Full-Blown Agony: A Personal Battle Against the Puzzling Suffering of Cluster Headache Syndrome

It began on a gloomy weekday in the morning in September 2016. I worked as a educator, trying to settle a new group of students, when a sudden pain sprang behind my right eye. This was followed by rapid shocks, reminiscent of lightning bolts. As each class progressed, the pain subsided and then came back with increased intensity. Four times that day I left a colleague with worksheets and ran to the staff bathroom to soak my face with cool water. I took paracetamol, but the agony remained unrelenting.

The attacks returned repeatedly that autumn, and again in the spring, soon establishing an yearly cycle. September and October were the worst, then the late winter. I could anticipate the routine: a warning sensation in the morning, early twinges on the train, full-on pain in class by 9.30am. In 2019, a GP eventually sent me to a specialist and I was diagnosed with cluster headache disorder.

Cluster headaches often start with severe pain around a single eye that persists up to several hours.

Approximately one in 1,000 people suffer by the disorder, and men are more often affected. Cluster headaches typically begin with sudden, excruciating agony focused on a single eye that peaks within minutes and continues for up to three hours. Episodes occur in cycles, every day or multiple times a day, and are accompanied by red or watery eyes, drooping eyelids or facial sweating. I have an episodic type, which occurs in periodic bouts; some patients have continuous attacks, characterized by the absence of long symptom-free periods.

What unites sufferers is the severity. One study rated the sensation at 9.7 out of 10, more severe than broken bones or pancreatitis. Another found a significant percentage of cluster patients experienced thoughts of self-harm amid attacks; the figure fell to four percent when they were pain-free.

One patient, in her seventies, a chronic patient from Wales, isn't surprised. Her attacks began when she was a toddler. “I would hurl myself on the floor and bang my head. That was put down to being spoiled,” she says. Her condition worsened through her youth. Alcohol in her teens, similar to several causes, made things worse. After drinking alcohol at her school leaving party, she remembers hardly being able to see on the bus home.

Her family often interpreted her attacks as drunken episodes. Understanding eventually came from her parent and then from her husband, her spouse. “I was very fortunate to find such an understanding person,” she says. Hobbs took office work after relocating, but often concealed her illness. She was dismissed from one job, partly due to time off during episodes. Her definitive diagnosis came in 2002 at a specialist neurology center.

Still, the failure to plan daily activities around erratic pain took its toll. She especially hated being unable to plan social events, being seen as flaky as a co-worker, and even having to be looked after by her family during the incapacitation caused by the worst episodes. “It robs you of the simple freedoms we don't appreciate until they're gone,” she says. She remembers winning tickets for a significant concert, only to have an episode inside a facility.

Headaches have been documented throughout the ages. “The earliest account of headache originates from the Mesopotamians in 4000BC,” write authors in a publication on the topic. They attributed the ailment to an evil spirit who attacked his victims' heads.

Ancient medical texts propose bizarre treatments for what modern observers would describe as a headache disorder. In the medieval times, migraine was recognised as a separate disorder, with therapies ranging from bloodletting to other, more superstitious remedies.

It was a European doctor who provided the first comprehensive description of a cluster headache. In his writings, he describes a patient “suffering with a very severe headache occurring and vanishing daily at fixed hours”.

The disorder were only formally recognised by global medical committees in the late 1980s. From the mid-20th century to the late 1990s, they were thought to be caused by a issue with a major blood vessel that supplies blood to the brain. Prominent experts in treating the disorder explain this.

In 1998, researchers released the results of a study for which they had triggered attacks in patients and monitored the attacks in a imaging machine. The data, published in a major medical publication, showed increased activity of the a brain region, which is responsible for human circadian rhythm, when patients were in discomfort, and a reduction when they felt better.

In spite of such advances, identification remains slow. Jamie Charteris's symptoms started in 1986 and felt like “a modelling balloon being inflated behind my left eye”. Doctors thought he had a sinus issue; he had multiple surgeries before eventually being correctly identified in recently, after a doctor looked up his complaints.

Specialists say wait times in diagnosing and treatment happen because patients are seldom seen during an episode. “You're tired and depressed, but not in severe pain,” a doctor says. He proceeds by eliminating other primary head pain conditions, such as tension-type headache, before confirming the disorder. A detailed patient history is essential: on which side do symptoms appear? For how much time? What season? Are there precipitating factors, such as alcohol? Certain characteristics such as tearing, sagging eyelids and nasal congestion help verify cluster headaches. Once diagnosed, patients may be sent to specialist centers. But a lot of first arrive to emergency rooms or are given inadequate treatments.

A charity trustee, 78, has experienced the condition for most of her life, although she hasn't had an attack since recent years. When she was in her twenties, she had her molars pulled because dentists misunderstood her pain. She thinks the dental profession still need much more education. When another patient sought help from a charity, it was Chapman who responded. I remember calling a helpline during an bout in 2021; a reassuring volunteer talked them through oxygen therapy and medication until the attack passed.

Official guidelines on management recommend that sufferers are offered high-flow oxygen and/or a anti-migraine medication delivered by nasal spray. No oral painkillers or opioids should be used. Preventive choices include verapamil, which apparently helps manage the bouts of some people.

But consultant specialists argue the guidance need revising to reflect a more defined clinical process and help GPs avoid misprescribing. For periodic patients, the treatment window is everything: “The length of the cycle dictates the treatment.” Brief cycles with occasional attacks are handled with acute therapy alone. Longer or more intense bouts require preventives such as certain drugs, sometimes paired with steroids. A significant number of 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 signals.

The national guidance need updating to reflect a
