Excruciating Suffering: A Personal Fight Against the Enigmatic Pain of Cluster Headaches
It began on a overcast weekday morning in the autumn of 2016. I worked as a teacher, attempting to manage a new class, when a intense pain erupted behind my right eye. This was followed by quick shocks, similar to electric shocks. As the school day progressed, the discomfort eased and then returned with greater force. Multiple times that day I handed over a teaching assistant with worksheets and hurried to the staff bathroom to soak my face with cold water. I tried aspirin, but the agony remained unrelenting.
The headaches returned frequently that fall, and once more in the spring, soon forming an yearly cycle. The autumn months were the worst, then the late winter. I could predict the routine: aura in the shower, early pangs on the commute, 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 headaches.
This condition typically start with severe pain behind a single eye that lasts up to three hours.
Approximately 1 in 1000 individuals suffer by the condition, and males are more often diagnosed. Cluster headaches typically start with sudden, excruciating agony focused on a single eye that reaches its peak within minutes and continues for as long as three hours. Attacks come in clusters, daily or multiple times a day, and are accompanied by red or watery eyes, drooping eyelids or facial perspiration. There exists an episodic type, which occurs in periodic cycles; others have chronic cluster headaches, defined by the lack of long pain-free periods.
What unites sufferers is the severity. One study scored the pain at 9.7 10, higher than bone fractures or pancreatitis. Another discovered 64% of cluster patients reported suicidal thoughts during bouts; the figure dropped to four percent when they were not in pain.
One patient, in her seventies, a long-term sufferer from Pembrokeshire, isn't surprised. Her episodes started when she was two. “I would hurl myself on the ground and hit my head. That was put down to being a difficult child,” she says. Her condition worsened through her youth. Drinking in her adolescence, similar to several causes, made things more intense. After drinking alcohol at her graduation party, she remembers barely being able to see on the transport home.
Her family often interpreted her attacks as drunken episodes. Support eventually came from her father and then from her husband, Rod. “I was very lucky to find such an exceptional person,” she says. Hobbs found clerical work after moving, but often hid her illness. She was dismissed from one job, in part due to absences during attacks. Her definitive identification came in 2002 at a specialist neurology center.
Still, the inability to organize life around erratic pain took its toll. She particularly hated being unable to plan social events, being seen as flaky as a co-worker, and even having to be cared for by her children during the incapacitation caused by the worst episodes. “It steals from you of the simple freedoms we don't appreciate until they're gone,” she says. She remembers obtaining tickets for a significant concert, only to have an episode inside a portable toilet.
Headaches have been described across the ages. “The first description of headache originates from the ancient civilizations in 4000BC,” write experts in a publication on the subject. They attributed the ailment to an malevolent entity who afflicted his victims' heads.
Ancient medical records propose bizarre treatments for what some observers would describe as a migraine. In the middle ages, severe headache was identified as a distinct condition, with treatments including bloodletting to other, more superstitious cures.
It was a Dutch physician who provided the initial detailed account of a cluster headache. In his writings, he speaks of a patient “suffering with a very severe headache occurring and vanishing daily at specific hours”.
Cluster headaches were only formally classified by global medical societies 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 brain. Prominent specialists in diagnosing the disorder explain this.
In the late 1990s, scientists published the findings of a research project for which they had induced attacks in patients and monitored the episodes in a brain scanner. The data, published in a prominent journal, showed increased activity of the a brain region, which is in charge for human circadian rhythm, when patients were in discomfort, and a reduction when they felt better.
Despite such progress, diagnosis remains delayed. One man's attacks started in 1986 and felt like “a balloon being inflated behind my one eye”. Doctors thought he had sinus problems; he had multiple surgeries before eventually being correctly identified in 2014, after a physician looked up his complaints.
Neurologists say wait times in diagnosis and treatment happen because patients are seldom seen mid-attack. “You're exhausted and depressed, but not in agony,” one says. He works by ruling out other primary headache conditions, such as tension-type headache, before diagnosing the disorder. A detailed history is essential: on which part of the head do symptoms occur? For how long? What time of year? Are there precipitating factors, such as alcohol? Specific features such as redness, drooping eyelids and stuffy nose help verify cluster headaches. Once diagnosed, patients may be sent to dedicated centers. But a lot of first arrive to emergency rooms or are given inadequate therapies.
Dorothy Chapman, 78, has suffered from cluster headaches for most of her life, although she has been free from an attack since 2016. When she was in her twenties, she had her teeth extracted because dentists misinterpreted her symptoms. She thinks dentists still need greater awareness. When a sufferer sought help from a support group, it was Chapman who responded. I remember calling a helpline during an bout in 2021; a reassuring volunteer guided me through oxygen treatment and drugs until the attack passed.
National guidance on treatment recommend that patients are offered high-dose oxygen therapy and/or a specific drug administered by nasal spray. No tablets or opioids should be used. Prophylactic options include a blood pressure medication, which reportedly soothes the bouts of some people.
But leading neurologists argue the official guidelines need updating to reflect a clearer treatment pathway and help GPs avoid misprescribing. For episodic patients, timing is critical: “The length of the bout dictates the approach.” Brief cycles with infrequent attacks are managed with abortive treatment only. More prolonged or more intense periods require preventives such as certain drugs, sometimes combined with steroids. Many patients also receive a nerve block injection during a cycle – an procedure into the side of the skull where the pain is that decreases nerve activity.
The national guidance need revising to reflect a
