolent entity who attacked his victims' heads.
Historical medical texts suggest unusual remedies for what some observers would classify as a headache disorder. In the medieval times, migraine was identified as a separate disorder, with therapies ranging from bloodletting to other, more folk cures.
It was a European doctor who provided the first comprehensive description of a cluster-type attack. In his writings, he describes a patient “suffering with a very severe headache occurring and disappearing daily at specific hours”.
Cluster headaches were only officially recognised by global headache committees in the late 1980s. From the 1960s to the late 1990s, they were believed to be caused by a problem with a major blood vessel which supplies blood to the head. Prominent experts in diagnosing the condition note this.
In 1998, scientists released the findings of a research project for which they had triggered attacks in patients and monitored the attacks in a brain scanner. The data, published in a major journal, showed increased activity of the a brain region, which is responsible for human circadian rhythm, when patients were in discomfort, and a deactivation when they recovered.
Despite such advances, identification remains delayed. One man's attacks started in the 1980s and felt like “a modelling balloon being inflated behind my one eye”. GPs thought he had a sinus issue; he underwent four surgeries before finally being correctly identified in 2014, after a doctor researched his complaints.
Specialists say wait times in diagnosing and treatment occur because patients are seldom seen during an episode. “You're tired and low, but not in agony,” one says. He works by eliminating other common headache conditions, such as migraine, before diagnosing the disorder. A detailed history is crucial: on which side do signs occur? For how much time? What time of year? Are there precipitating factors, such as alcohol? Specific characteristics such as tearing, sagging eyelids and nasal congestion help confirm cluster headaches. Once diagnosed, patients may be referred to specialist centers. But many first go to emergency rooms or are given unsuitable treatments.
A charity trustee, in her late seventies, has suffered from the condition for the majority of her life, although she hasn't had an attack since 2016. When she was in her 20s, she had her teeth extracted because dentists misinterpreted her pain. She believes the dental profession still need greater education. When another patient sought help from a charity, it was Chapman who replied. I remember calling a support line during an bout in 2021; a reassuring advisor talked them through oxygen treatment and drugs until the attack passed.
National guidance on management advise that sufferers are offered high-dose oxygen and/or a specific drug delivered by nasal spray. No tablets or opioids should be used. Preventive choices include verapamil, which reportedly soothes the bouts of well-known individuals.
But consultant neurologists argue the official guidelines need updating to reflect a clearer clinical pathway and help GPs avoid incorrect prescriptions. For periodic patients, timing is critical: “The duration of the cycle dictates the treatment.” Short cycles with infrequent episodes are managed with acute treatment only. Longer or more severe periods require preventives such as certain drugs, sometimes paired with steroids. Many patients also receive a nerve block injection during a cycle – an injection into the side of the head where the pain is that decreases nerve activity.
The official guidelines need revising to reflect a
