Excruciating Agony: A Personal Fight Against the Enigmatic Pain of Cluster Headache Syndrome

It was a gloomy weekday morning in the autumn of 2016. I was working as a teacher, trying to settle a new group of students, when a intense pain bloomed behind my one eye. This was followed by rapid shocks, similar to lightning bolts. As each class progressed, the pain subsided and then returned with increased intensity. Multiple times that day I handed over a colleague with activities and ran to the staff bathroom to douse my face with cold water. I tried paracetamol, but the agony remained unbearable.

The attacks returned frequently that fall, and once more in the spring, soon forming an yearly pattern. The autumn months were the worst, then February and March. I could predict the pattern: aura in the morning, early twinges on the train, full-on pain in class by mid-morning. In late 2019, a doctor eventually referred me to a specialist and I was diagnosed with cluster headache disorder.

Cluster headaches often begin with severe pain behind a single eye that lasts up to several hours.

About 1 in 1000 individuals suffer by the disorder, and males are more often affected. Attacks typically begin with abrupt, excruciating pain focused on one eye that reaches its peak within a short time and continues for as long as three hours. Attacks occur in cycles, every day or multiple times a day, and are accompanied by tearing eyes, sagging eyelids or face sweating. I have the episodic form, which arrives in periodic cycles; some patients have chronic attacks, defined by the absence of extended symptom-free periods.

What connects sufferers is the severity. One research paper rated the sensation at 9.7 out of 10, higher than broken bones or other conditions. Another discovered a significant percentage of cluster patients experienced suicidal thoughts amid bouts; the number dropped to 4% when they were not in pain.

One patient, in her seventies, a long-term patient from Wales, finds this understandable. Her attacks started when she was two. “I would hurl myself on the floor and hit my head. That was attributed to being a difficult child,” she says. Her symptoms worsened through her youth. Drinking in her adolescence, similar to many causes, made things worse. After having alcohol at her school leaving party, she remembers barely being able to see on the transport home.

Her relatives often mistook her episodes as intoxicated behavior. Understanding eventually came from her parent and then from her partner, Rod. “I was very lucky to find such an exceptional person,” she says. Hobbs took office work after relocating, but often concealed her illness. She was dismissed from one job, partly due to absences during episodes. Her breakthrough identification came in the early 2000s at a specialist neurology center.

Nevertheless, the failure to plan life around erratic attacks took its effect. She particularly hated being unable to plan outings, being seen as flaky as a co-worker, and even having to be looked after by her family during the incapacitation caused by the most severe episodes. “It steals from you of the small liberties we don't appreciate 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 history. “The earliest account of headache comes by way of the Mesopotamians in antiquity,” write authors in a book on the subject. They linked the disease to an malevolent spirit who attacked his victims' heads.

Historical healing texts suggest unusual remedies for what modern observers would classify as a migraine. In the middle ages, severe headache was recognised as a separate condition, with therapies including herbal concoctions to other, more folk cures.

It was a European physician who provided the first detailed description of a cluster headache. In his medical observations, he describes a patient “suffering with a very intense headache occurring and disappearing each day at fixed hours”.

The disorder were only officially recognised by global medical societies in 1988. From the mid-20th century 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 specialists in diagnosing the disorder explain this.

In the late 1990s, scientists published the results of a research project for which they had triggered attacks in patients and monitored the episodes in a imaging machine. The results, published in a prominent medical publication, showed activation of the hypothalamus, which is in charge for human circadian rhythm, when patients were in discomfort, and a reduction when they recovered.

Despite such advances, identification remains delayed. Jamie Charteris's attacks started in 1986 and felt like “a balloon being inflated behind my one eye”. GPs thought he had sinus problems; he underwent multiple surgeries before finally being correctly identified in recently, after a doctor looked up his symptoms.

Neurologists say wait times in diagnosis and managing occur because patients are rarely seen mid-attack. “You're exhausted and low, but not in severe pain,” one says. He works by eliminating other common headache conditions, such as migraine, before diagnosing cluster headaches. A thorough patient history is crucial: on which part of the head do signs occur? For how long? What season? Are there precipitating factors, such as alcohol? Specific features such as tearing, drooping eyelids and stuffy nose help confirm the diagnosis. Once diagnosed, patients may be sent to dedicated centers. But a lot of first arrive to emergency rooms or are given unsuitable therapies.

Dorothy Chapman, 78, has suffered from cluster headaches for most of her adult life, although she hasn't had an episode since 2016. When she was in her 20s, she had her molars extracted because dentists misinterpreted her symptoms. She thinks the dental profession still need greater awareness. When another patient sought help from a charity, it was Chapman who responded. I remember calling a helpline during an bout in 2021; a calm volunteer guided me through oxygen treatment and drugs until the episode eased.

National guidelines on management advise that patients are offered high-dose oxygen therapy and/or a specific medication delivered by nasal spray. No tablets or opioids should be used. Preventive options include verapamil, which reportedly helps manage the bouts of some people.

But consultant specialists believe the official guidelines need revising to reflect a more defined clinical pathway and help general practitioners avoid incorrect prescriptions. For episodic patients, the treatment window is everything: “The length of the bout dictates the treatment.” Short bouts with infrequent episodes are handled with acute treatment alone. More prolonged or more intense bouts require preventative medications such as verapamil, sometimes paired with corticosteroids. Many patients also receive a nerve block injection during a cycle – an procedure into the side of the head where the discomfort is that decreases nerve signals.

The national guidelines need updating to reflect a
