Excruciating Pain: A Personal Battle With the Enigmatic Suffering of Cluster Headaches

It was a gloomy Monday in the 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 right eye. This was followed by rapid jolts, similar to electric shocks. As the school day progressed, the pain eased and then came back with greater intensity. Four times that day I handed over a colleague with worksheets and ran to the school bathroom to soak my face with cold water. I tried aspirin, but the agony remained unrelenting.

The headaches appeared repeatedly that autumn, and again in the spring, soon forming an annual cycle. The autumn months were the worst, then the late winter. I could anticipate the pattern: aura in the shower, early twinges on the train, full-blown agony in class by 9.30am. In 2019, a doctor eventually referred me to a specialist and I was given a diagnosis with cluster headache disorder.

Cluster headaches typically begin with intense discomfort around a single eye that lasts up to three hours.

About one in 1,000 individuals are affected by the condition, and males are more frequently diagnosed. Attacks typically begin with sudden, severe agony focused on a single eye that peaks within a short time and lasts for as long as three hours. Attacks occur in cycles, every day or several times a day, and are accompanied by tearing eyes, sagging eyelids or face sweating. There exists the episodic form, which arrives in periodic bouts; others have continuous cluster headaches, characterized by the absence of long pain-free periods.

What unites sufferers is the intensity. One research paper rated the pain at 9.7 10, higher than broken bones or other conditions. A separate discovered a significant percentage of cluster headache patients experienced thoughts of self-harm amid bouts; the number dropped to 4% when they were pain-free.

Val Hobbs, 74, a chronic patient from Wales, isn't surprised. Her episodes started when she was two. “I would hurl myself on the ground and hit my head. That was attributed to being spoiled,” she says. Her condition worsened through her youth. Alcohol in her adolescence, similar to several causes, made things more intense. After drinking alcohol at her school leaving party, she remembers barely being able to see on the bus home.

Her relatives often mistook her attacks as drunken behavior. Support eventually came from her parent and then from her partner, her spouse. “I was very lucky to find such an exceptional 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 attacks. Her breakthrough identification came in the early 2000s at a specialist neurology center.

Still, the failure to plan daily activities around erratic pain took its effect. She especially hated being unable to plan outings, being seen as unreliable as a co-worker, and even having to be cared for by her family during the paralysis caused by the most severe episodes. “It steals from you of the small freedoms we don't value until they're gone,” she says. She recalls obtaining tickets for a significant concert, only to have an episode inside a facility.

Headaches have been described across history. “The first account of headache originates from the ancient civilizations in antiquity,” write experts in a book on the subject. They linked the ailment to an evil entity who afflicted his victims' heads.

Ancient healing records suggest bizarre treatments for what modern observers would describe as a migraine. In the medieval times, severe headache was recognised as a separate condition, with treatments including herbal concoctions to other, more superstitious cures.

It was a Dutch doctor who provided the initial detailed description of a cluster-type attack. In his writings, he describes a patient “suffering with a very intense headache happening and vanishing each day at fixed hours”.

The disorder were only formally classified by international headache societies in 1988. From the 1960s to the late 1990s, they were believed to be caused by a issue with a key blood vessel which delivers blood to the brain. Leading specialists in diagnosing the condition note this.

In 1998, scientists published the findings of a research project for which they had induced cluster headaches in patients and monitored the attacks in a imaging machine. The data, featured in a prominent medical publication, showed increased activity of the a brain region, which is in charge for human sleep-wake cycles, when patients were in pain, and a reduction when they recovered.

In spite of such advances, diagnosis remains delayed. Jamie Charteris's symptoms began in 1986 and felt like “a modelling balloon being inflated behind my one eye”. GPs thought he had a sinus issue; he underwent four operations before finally being diagnosed in 2014, after a doctor researched his complaints.

Neurologists say delays in diagnosis and managing occur because patients are rarely seen mid-attack. “You're tired and depressed, but not in severe pain,” a doctor says. He proceeds by ruling out other primary headache conditions, such as migraine, before diagnosing cluster headaches. A thorough patient history is crucial: on which side do symptoms appear? For how long? What time of year? Are there precipitating factors, such as certain foods? Specific characteristics such as tearing, drooping eyelids and stuffy nose help verify cluster headaches. Once diagnosed, patients may be sent to dedicated centers. But many first arrive to A&E or are given unsuitable therapies.

Dorothy Chapman, in her late seventies, has experienced the condition for most of her life, although she hasn't had an attack since 2016. When she was in her twenties, she had her teeth extracted because dental professionals misinterpreted her symptoms. She thinks dentists still need much more awareness. When another patient sought help from a charity, it was Chapman who replied. The author recalls calling a support line during an bout in early 2021; a reassuring volunteer guided them through oxygen treatment and medication until the episode eased.

National guidelines on management advise that sufferers are offered high-flow oxygen and/or a specific medication delivered by nasal spray. No oral painkillers or opioids should be used. Preventive options include a blood pressure medication, which apparently helps manage the attacks of well-known individuals.

But consultant neurologists argue the guidance need revising to reflect a clearer clinical pathway and help GPs avoid misprescribing. For periodic patients, timing is everything: “The duration of the bout determines the approach.” Short cycles with occasional episodes are managed with abortive treatment alone. More prolonged or more severe periods require preventives such as verapamil, sometimes combined with corticosteroids. A significant number of patients also receive a nerve block injection during a bout – an procedure into the area of the skull where the pain is that reduces nerve activity.

The national guidelines need updating to reflect a
