Full-Blown Suffering: A Personal Fight With the Mysterious Suffering of Cluster Headaches

It began on a gloomy Monday in the morning in September 2016. I was working as a educator, attempting to manage a new group of students, when a intense sensation bloomed behind my right eye. This was followed by rapid stabs, reminiscent of electric shocks. As the school day came and went, the discomfort subsided and then came back with increased intensity. Four times that day I handed over a teaching assistant with activities and ran to the staff bathroom to douse my face with cold water. I took ibuprofen, but the pain remained unrelenting.

The headaches returned repeatedly that autumn, and once more in the spring, soon establishing an yearly pattern. September and October were the worst, then the late winter. I could predict the pattern: aura in the shower, early pangs on the train, full-on agony in class by mid-morning. In late 2019, a doctor finally sent me to a neurologist and I was diagnosed with cluster headaches.

Cluster headaches often start with severe discomfort behind a single eye that persists for several hours.

Approximately one in 1,000 people are affected by the disorder, and males are more often diagnosed. Attacks usually start with abrupt, excruciating pain focused on a single eye that peaks within a short time and continues for up to three hours. Episodes come in clusters, daily or multiple times a day, and are associated with red or watery eyes, drooping eyelids or face perspiration. There exists an episodic type, which arrives in periodic cycles; others have chronic attacks, characterized by the absence of long pain-free periods.

What unites patients is the intensity. One research paper scored the sensation at 9.7 10, more severe than broken bones or other conditions. Another found 64% of cluster patients experienced thoughts of self-harm amid attacks; the number fell to four percent when they were pain-free.

Val Hobbs, 74, a long-term patient from Wales, finds this understandable. Her attacks began when she was two. “I would throw myself on the floor and bang my head. That was attributed to being a difficult child,” she says. Her condition worsened through childhood. Drinking in her adolescence, similar to several causes, made things more intense. After having sherry at her graduation party, she recalls hardly being able to see on the transport home.

Her family often interpreted her attacks as intoxicated behavior. Support eventually came from her father and then from her partner, her spouse. “I was very lucky to find such an understanding person,” she says. Hobbs took office work after relocating, but often concealed her illness. She was fired from one job, partly due to time off during attacks. Her definitive diagnosis came in 2002 at a specialist hospital.

Nevertheless, the failure to plan life around erratic pain took its toll. She particularly disliked being unable to plan outings, being seen as flaky as a colleague, and even having to be looked after by her children during the incapacitation caused by the most severe episodes. “It steals from you of the simple freedoms we don't appreciate until they're gone,” she says. She recalls winning tickets for a major concert, only to have an episode inside a facility.

Headaches have been documented throughout history. “The first description of headache originates from the ancient civilizations in antiquity,” write authors in a book on the topic. They attributed the ailment to an malevolent entity who attacked his victims' heads.

Historical medical texts propose unusual remedies for what modern experts would classify as a migraine. In the medieval times, migraine was identified as a separate condition, with treatments including bloodletting to other, more folk cures.

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

The disorder were only formally classified by global headache committees in 1988. From the 1960s to the 1990s, they were thought to be caused by a issue with a key artery that supplies blood to the head. Prominent specialists in diagnosing the condition explain this.

In 1998, researchers released the results of a research project for which they had triggered attacks in patients and observed the attacks in a imaging machine. The data, featured in a prominent journal, showed increased activity of the hypothalamus, which is in charge for human sleep-wake cycles, when patients were in discomfort, and a reduction when they felt better.

In spite of such progress, diagnosis remains delayed. Jamie Charteris's attacks started in 1986 and felt like “a balloon being blown up behind my one eye”. GPs thought he had a sinus issue; he underwent four operations before finally being diagnosed in 2014, after a doctor looked up his symptoms.

Neurologists say delays in diagnosis and managing occur because patients are rarely seen mid-attack. “You're exhausted and depressed, but not in severe pain,” one says. He proceeds by eliminating other common head pain conditions, such as tension-type headache, before confirming cluster headaches. A thorough history is crucial: on which side do symptoms occur? For how much time? What time of year? Are there triggers, such as certain foods? Certain characteristics such as tearing, sagging eyelids and nasal congestion help confirm cluster headaches. Once identified, patients may be referred to dedicated centers. But a lot of first go to A&E or are given unsuitable therapies.

A charity trustee, 78, has suffered from the condition for most of her life, although she has been free from an episode since 2016. When she was in her 20s, she had her teeth pulled because dentists misunderstood her symptoms. She thinks the dental profession still need greater awareness. When a sufferer sought help from a charity, it was she who responded. I remember calling a helpline during an bout in 2021; a reassuring advisor talked them through oxygen treatment and medication until the attack passed.

Official guidelines on treatment advise that patients are offered high-dose oxygen and/or a specific drug delivered by injection. No oral painkillers or strong analgesics should be used. Prophylactic options include verapamil, which reportedly soothes the bouts of some individuals.

But leading specialists believe the official guidelines need revising to reflect a more defined treatment process and help GPs avoid misprescribing. For episodic patients, the treatment window is critical: “The duration of the bout determines the approach.” Short bouts with occasional episodes are handled with abortive treatment alone. More prolonged or more intense bouts require preventives such as certain drugs, sometimes paired with corticosteroids. A significant number of 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 activity.

The national guidance need revising to reflect a
