Excruciating Suffering: A Personal Struggle With the Enigmatic Pain of Cluster Headache Syndrome

It began on a overcast Monday morning in the autumn of 2016. I worked as a teacher, attempting to manage a new class, when a intense pain bloomed behind my right eye. It was followed by quick jolts, similar to lightning bolts. As the school day progressed, the pain subsided and then came back with greater 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 paracetamol, but the agony remained unbearable.

The attacks appeared repeatedly that fall, and again in spring, soon forming an yearly pattern. September and October were the most severe, then February and March. I could anticipate the routine: a warning sensation in the shower, early pangs on the train, full-blown pain in class by mid-morning. In 2019, a GP eventually sent me to a specialist and I was given a diagnosis with cluster headache disorder.

This condition typically start with severe pain behind one eye that persists for several hours.

About 1 in 1000 people suffer by the condition, and males are more frequently diagnosed. Attacks usually begin with sudden, severe pain around a single eye that peaks within a short time and continues for up to three hours. Attacks come in clusters, every day or multiple times a day, and are associated with tearing eyes, sagging eyelids or face sweating. I have an episodic type, which arrives in seasonal bouts; some patients have chronic cluster headaches, characterized by the lack of extended symptom-free periods.

What connects patients is the severity. One study scored the pain at 9.7 10, higher than bone fractures or pancreatitis. Another discovered 64% of cluster headache patients reported thoughts of self-harm during attacks; the number dropped to four percent when they were not in pain.

Val Hobbs, 74, a long-term patient from Pembrokeshire, isn't surprised. Her episodes started 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 symptoms deteriorated through childhood. Drinking in her adolescence, like many triggers, made things worse. After having alcohol at her school leaving party, she recalls hardly being able to see on the transport home.

Her relatives often mistook her episodes as intoxicated episodes. Understanding eventually came from her parent and then from her partner, her spouse. “I was very fortunate to find such an understanding person,” she says. Hobbs found clerical work after relocating, but often hid her illness. She was fired from one job, in part due to time off during episodes. Her definitive diagnosis came in the early 2000s at a national hospital.

Still, the failure to plan daily activities around erratic pain took its effect. She particularly hated 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 paralysis caused by the most severe episodes. “It robs you of the simple liberties 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 history. “The first description of headache originates from the Mesopotamians in antiquity,” write authors in a publication on the subject. They attributed the disease to an malevolent spirit who afflicted his sufferers' heads.

Ancient medical records suggest bizarre treatments for what modern experts would describe as a migraine. In the medieval times, migraine was recognised as a distinct disorder, with treatments including herbal concoctions to other, more folk remedies.

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

The disorder were only formally recognised by global medical societies in 1988. From the mid-20th century to the late 1990s, they were thought to be caused by a issue with a major blood vessel which delivers blood to the brain. Leading experts in diagnosing the disorder note this.

In 1998, researchers published the findings of a study for which they had induced cluster headaches in patients and monitored the episodes in a imaging machine. The results, featured in a major journal, showed increased activity of the a brain region, which is responsible for human circadian rhythm, when patients were in discomfort, and a deactivation when they felt better.

Despite such advances, diagnosis remains slow. One man's symptoms started in the 1980s and felt like “a balloon being blown up behind my left eye”. GPs thought he had sinus problems; he had four surgeries before eventually being correctly identified in recently, after a doctor looked up his complaints.

Neurologists say delays in diagnosis and managing happen because patients are rarely seen during an episode. “You're tired and low, but not in severe pain,” one says. He works by ruling out other primary head pain disorders, such as tension-type headache, before confirming the disorder. A thorough history is essential: on which part of the head do symptoms appear? For how long? What time of year? Are there precipitating factors, such as alcohol? Certain features such as redness, drooping eyelids and stuffy nose help verify the diagnosis. Once identified, patients may be referred to specialist clinics. But many first go to A&E or are given unsuitable treatments.

Dorothy Chapman, 78, has suffered from the condition for the majority of her life, although she hasn't had an episode since 2016. When she was in her 20s, she had her molars extracted because dental professionals misunderstood her symptoms. She thinks dentists still need much more awareness. When another patient sought help from a charity, it was Chapman who responded. I remember calling a helpline during an bout in 2021; a calm advisor guided me through oxygen therapy and medication until the attack eased.

Official guidance on treatment advise that patients are offered high-flow oxygen and/or a anti-migraine medication administered by injection. No oral painkillers or strong analgesics should be used. Preventive options include verapamil, which reportedly helps manage the attacks of some individuals.

But leading specialists argue the guidance need updating to reflect a more defined clinical process and help general practitioners avoid incorrect prescriptions. For periodic patients, timing is everything: “The duration of the bout dictates the treatment.” Brief cycles with occasional attacks are handled with abortive therapy only. More prolonged or more intense periods require preventative medications such as certain drugs, sometimes paired with steroids. A significant number of patients also receive a nerve block injection during a bout – an procedure into the side of the head where the discomfort is that reduces nerve signals.

The official guidelines need revising to reflect a
