Excruciating Agony: A Personal Battle Against the Enigmatic Suffering of Cluster Headaches

It was a gloomy Monday in the morning in September 2016. I worked as a teacher, attempting to manage a new class, when a sharp sensation erupted behind my one eye. This was followed by quick stabs, reminiscent of electric shocks. As the school day progressed, the pain subsided and then returned with greater force. Multiple times that day I left a teaching assistant with worksheets and ran to the school bathroom to soak my face with cool water. I tried paracetamol, but the agony remained unrelenting.

The headaches returned frequently that fall, and once more in the spring, soon forming an annual cycle. The autumn months were the worst, then the late winter. I could anticipate the pattern: a warning sensation in the shower, early pangs on the commute, full-on agony in the classroom by 9.30am. In late 2019, a GP eventually sent me to a neurologist and I was given a diagnosis with cluster headaches.

This condition often begin with severe pain around one eye that persists for several hours.

About 1 in 1000 individuals suffer by the condition, and males are more often affected. Cluster headaches usually start with abrupt, excruciating agony focused on a single eye that peaks within a short time and lasts for up to three hours. Attacks occur in cycles, every day or multiple times a day, and are accompanied by tearing eyes, sagging eyelids or face sweating. There exists the episodic form, which occurs in periodic cycles; some patients have continuous attacks, characterized by the absence of extended pain-free periods.

What unites patients is the severity. One research paper scored the sensation at 9.7 10, more severe than bone fractures or other conditions. A separate found a significant percentage of cluster headache patients reported suicidal thoughts amid bouts; the figure dropped to 4% when they were not in pain.

One patient, 74, a long-term patient from Wales, finds this understandable. Her episodes began 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 condition worsened through her youth. Drinking in her adolescence, like several triggers, made things worse. After having alcohol at her school leaving party, she recalls barely being able to see on the bus home.

Her family often interpreted her attacks as intoxicated episodes. Support eventually came from her father and then from her partner, Rod. “I was very fortunate to find such an understanding person,” she says. Hobbs found clerical work after relocating, but often hid her condition. She was dismissed from one job, in part due to absences during attacks. Her definitive identification came in 2002 at a specialist hospital.

Nevertheless, the inability to plan daily activities around erratic attacks took its effect. She particularly hated being unable to plan social events, being seen as unreliable as a co-worker, and even having to be cared for by her children during the incapacitation 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 recalls winning tickets for a significant concert, only to have an episode inside a facility.

Headaches have been documented across the ages. “The earliest account of headache comes by way of the Mesopotamians in 4000BC,” write experts in a book on the topic. They linked the disease to an evil spirit who attacked his victims' heads.

Ancient healing texts propose bizarre remedies for what modern experts would classify as a headache disorder. In the middle ages, severe headache was identified as a distinct condition, with therapies including bloodletting to other, more folk cures.

It was a European doctor who provided the first comprehensive description of a cluster-type attack. In his medical observations, he speaks of a patient “afflicted with a very intense headache occurring and disappearing daily at specific hours”.

Cluster headaches were only formally classified by global headache societies in 1988. From the 1960s to the 1990s, they were believed to be caused by a issue with a major artery that supplies blood to the head. Leading specialists in treating the condition note this.

In 1998, researchers published the findings of a study for which they had induced attacks in patients and monitored the attacks in a brain scanner. The data, published in a major medical publication, showed activation of the a brain region, which is in charge for human sleep-wake cycles, when patients were in pain, and a reduction when they felt better.

In spite of such progress, identification remains slow. Jamie Charteris's symptoms started in 1986 and felt like “a modelling balloon being inflated behind my left eye”. GPs thought he had a sinus issue; he had multiple surgeries before eventually being diagnosed in recently, after a physician researched his symptoms.

Specialists say wait times in diagnosing and managing occur because patients are rarely seen mid-attack. “You're exhausted and low, but not in severe pain,” one says. He proceeds by eliminating other primary headache conditions, such as tension-type headache, before diagnosing the disorder. A detailed history is crucial: on which side do symptoms occur? For how long? What time of year? Are there precipitating factors, such as alcohol? Specific characteristics such as redness, drooping eyelids and stuffy nose help confirm the diagnosis. Once diagnosed, patients may be sent to specialist centers. But a lot of first arrive to A&E or are given unsuitable treatments.

Dorothy Chapman, 78, has experienced cluster headaches for most of her adult life, although she has been free from an attack since recent years. When she was in her 20s, she had her teeth pulled because dental professionals misinterpreted her pain. She thinks dentists still need greater awareness. When another patient sought help from a support group, it was Chapman who replied. The author recalls calling a helpline during an bout in early 2021; a calm advisor guided them through oxygen therapy and drugs until the attack eased.

Official guidelines on treatment advise that patients are offered high-flow oxygen therapy and/or a anti-migraine medication delivered by injection. No oral painkillers or strong analgesics should be used. Preventive choices include a blood pressure medication, which reportedly soothes the bouts of some people.

But leading specialists believe the official guidelines need revising to reflect a more defined treatment pathway and help GPs avoid incorrect prescriptions. For episodic patients, the treatment window is critical: “The duration of the cycle dictates the approach.” Brief cycles with occasional attacks are handled with abortive treatment alone. More prolonged or more severe periods require preventative medications such as verapamil, sometimes combined with corticosteroids. A significant number of patients also receive a greater occipital nerve block during a bout – an procedure into the area of the skull where the discomfort is that reduces nerve activity.

The national guidance need revising to reflect a
