Unbearable Suffering: A Personal Battle With the Puzzling Suffering of Cluster Headaches

It was a dreary Monday in the morning in September 2016. I was working as a educator, attempting to manage a new class, when a intense pain sprang behind my right eye. It was followed by rapid jolts, reminiscent of lightning bolts. As each class progressed, the pain subsided and then returned with increased force. Four times that day I handed over a teaching assistant with activities and ran to the school bathroom to soak my face with cold water. I took paracetamol, but the pain remained unrelenting.

The headaches appeared frequently that autumn, and again in the spring, soon establishing an yearly pattern. September and October were the most severe, then the late winter. I could anticipate the pattern: a warning sensation in the morning, early pangs on the commute, full-blown pain in the classroom by 9.30am. In late 2019, a doctor finally referred me to a neurologist and I was diagnosed with cluster headache disorder.

This condition often start with severe discomfort behind a single eye that persists for several hours.

About one in 1,000 people are affected by the disorder, and men are more often affected. Attacks usually begin with sudden, severe agony around a single eye that peaks within a short time and continues for up to three hours. Attacks occur in cycles, every day or several times a day, and are associated with red or watery eyes, drooping eyelids or facial sweating. There exists the episodic form, which occurs in seasonal cycles; others have continuous cluster headaches, characterized by the absence of extended symptom-free periods.

What connects patients is the severity. One study scored the pain at 9.7 out of 10, higher than broken bones or other conditions. A separate discovered 64% of cluster headache patients experienced suicidal thoughts amid bouts; the number dropped to four percent when they were pain-free.

One patient, in her seventies, a long-term patient from Pembrokeshire, finds this understandable. Her attacks began when she was a toddler. “I would throw myself on the floor and hit my head. That was put down to being a difficult child,” she says. Her symptoms worsened through childhood. Alcohol in her adolescence, like several triggers, made things more intense. After having sherry at her school leaving party, she remembers barely being able to see on the bus home.

Her relatives often mistook her episodes as drunken behavior. Understanding finally came from her parent and then from her husband, her spouse. “I was very lucky to find such an understanding person,” she says. Hobbs found office work after relocating, but often concealed her condition. She was fired from one job, partly due to time off during attacks. Her breakthrough diagnosis came in the early 2000s at a specialist neurology center.

Nevertheless, the failure to plan daily activities around erratic pain took its toll. She particularly disliked being unable to plan social events, 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 freedoms 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 facility.

Headaches have been described across the ages. “The first account of headache comes by way of the Mesopotamians in 4000BC,” write experts in a book on the topic. They linked the ailment to an malevolent entity who afflicted his sufferers' heads.

Historical medical records propose unusual treatments for what some observers would classify as a headache disorder. In the medieval times, migraine was recognised as a distinct disorder, with therapies including bloodletting to other, more folk remedies.

It was a European physician who provided the initial comprehensive account of a cluster headache. In his writings, he speaks of a patient “afflicted with a very intense headache occurring and vanishing each day at specific hours”.

Cluster headaches were only formally classified by global headache committees in the late 1980s. From the mid-20th century to the 1990s, they were believed to be caused by a issue with a key blood vessel which supplies blood to the brain. Leading specialists in diagnosing the condition explain this.

In the late 1990s, scientists published 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 major medical publication, showed activation of the a brain region, which is in charge for human sleep-wake cycles, when patients were in pain, and a reduction when they recovered.

In spite of such advances, identification remains delayed. Jamie Charteris's symptoms began in the 1980s and felt like “a modelling balloon being inflated behind my one eye”. Doctors thought he had sinus problems; he underwent four surgeries before finally being correctly identified in recently, after a physician looked up his complaints.

Specialists say wait times in diagnosing and managing happen because patients are seldom seen during an episode. “You're tired and low, but not in agony,” a doctor says. He works by ruling out other primary head pain disorders, such as migraine, before diagnosing cluster headaches. A detailed history is crucial: on which side do symptoms appear? For how long? What season? Are there precipitating factors, such as certain foods? Specific features such as redness, sagging eyelids and stuffy nose help verify cluster headaches. Once diagnosed, patients may be sent to specialist clinics. But a lot of first arrive to emergency rooms or are given unsuitable treatments.

A charity trustee, in her late seventies, has experienced the condition for most of her life, although she hasn't had an attack since 2016. When she was in her 20s, she had her molars extracted because dental professionals misunderstood her symptoms. She believes dentists still need much more awareness. When another patient sought help from a support group, it was she who responded. I remember calling a support line during an bout in early 2021; a calm advisor guided them through oxygen therapy and medication until the episode passed.

Official guidance on treatment recommend that sufferers are offered high-dose oxygen therapy and/or a anti-migraine drug delivered by nasal spray. No tablets or strong analgesics should be used. Prophylactic options include a blood pressure medication, which reportedly helps manage the bouts of some people.

But leading neurologists believe the guidance need updating to reflect a more defined treatment process and help GPs avoid incorrect prescriptions. For periodic patients, timing is everything: “The duration of the bout dictates the approach.” Short cycles with occasional attacks are managed with acute treatment alone. More prolonged or more intense bouts require preventative medications such as verapamil, sometimes combined with corticosteroids. Many patients also receive a nerve block injection during a cycle – an injection into the area of the head where the pain is that decreases nerve activity.

The national guidance need updating to reflect a
