Full-Blown Agony: A Personal Struggle With the Enigmatic Pain of Cluster Headache Syndrome

It was a dreary weekday morning in the autumn of 2016. I was working as a educator, attempting to manage a new group of students, when a sudden pain sprang behind my right eye. This was followed by rapid stabs, like electric shocks. As each class came and went, the pain subsided and then came back with increased force. Four times that day I handed over a colleague with worksheets and ran to the staff bathroom to douse my face with cold water. I tried aspirin, but the pain remained unbearable.

The headaches appeared repeatedly that fall, and once more in spring, soon forming an yearly cycle. September and October were the worst, then the late winter. I could anticipate the routine: aura in the morning, early twinges on the train, full-blown pain in the classroom by mid-morning. In 2019, a GP finally sent me to a specialist and I was given a diagnosis with cluster headaches.

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

About 1 in 1000 individuals are affected by the disorder, and men are more frequently diagnosed. Cluster headaches typically begin with sudden, excruciating agony around one eye that reaches its peak within minutes and continues for up to three hours. Episodes occur in cycles, daily or several times a day, and are accompanied by red or watery eyes, sagging eyelids or facial perspiration. There exists an episodic type, which arrives in periodic cycles; some patients have continuous attacks, defined by the absence of extended pain-free periods.

What unites patients is the intensity. One research paper rated the pain at 9.7 10, more severe than broken bones or pancreatitis. A separate found a significant percentage of cluster headache patients experienced suicidal thoughts amid attacks; the number fell to four percent when they were not in pain.

One patient, 74, a chronic patient from Pembrokeshire, isn't surprised. Her attacks started when she was a toddler. “I would throw myself on the ground and hit my head. That was put down to being spoiled,” she says. Her symptoms worsened through childhood. Drinking in her teens, similar to several causes, made things worse. After drinking alcohol at her graduation party, she remembers barely being able to see on the transport home.

Her relatives often mistook her attacks as drunken episodes. Support eventually came from her father and then from her husband, Rod. “I was very lucky to find such an exceptional person,” she says. Hobbs took office work after relocating, but often hid her illness. She was fired from one job, partly due to absences during attacks. Her definitive identification came in the early 2000s at a national hospital.

Nevertheless, the failure to plan life around unpredictable pain took its effect. She particularly hated being unable to plan outings, being seen as flaky as a co-worker, and even having to be cared for by her family during the paralysis caused by the most severe episodes. “It robs you of the small liberties we don't value until they're gone,” she says. She remembers winning tickets for a significant concert, only to have an attack inside a portable toilet.

Headaches have been described across the ages. “The first account of headache comes by way of the ancient civilizations in 4000BC,” write authors in a book on the topic. They attributed the disease to an malevolent entity who afflicted his sufferers' heads.

Ancient medical texts suggest unusual remedies for what some experts would classify as a migraine. In the medieval times, severe headache was recognised as a distinct disorder, with therapies ranging from bloodletting to other, more superstitious cures.

It was a Dutch doctor who provided the first comprehensive description of a cluster headache. In his writings, he speaks of a patient “afflicted with a very intense headache happening and disappearing daily at fixed hours”.

Cluster headaches were only officially recognised by global medical committees in the late 1980s. From the 1960s to the 1990s, they were believed to be caused by a issue with a key artery which delivers blood to the brain. Leading experts in treating the condition explain this.

In 1998, scientists released the findings of a research project for which they had induced cluster headaches in patients and observed the episodes in a brain scanner. The results, published in a major medical publication, showed increased activity of the hypothalamus, which is responsible for human circadian rhythm, when patients were in pain, and a deactivation when they felt better.

Despite such progress, identification remains delayed. Jamie Charteris's symptoms started in the 1980s and felt like “a modelling balloon being inflated behind my left eye”. GPs thought he had a sinus issue; he had four surgeries before finally being diagnosed in 2014, after a doctor looked up his symptoms.

Neurologists say wait times in diagnosis and managing happen because patients are rarely seen during an episode. “You're exhausted and depressed, but not in agony,” a doctor says. He works by eliminating other primary headache conditions, such as tension-type headache, before diagnosing the disorder. A thorough history is crucial: on which side do symptoms occur? For how long? What time of year? Are there triggers, such as certain foods? Certain characteristics such as tearing, sagging eyelids and nasal congestion help verify the diagnosis. Once identified, patients may be sent to specialist centers. But a lot of first go to emergency rooms or are given unsuitable therapies.

A charity trustee, 78, has suffered from cluster headaches for the majority of her life, although she hasn't had an attack since 2016. When she was in her twenties, she had her molars pulled because dental professionals misunderstood her pain. She believes the dental profession still need much more awareness. When another patient sought help from a support group, it was Chapman who replied. The author recalls calling a support line during an attack in early 2021; a reassuring advisor talked them through oxygen treatment and medication until the episode passed.

Official guidance on treatment recommend that patients are offered high-flow oxygen therapy and/or a anti-migraine medication administered by injection. No tablets or opioids should be used. Prophylactic choices include a blood pressure medication, which apparently soothes the attacks of some individuals.

But consultant specialists believe the official guidelines need updating to reflect a clearer clinical pathway and help general practitioners avoid misprescribing. For episodic patients, the treatment window is everything: “The duration of the cycle dictates the treatment.” Short cycles with occasional attacks are handled with acute therapy only. More prolonged or more intense bouts require preventives such as verapamil, sometimes combined with steroids. A significant number of patients also receive a nerve block injection during a cycle – an injection into the area of the head where the pain is that decreases nerve signals.

The official guidance need revising to reflect a
