Full-Blown Pain: My Struggle Against the Puzzling Suffering of Cluster Headaches
It was a gloomy Monday in the morning in September 2016. I was working as a teacher, attempting to manage a new class, when a intense sensation sprang behind my right eye. Then came quick shocks, like electric shocks. As each class came and went, the discomfort eased and then came back with greater intensity. Multiple times that day I left a teaching assistant with activities and hurried to the school bathroom to douse my face with cool water. I took paracetamol, but the pain remained unbearable.
The headaches returned repeatedly that fall, and once more in the 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 shower, early pangs on the train, full-blown pain in class by 9.30am. In 2019, a GP eventually referred me to a neurologist and I was diagnosed with cluster headaches.
This condition typically begin with severe pain behind one eye that lasts for several hours.
Approximately 1 in 1000 people suffer by the condition, and men are more often diagnosed. Cluster headaches usually begin with abrupt, excruciating pain focused on a single eye that reaches its peak within minutes and continues for up to three hours. Episodes occur in cycles, every day or multiple times a day, and are associated with tearing eyes, sagging eyelids or face sweating. I have an episodic type, which arrives in seasonal bouts; others have continuous attacks, defined by the lack of extended symptom-free periods.
What unites patients is the severity. One study scored the sensation at 9.7 out of 10, higher than broken bones or other conditions. A separate found 64% of cluster patients experienced thoughts of self-harm amid bouts; the figure fell to 4% when they were not in pain.
Val Hobbs, in her seventies, a long-term sufferer from Pembrokeshire, isn't surprised. Her attacks started when she was two. “I would throw myself on the ground and bang my head. That was put down to being a difficult child,” she says. Her symptoms deteriorated through childhood. Alcohol in her teens, similar to several causes, made things worse. After having sherry at her school leaving party, she remembers barely being able to see on the bus home.
Her family often mistook her episodes as drunken behavior. Support eventually came from her father and then from her partner, her spouse. “I was very fortunate to find such an exceptional person,” she says. Hobbs took clerical work after relocating, but often hid her illness. She was dismissed from one job, in part due to time off during episodes. Her definitive diagnosis came in the early 2000s at a specialist neurology center.
Nevertheless, the inability to plan daily activities around unpredictable attacks took its effect. She particularly disliked 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 steals from you of the simple freedoms we don't appreciate until they're gone,” she says. She recalls obtaining tickets for a major concert, only to have an episode inside a portable toilet.
Headaches have been documented across the ages. “The earliest description of headache originates from the ancient civilizations in antiquity,” write experts in a publication on the subject. They attributed the ailment to an malevolent spirit who attacked his sufferers' heads.
Historical healing records propose unusual treatments for what modern observers would classify as a migraine. In the medieval times, severe headache was identified as a separate disorder, with therapies ranging from herbal concoctions to other, more folk cures.
It was a Dutch doctor who provided the first comprehensive account of a cluster-type attack. In his medical observations, he speaks of a patient “suffering with a very intense headache occurring and disappearing daily at specific hours”.
The disorder were only officially classified by global medical societies in 1988. From the mid-20th century to the late 1990s, they were thought to be caused by a problem with a major blood vessel that supplies blood to the brain. Leading experts in diagnosing the disorder note this.
In 1998, scientists released the results of a research project for which they had triggered cluster headaches in patients and observed the episodes in a imaging machine. The data, featured in a major medical publication, showed activation of the hypothalamus, which is in charge for human sleep-wake cycles, when patients were in pain, and a deactivation when they recovered.
In spite of such advances, diagnosis remains delayed. Jamie Charteris's symptoms began in the 1980s and felt like “a balloon being blown up behind my left eye”. Doctors thought he had sinus problems; he underwent four operations before eventually being correctly identified in 2014, after a doctor researched his complaints.
Neurologists say delays in diagnosing and managing happen because patients are seldom seen mid-attack. “You're tired and low, but not in severe pain,” one says. He works by eliminating other primary headache disorders, such as migraine, before confirming cluster headaches. A thorough patient history is crucial: on which side do signs occur? For how much time? What time of year? Are there precipitating factors, such as alcohol? Specific characteristics such as tearing, sagging eyelids and stuffy nose help confirm cluster headaches. Once diagnosed, patients may be sent to specialist clinics. But a lot of first arrive to emergency rooms or are given inadequate therapies.
A charity trustee, in her late seventies, has suffered from the condition 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 pulled because dental professionals misunderstood her pain. She thinks dentists still need much more education. When a sufferer sought help from a support group, it was Chapman who responded. The author recalls calling a helpline during an attack in early 2021; a calm advisor talked me through oxygen treatment and drugs until the attack passed.
Official guidance on management advise that patients are offered high-dose oxygen therapy and/or a anti-migraine medication delivered by nasal spray. No tablets or strong analgesics should be used. Prophylactic choices include verapamil, which reportedly soothes the attacks of well-known individuals.
But leading specialists argue the official guidelines need updating to reflect a more defined clinical process and help general practitioners avoid incorrect prescriptions. For episodic patients, timing is everything: “The duration of the bout dictates the treatment.” Brief bouts with infrequent attacks are managed with acute therapy only. Longer or more severe bouts require preventative medications such as verapamil, sometimes combined with steroids. Many patients also receive a nerve block injection during a bout – an procedure into the side of the skull where the pain is that decreases nerve activity.
The official guidelines need revising to reflect a
