Unbearable Agony: A Personal Struggle With the Enigmatic Suffering of Cluster Headaches

It began on a dreary weekday in the morning in September 2016. I worked as a teacher, attempting to manage a new class, when a intense pain sprang behind my one eye. Then came quick jolts, similar to electric shocks. As the school day came and went, the discomfort eased and then came back with increased intensity. Four times that day I left a teaching assistant with activities and hurried to the staff bathroom to douse my face with cool water. I tried ibuprofen, but the pain remained unbearable.

The headaches appeared frequently that fall, and once more in spring, soon establishing an yearly pattern. September and October were the worst, then February and March. I could predict the pattern: a warning sensation in the shower, early twinges on the commute, full-blown agony in class by mid-morning. In late 2019, a doctor eventually referred me to a specialist and I was diagnosed with cluster headaches.

Cluster headaches typically start with severe discomfort around one eye that lasts for several hours.

Approximately 1 in 1000 people are affected by the condition, and males are more often diagnosed. Cluster headaches typically start with abrupt, severe pain focused on a single eye that reaches its peak within minutes and continues for as long as three hours. Attacks come in clusters, daily or multiple times a day, and are accompanied by red or watery eyes, sagging eyelids or facial perspiration. There exists an episodic type, which arrives in seasonal bouts; some patients have continuous attacks, defined by the absence of extended symptom-free periods.

What unites sufferers is the severity. One research paper scored the pain at 9.7 out of 10, more severe than broken bones or pancreatitis. Another discovered a significant percentage of cluster patients experienced suicidal thoughts during bouts; the figure dropped to four percent when they were not in pain.

One patient, in her seventies, a chronic sufferer from Pembrokeshire, isn't surprised. Her episodes began when she was two. “I would hurl myself on the floor and hit my head. That was attributed to being spoiled,” she says. Her symptoms deteriorated through childhood. Drinking in her teens, similar to several causes, made things more intense. After drinking alcohol at her graduation party, she remembers barely being able to see on the bus home.

Her family often mistook her episodes as intoxicated episodes. Understanding eventually came from her father and then from her husband, her spouse. “I was very fortunate to find such an understanding person,” she says. Hobbs took clerical work after moving, but often concealed her illness. She was dismissed from one job, partly due to absences during attacks. Her definitive identification came in the early 2000s at a specialist neurology center.

Nevertheless, the inability to plan daily activities around erratic attacks took its toll. She especially disliked 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 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 remembers obtaining tickets for a significant concert, only to have an episode inside a facility.

Headaches have been documented throughout the ages. “The first description of headache originates from the Mesopotamians in antiquity,” write authors in a publication on the topic. They linked the disease to an malevolent entity who afflicted his victims' heads.

Historical medical records suggest bizarre remedies for what modern experts would classify as a migraine. In the middle ages, severe headache was recognised as a separate disorder, with therapies including bloodletting to other, more superstitious remedies.

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

The disorder were only formally recognised by global medical committees in 1988. From the mid-20th century to the late 1990s, they were thought to be caused by a issue with a key blood vessel that supplies blood to the brain. Prominent experts in diagnosing the condition note this.

In 1998, researchers published the results of a study for which they had triggered attacks in patients and monitored the episodes in a brain scanner. The data, featured in a major medical publication, showed increased activity of the a brain region, which is in charge for human circadian rhythm, when patients were in pain, and a deactivation when they recovered.

Despite such advances, identification remains delayed. One man's attacks began in 1986 and felt like “a modelling balloon being blown up behind my left eye”. GPs thought he had a sinus issue; he underwent four operations before finally being correctly identified in recently, after a doctor looked up his symptoms.

Specialists say wait times in diagnosing and managing happen because patients are seldom seen during an episode. “You're exhausted and depressed, but not in severe pain,” a doctor says. He proceeds by ruling out other primary head pain conditions, such as migraine, before confirming cluster headaches. A thorough history is crucial: on which side do signs appear? For how much time? What season? Are there precipitating factors, such as certain foods? Specific characteristics such as redness, drooping eyelids and nasal congestion help verify cluster headaches. Once diagnosed, patients may be referred to dedicated clinics. But many first go to emergency rooms or are given unsuitable treatments.

Dorothy Chapman, 78, has experienced cluster headaches for most of her life, although she hasn't had an episode since 2016. When she was in her 20s, she had her teeth pulled because dental professionals misinterpreted her symptoms. She believes dentists still need much more education. When a sufferer sought help from a support group, it was she who replied. I remember calling a helpline during an bout in 2021; a reassuring volunteer talked me through oxygen therapy and medication until the episode eased.

Official guidance on management recommend that patients are offered high-flow oxygen therapy and/or a anti-migraine drug delivered by injection. No oral painkillers or strong analgesics should be used. Preventive choices include a blood pressure medication, which reportedly soothes the attacks of well-known individuals.

But consultant neurologists believe the official guidelines need updating to reflect a clearer treatment pathway and help GPs avoid misprescribing. For episodic patients, timing is everything: “The duration of the bout dictates the treatment.” Brief bouts with occasional attacks are handled with acute therapy only. Longer or more intense periods 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 head where the pain is that reduces nerve activity.

The official guidance need revising to reflect a
