Unbearable Pain: A Personal Struggle Against the Enigmatic Pain of Cluster Headache Syndrome

It was a dreary weekday in the morning in September 2016. I was working as a teacher, trying to settle a new class, when a intense sensation erupted behind my right eye. It was followed by quick jolts, reminiscent of lightning bolts. As the school day came and went, the discomfort subsided and then came back with greater force. Multiple times that day I handed over a teaching assistant with activities and ran to the staff bathroom to soak my face with cool water. I took ibuprofen, but the pain remained unrelenting.

The attacks appeared frequently that fall, and once more in the spring, soon establishing an yearly cycle. September and October were the most severe, then February and March. I could anticipate the pattern: a warning sensation in the morning, early twinges on the train, full-on pain in the classroom by mid-morning. In late 2019, a doctor finally sent me to a specialist and I was given a diagnosis with cluster headache disorder.

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

About 1 in 1000 people suffer by the condition, and males are more often affected. Cluster headaches usually start with abrupt, excruciating agony around one eye that reaches its peak within a short time and lasts for up to three hours. Episodes occur in cycles, every day or several times a day, and are accompanied by red or watery eyes, drooping eyelids or facial perspiration. There exists an episodic type, which arrives in periodic bouts; some patients have chronic attacks, defined by the absence of long pain-free periods.

What unites sufferers is the severity. One research paper scored the sensation at 9.7 10, higher than bone fractures or other conditions. A separate found a significant percentage of cluster patients reported suicidal thoughts amid bouts; the figure fell to four percent when they were pain-free.

One patient, in her seventies, a chronic patient from Wales, finds this understandable. Her attacks started when she was a toddler. “I would hurl myself on the ground and hit my head. That was attributed to being spoiled,” she says. Her condition deteriorated through childhood. Drinking in her adolescence, like many causes, made things worse. After having sherry at her graduation party, she recalls hardly being able to see on the bus home.

Her relatives often mistook her attacks as drunken episodes. Support eventually came from her parent and then from her partner, Rod. “I was very fortunate to find such an understanding person,” she says. Hobbs found office work after relocating, but often concealed her condition. She was dismissed from one job, in part due to absences during attacks. Her definitive diagnosis came in 2002 at a national hospital.

Still, the inability to plan daily activities around erratic attacks took its effect. She especially hated being unable to plan social events, being seen as flaky as a colleague, and even having to be cared for by her children during the incapacitation caused by the worst episodes. “It robs you of the simple freedoms we don't value until they're gone,” she says. She remembers obtaining tickets for a significant concert, only to have an episode inside a portable toilet.

Headaches have been described across history. “The first account of headache comes by way of the Mesopotamians in 4000BC,” write experts in a book on the topic. They attributed the ailment to an evil spirit who attacked his victims' heads.

Historical medical records propose bizarre treatments for what some observers would describe as a headache disorder. In the medieval times, migraine was recognised as a separate condition, with treatments including bloodletting to other, more folk remedies.

It was a Dutch doctor who provided the first detailed account of a cluster headache. In his writings, he describes a patient “afflicted with a very severe headache happening and disappearing daily at specific hours”.

The disorder were only officially classified by global medical committees in 1988. From the mid-20th century to the late 1990s, they were thought to be caused by a problem with a major blood vessel which delivers blood to the brain. Prominent specialists in treating the condition explain this.

In 1998, scientists released the findings of a study for which they had induced cluster headaches in patients and monitored the episodes in a imaging machine. The results, published in a major medical publication, showed activation of the hypothalamus, which is in charge for human circadian rhythm, when patients were in pain, and a reduction when they felt better.

Despite such progress, identification remains slow. Jamie Charteris's symptoms started in the 1980s and felt like “a modelling balloon being inflated behind my left eye”. GPs thought he had sinus problems; he had four operations before eventually being diagnosed in recently, after a doctor researched his symptoms.

Neurologists say wait times in diagnosis and managing happen because patients are rarely seen mid-attack. “You're exhausted and depressed, but not in severe pain,” one says. He works by ruling out other primary headache conditions, such as migraine, before confirming the disorder. A thorough history is crucial: on which part of the head do symptoms occur? For how much time? What season? Are there triggers, such as certain foods? Specific characteristics such as tearing, drooping eyelids and stuffy nose help confirm the diagnosis. Once identified, patients may be sent to dedicated centers. But many first arrive to emergency rooms or are given inadequate treatments.

A charity trustee, in her late seventies, has experienced cluster headaches for the majority of her adult life, although she hasn't had an episode since recent years. When she was in her 20s, she had her molars extracted because dentists misunderstood her symptoms. She believes dentists still need much more awareness. When another patient sought help from a charity, it was Chapman who responded. I remember calling a support line during an attack in 2021; a calm advisor talked me through oxygen treatment and drugs until the attack passed.

National guidance on treatment recommend that patients are offered high-dose oxygen and/or a specific medication delivered by nasal spray. No oral painkillers or opioids should be used. Prophylactic options include a blood pressure medication, which apparently soothes the attacks of well-known individuals.

But consultant specialists believe the official guidelines need revising to reflect a more defined clinical process and help GPs avoid misprescribing. For episodic patients, timing is critical: “The duration of the bout dictates the approach.” Short cycles with occasional episodes are managed with abortive treatment alone. More prolonged or more intense bouts require preventives such as verapamil, sometimes combined with corticosteroids. Many patients also receive a greater occipital nerve block during a cycle – an injection into the side of the skull where the discomfort is that decreases nerve signals.
