Unbearable Suffering: My Struggle Against the Enigmatic Suffering of Cluster Headaches

It began on a gloomy weekday in the morning in the autumn of 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 quick shocks, similar to lightning bolts. As each class progressed, the discomfort subsided and then came back with increased intensity. Multiple times that day I left a colleague with activities and ran to the school bathroom to soak my face with cool water. I took paracetamol, but the pain remained unrelenting.

The attacks returned frequently that fall, and again in spring, soon establishing an annual pattern. The autumn months were the worst, then the late winter. I could anticipate the pattern: aura in the morning, early twinges on the train, full-blown pain in class by 9.30am. In 2019, a GP finally sent me to a neurologist and I was given a diagnosis with cluster headache disorder.

Cluster headaches typically start with severe discomfort behind a single eye that persists for three hours.

About one in 1,000 individuals are affected by the condition, and men are more frequently 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 occur in cycles, daily or several times a day, and are associated with tearing eyes, sagging eyelids or face sweating. There exists an episodic type, which occurs in periodic cycles; others have chronic attacks, characterized by the lack of long pain-free periods.

What connects sufferers is the intensity. One study scored the sensation at 9.7 10, more severe than bone fractures or other conditions. Another discovered 64% of cluster patients experienced thoughts of self-harm amid bouts; the figure dropped to four percent when they were pain-free.

One patient, in her seventies, a long-term sufferer from Wales, isn't surprised. Her episodes began when she was a toddler. “I would hurl myself on the floor and hit my head. That was put down to being spoiled,” she says. Her symptoms worsened through her youth. Alcohol in her teens, similar to several triggers, made things worse. After having alcohol at her graduation party, she remembers barely being able to see on the transport home.

Her relatives often mistook her episodes as intoxicated behavior. Understanding eventually came from her father and then from her husband, her spouse. “I was very lucky to find such an exceptional person,” she says. Hobbs found clerical work after relocating, but often concealed her illness. She was fired from one job, partly due to time off during episodes. Her definitive identification came in 2002 at a national neurology center.

Nevertheless, the failure to plan daily activities around unpredictable attacks took its toll. She particularly disliked being unable to plan social events, being seen as flaky as a colleague, and even having to be looked after by her family during the paralysis caused by the worst episodes. “It robs 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 attack inside a facility.

Headaches have been described throughout the ages. “The first account of headache originates from the ancient civilizations in antiquity,” write authors in a publication on the subject. They linked the ailment to an malevolent spirit who attacked his victims' heads.

Ancient healing records suggest unusual treatments for what some observers would classify as a migraine. In the middle ages, migraine was recognised as a separate disorder, with therapies ranging from herbal concoctions to other, more superstitious remedies.

It was a European physician who provided the initial detailed account of a cluster headache. In his medical observations, he speaks of a patient “suffering with a very intense headache happening and disappearing each day at specific hours”.

Cluster headaches were only officially classified by global medical committees in 1988. From the 1960s to the late 1990s, they were thought to be caused by a problem with a key blood vessel that delivers blood to the brain. Prominent experts in treating the disorder explain this.

In 1998, scientists published the results of a research project for which they had triggered attacks in patients and monitored the attacks in a brain scanner. The results, published in a major medical publication, showed increased activity of the a brain region, which is responsible for human sleep-wake cycles, when patients were in pain, and a deactivation when they recovered.

In spite of such progress, diagnosis remains slow. One man'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 eventually being correctly identified in 2014, after a physician researched his complaints.

Specialists say delays in diagnosing and managing occur because patients are seldom seen mid-attack. “You're tired and depressed, but not in severe pain,” one says. He works by ruling out other primary headache disorders, such as migraine, before confirming the disorder. A thorough history is crucial: on which side do signs occur? For how long? What season? Are there precipitating factors, such as alcohol? Certain characteristics such as tearing, drooping eyelids and nasal congestion help verify cluster headaches. Once identified, patients may be sent to dedicated centers. But many first go to A&E or are given inadequate therapies.

A charity trustee, 78, has experienced cluster headaches for the majority of her adult life, although she has been free from an episode since recent years. When she was in her 20s, she had her teeth extracted because dentists misinterpreted her symptoms. She thinks the dental profession still need much more education. When another patient sought help from a support group, it was Chapman who responded. I remember calling a helpline during an attack in early 2021; a calm advisor talked them through oxygen treatment and drugs until the attack eased.

Official guidelines on management recommend that sufferers are offered high-flow oxygen therapy and/or a specific drug administered by injection. No tablets or strong analgesics should be used. Prophylactic options include verapamil, which reportedly soothes the bouts of some individuals.

But leading neurologists believe the official guidelines need updating to reflect a clearer treatment pathway and help GPs avoid misprescribing. For periodic patients, timing is critical: “The duration of the bout determines the approach.” Brief bouts with occasional attacks are managed with abortive therapy alone. More prolonged or more intense periods require preventives such as certain drugs, sometimes paired with steroids. Many patients also receive a nerve block injection during a bout – an procedure into the side of the head where the discomfort is that decreases nerve activity.
