Unbearable Agony: My Struggle Against the Enigmatic Suffering of Cluster Headache Syndrome
It began on a overcast Monday in the morning in September 2016. I was working as a educator, trying to settle a new class, when a sharp pain sprang behind my right eye. Then came rapid shocks, similar to electric shocks. As the school day came and went, the pain eased and then came back with increased intensity. Multiple times that day I handed over a teaching assistant with activities and hurried to the school bathroom to soak my face with cold water. I took aspirin, but the pain remained unrelenting.
The headaches returned repeatedly that autumn, and once more in spring, soon forming an annual cycle. September and October were the most severe, then February and March. I could anticipate the pattern: a warning sensation in the shower, early twinges on the train, full-on agony in the classroom by 9.30am. In late 2019, a doctor eventually sent me to a specialist and I was diagnosed with cluster headaches.
This condition often start with intense pain around a single eye that lasts for several hours.
Approximately 1 in 1000 individuals are affected by the disorder, and males are more frequently diagnosed. Attacks usually start with abrupt, severe pain around one eye that peaks within minutes and continues for as long as three hours. Episodes come in clusters, daily or multiple times a day, and are associated with tearing eyes, drooping eyelids or facial sweating. I have the episodic form, which occurs in seasonal bouts; some patients have chronic cluster headaches, characterized by the lack of long symptom-free periods.
What unites sufferers is the severity. One research paper scored the pain at 9.7 10, more severe than bone fractures or pancreatitis. A separate discovered 64% of cluster headache patients experienced thoughts of self-harm amid bouts; the number fell to four percent when they were pain-free.
Val Hobbs, in her seventies, a long-term patient from Pembrokeshire, isn't surprised. Her attacks began when she was a toddler. “I would throw myself on the ground and hit my head. That was put down to being a difficult child,” she says. Her symptoms deteriorated through her youth. Drinking in her adolescence, similar to many causes, made things more intense. After having alcohol at her graduation party, she recalls hardly being able to see on the transport home.
Her family often mistook her episodes as intoxicated episodes. 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 illness. She was dismissed from one job, partly due to time off during episodes. Her definitive identification came in 2002 at a specialist neurology center.
Still, the inability to organize life around erratic pain took its toll. She especially disliked being unable to plan social events, being seen as flaky as a co-worker, and even having to be looked after by her children during the paralysis caused by the most severe episodes. “It steals from you of the small freedoms we don't value until they're gone,” she says. She recalls obtaining tickets for a major concert, only to have an attack inside a facility.
Headaches have been documented throughout the ages. “The first account of headache originates from the Mesopotamians in antiquity,” write authors in a publication on the subject. They attributed the ailment to an evil spirit who afflicted his sufferers' heads.
Ancient medical texts suggest unusual remedies for what some experts would classify as a headache disorder. In the medieval times, severe headache was recognised as a distinct disorder, with therapies ranging from bloodletting to other, more superstitious remedies.
It was a European doctor who provided the initial detailed description of a cluster headache. In his medical observations, he speaks of a patient “afflicted with a very severe headache occurring and disappearing daily at specific hours”.
Cluster headaches were only formally classified by international headache societies in the late 1980s. From the mid-20th century to the late 1990s, they were believed to be caused by a issue with a major artery which delivers blood to the brain. Prominent experts in diagnosing the disorder note this.
In the late 1990s, scientists published the results of a study for which they had triggered cluster headaches in patients and monitored the attacks in a brain scanner. The data, published in a major journal, showed activation of the a brain region, which is in charge for human circadian rhythm, when patients were in pain, and a deactivation when they recovered.
In spite of such progress, identification remains delayed. One man's attacks 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 operations before finally being diagnosed in recently, after a physician looked up his symptoms.
Neurologists say wait times in diagnosing and treatment happen because patients are rarely seen during an episode. “You're exhausted and low, but not in agony,” one says. He proceeds by ruling out other primary head pain disorders, such as tension-type headache, before diagnosing cluster headaches. A thorough history is crucial: on which side do symptoms occur? For how long? What time of year? Are there precipitating factors, such as alcohol? Specific features such as tearing, sagging eyelids and nasal congestion help confirm the diagnosis. Once diagnosed, patients may be referred to dedicated centers. But many first go to emergency rooms or are given unsuitable treatments.
A charity trustee, in her late seventies, has experienced the condition for the majority of her life, although she has been free from an episode since 2016. When she was in her 20s, she had her teeth extracted because dental professionals misinterpreted her symptoms. She believes the dental profession still need much more education. When another patient sought help from a charity, it was she who replied. The author recalls calling a helpline during an attack in early 2021; a reassuring advisor talked them through oxygen treatment and medication until the episode eased.
Official guidelines on management recommend that patients are offered high-dose oxygen therapy and/or a anti-migraine medication administered by injection. No oral painkillers or opioids should be used. Preventive options include a blood pressure medication, which apparently soothes the bouts of well-known people.
But consultant specialists believe the official guidelines need revising to reflect a clearer treatment process and help general practitioners avoid incorrect prescriptions. For episodic patients, the treatment window is critical: “The length of the bout determines the approach.” Short cycles with infrequent episodes are managed with acute treatment alone. More prolonged 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 injection into the side of the head where the discomfort is that reduces nerve activity.
The official guidelines need updating to reflect a
