Excruciating Pain: A Personal Fight With the Mysterious Pain of Cluster Headache Syndrome

It was a gloomy Monday morning in September 2016. I worked as a teacher, attempting to manage a new class, when a sharp sensation bloomed behind my one eye. It was followed by quick stabs, reminiscent of lightning bolts. As the school day came and went, the discomfort eased and then returned with greater intensity. Multiple times that day I handed over a teaching assistant with worksheets and hurried to the school bathroom to douse my face with cool water. I took aspirin, but the agony remained unbearable.

The attacks appeared repeatedly that fall, and once more 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 twinges on the commute, full-on pain in class by 9.30am. In late 2019, a doctor eventually referred me to a specialist and I was diagnosed with cluster headache disorder.

This condition typically start with intense discomfort around one eye that persists for three hours.

Approximately one in 1,000 individuals suffer by the disorder, and males are more frequently affected. Attacks typically begin with sudden, excruciating agony around one eye that peaks within minutes and lasts for as long as three hours. Episodes occur in cycles, every day or multiple times a day, and are associated with red or watery eyes, sagging eyelids or face sweating. I have an episodic type, which occurs in periodic bouts; some patients have chronic attacks, characterized by the absence of extended symptom-free periods.

What connects patients is the severity. One research paper scored the sensation at 9.7 10, more severe than broken bones or pancreatitis. Another found 64% of cluster patients experienced suicidal thoughts amid attacks; the figure dropped to four percent when they were pain-free.

One patient, 74, a chronic patient from Pembrokeshire, isn't surprised. Her attacks began 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 her youth. Alcohol in her adolescence, like many causes, made things more intense. After having sherry at her school leaving party, she recalls barely being able to see on the bus home.

Her relatives often interpreted her attacks as drunken behavior. Understanding eventually came from her father and then from her husband, Rod. “I was very fortunate to find such an understanding person,” she says. Hobbs found clerical work after relocating, but often concealed her condition. She was fired from one job, in part due to time off during episodes. Her definitive diagnosis came in 2002 at a national hospital.

Nevertheless, the inability to organize daily activities around unpredictable attacks took its effect. She especially disliked being unable to plan outings, being seen as unreliable as a colleague, and even having to be cared for by her children 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 remembers winning tickets for a major concert, only to have an attack inside a facility.

Headaches have been documented throughout history. “The earliest description of headache comes by way of the Mesopotamians in antiquity,” write experts in a book on the topic. They attributed the ailment to an evil entity who attacked his sufferers' heads.

Historical healing records propose unusual remedies for what some experts would describe as a migraine. In the middle ages, severe headache was identified as a distinct condition, with treatments ranging from herbal concoctions to other, more folk remedies.

It was a Dutch physician who provided the first comprehensive description of a cluster-type attack. In his writings, he speaks of a patient “suffering with a very severe headache occurring and disappearing each day at fixed hours”.

Cluster headaches were only officially classified by international medical committees in 1988. From the mid-20th century to the 1990s, they were believed to be caused by a issue with a major blood vessel which delivers blood to the head. Prominent specialists in diagnosing the disorder note this.

In 1998, researchers published the findings of a study for which they had induced attacks in patients and monitored the episodes in a imaging machine. The results, featured in a prominent journal, showed activation of the hypothalamus, which is responsible for human sleep-wake cycles, when patients were in discomfort, and a deactivation when they felt better.

In spite of such advances, diagnosis remains slow. Jamie Charteris's symptoms began in 1986 and felt like “a balloon being blown up behind my left eye”. Doctors thought he had a sinus issue; he underwent four surgeries before finally being diagnosed in recently, after a doctor looked up his symptoms.

Neurologists say wait times in diagnosing and treatment occur because patients are rarely seen during an episode. “You're exhausted and depressed, but not in severe pain,” a doctor says. He works by ruling out other common headache disorders, such as tension-type headache, before confirming cluster headaches. A detailed patient history is essential: on which part of the head do symptoms occur? For how much time? What season? Are there precipitating factors, such as certain foods? Certain characteristics such as redness, sagging eyelids and stuffy nose help verify the diagnosis. Once identified, patients may be sent to specialist centers. But many first arrive to emergency rooms or are given unsuitable therapies.

A charity trustee, in her late seventies, has experienced cluster headaches for most of her life, although she hasn't had an episode since recent years. When she was in her twenties, she had her teeth extracted because dentists misinterpreted her symptoms. She believes the dental profession still need much more awareness. When another patient sought help from a charity, it was Chapman who replied. I remember calling a helpline during an bout in 2021; a reassuring advisor guided me through oxygen treatment and medication until the attack eased.

Official guidelines on management recommend that patients are offered high-flow oxygen therapy and/or a anti-migraine drug administered by nasal spray. No tablets or strong analgesics should be used. Preventive choices include a blood pressure medication, which reportedly soothes the bouts of some people.

But leading neurologists argue the guidance need revising to reflect a more defined treatment process and help general practitioners avoid misprescribing. For periodic patients, timing is everything: “The length of the cycle determines the treatment.” Brief cycles with occasional attacks are managed with acute treatment only. Longer or more intense bouts require preventative medications such as certain drugs, sometimes paired with corticosteroids. Many patients also receive a greater occipital nerve block during a bout – an procedure into the area of the skull where the pain is that reduces nerve signals.

The national guidelines need revising to reflect a
