Excruciating Agony: A Personal Struggle Against the Puzzling Suffering of Cluster Headache Syndrome

It was a overcast weekday in the morning in September 2016. I was working as a teacher, trying to settle a new group of students, when a sudden pain sprang behind my one eye. It was followed by rapid jolts, like electric shocks. As each class progressed, the discomfort eased and then returned with greater intensity. Four times that day I left a colleague with worksheets and hurried to the school bathroom to soak my face with cold water. I tried paracetamol, but the agony remained unbearable.

The attacks appeared repeatedly that fall, and once more in spring, soon forming an annual cycle. September and October were the worst, then February and March. I could predict the routine: a warning sensation in the morning, early pangs on the commute, full-on pain in class by mid-morning. In 2019, a GP eventually referred me to a specialist and I was diagnosed with cluster headaches.

This condition often start with severe pain behind a single eye that persists up to three hours.

Approximately 1 in 1000 people are affected by the disorder, and males are more frequently affected. Attacks usually begin with sudden, severe agony around a single eye that reaches its peak within minutes and lasts for up to three hours. Episodes come in clusters, daily or multiple times a day, and are associated with tearing eyes, drooping eyelids or face sweating. There exists the episodic form, which arrives in seasonal bouts; some patients have chronic attacks, characterized by the absence of long symptom-free periods.

What unites sufferers is the severity. One study rated the pain at 9.7 10, more severe than broken bones or other conditions. A separate discovered a significant percentage of cluster headache patients experienced suicidal thoughts during bouts; the number dropped to 4% when they were not in pain.

Val Hobbs, in her seventies, a chronic sufferer from Pembrokeshire, isn't surprised. Her attacks began when she was two. “I would throw myself on the ground and hit my head. That was attributed to being a difficult child,” she says. Her condition deteriorated through her youth. Alcohol in her adolescence, like several triggers, made things more intense. After drinking alcohol at her school leaving party, she remembers barely being able to see on the bus home.

Her family often interpreted her episodes as intoxicated episodes. Support finally came from her father and then from her partner, her spouse. “I was very fortunate to find such an understanding person,” she says. Hobbs found office work after relocating, but often hid her condition. She was dismissed from one job, partly due to absences during attacks. Her breakthrough identification came in the early 2000s at a national neurology center.

Still, the failure to organize daily activities around erratic attacks took its effect. She particularly hated being unable to plan outings, being seen as flaky as a co-worker, and even having to be looked after by her family during the paralysis caused by the most severe episodes. “It robs you of the small liberties we don't value until they're gone,” she says. She remembers winning tickets for a major concert, only to have an attack inside a portable toilet.

Headaches have been documented throughout history. “The first description of headache comes by way of the ancient civilizations in 4000BC,” write authors in a book on the topic. They linked the ailment to an evil spirit who attacked his victims' heads.

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

It was a Dutch physician who provided the initial comprehensive account of a cluster-type attack. In his medical observations, he describes a patient “suffering with a very severe headache occurring and vanishing daily at specific hours”.

The disorder were only formally classified by global headache committees in the late 1980s. From the mid-20th century to the late 1990s, they were thought to be caused by a issue with a key artery that delivers blood to the head. Leading experts in treating the disorder note this.

In 1998, researchers published the results of a study for which they had triggered attacks in patients and observed the episodes in a imaging machine. The results, featured in a prominent medical publication, showed increased activity of the a brain region, which is in charge for human circadian rhythm, when patients were in discomfort, and a deactivation when they recovered.

Despite such advances, identification remains delayed. Jamie Charteris's symptoms started in 1986 and felt like “a balloon being inflated behind my left eye”. Doctors thought he had sinus problems; he underwent multiple operations before finally being correctly identified in 2014, after a physician researched his symptoms.

Specialists say wait times in diagnosis and managing occur because patients are rarely seen mid-attack. “You're tired and low, but not in severe pain,” one says. He proceeds by eliminating other common head pain disorders, such as tension-type headache, before diagnosing the disorder. A thorough patient history is essential: on which part of the head do symptoms occur? For how long? What season? Are there precipitating factors, such as certain foods? Certain characteristics such as tearing, sagging eyelids and nasal congestion help confirm cluster headaches. Once identified, patients may be sent to dedicated centers. But many first go to emergency rooms or are given inadequate treatments.

Dorothy Chapman, 78, has suffered from the condition 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 molars extracted because dental professionals misunderstood her pain. She thinks dentists still need greater awareness. When a sufferer sought help from a support group, it was she who replied. I remember calling a helpline during an attack in early 2021; a reassuring volunteer guided me through oxygen treatment and medication until the attack eased.

Official guidance on treatment recommend that patients are offered high-flow oxygen therapy and/or a specific medication delivered by nasal spray. No oral painkillers or strong analgesics should be used. Prophylactic choices include a blood pressure medication, which apparently helps manage the bouts of well-known people.

But consultant specialists argue the guidance need updating to reflect a clearer treatment pathway and help general practitioners avoid incorrect prescriptions. For periodic patients, timing is everything: “The duration of the cycle determines the treatment.” Short bouts with infrequent attacks are managed with acute treatment alone. Longer or more severe bouts require preventative medications such as certain drugs, sometimes paired with steroids. Many patients also receive a greater occipital nerve block during a cycle – an procedure into the side of the head where the discomfort is that reduces nerve signals.

The official guidelines need revising to reflect a
