Excruciating Agony: My Fight With the Puzzling Pain of Cluster Headache Syndrome
It began on a gloomy weekday morning in September 2016. I was working as a teacher, attempting to manage a new group of students, when a sharp pain bloomed behind my right eye. This was followed by quick jolts, reminiscent of electric shocks. As each class came and went, the pain subsided and then came back with greater force. Four times that day I handed over a colleague with worksheets and ran to the school bathroom to douse my face with cold water. I took aspirin, but the agony remained unbearable.
The headaches returned frequently that autumn, and once more in the spring, soon establishing an annual pattern. The autumn months were the most severe, then February and March. I could predict the routine: a warning sensation in the morning, early twinges on the train, full-on pain in the classroom by mid-morning. In 2019, a GP finally referred me to a specialist and I was diagnosed with cluster headaches.
Cluster headaches typically begin with severe discomfort behind a single eye that persists up to three hours.
Approximately 1 in 1000 people suffer by the disorder, and males are more often affected. Cluster headaches typically begin with abrupt, severe pain focused on a single eye that peaks within minutes and continues for up to three hours. Episodes come in clusters, every day or multiple times a day, and are associated with tearing eyes, sagging eyelids or facial sweating. There exists the episodic form, which occurs in seasonal cycles; some patients have continuous cluster headaches, defined by the absence of long pain-free periods.
What unites patients is the intensity. One research paper rated the sensation at 9.7 10, more severe than broken bones or pancreatitis. Another discovered 64% of cluster patients experienced suicidal thoughts during bouts; the number fell to four percent when they were not in pain.
One patient, 74, a long-term sufferer from Wales, finds this understandable. Her episodes started when she was two. “I would hurl myself on the ground and hit my head. That was put down to being spoiled,” she says. Her symptoms deteriorated through childhood. Drinking in her adolescence, like many triggers, made things more intense. After drinking alcohol at her school leaving party, she recalls hardly being able to see on the bus home.
Her relatives often interpreted her episodes as intoxicated episodes. Understanding eventually came from her parent and then from her husband, Rod. “I was very fortunate to find such an exceptional person,” she says. Hobbs took clerical work after relocating, but often hid her condition. She was dismissed from one job, in part due to time off during episodes. Her breakthrough identification came in the early 2000s at a specialist neurology center.
Still, the inability to organize daily activities around erratic pain took its toll. She especially hated being unable to plan outings, being seen as unreliable as a co-worker, and even having to be cared for by her children 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 winning tickets for a major concert, only to have an episode inside a facility.
Headaches have been documented across history. “The earliest account of headache comes by way of the Mesopotamians in 4000BC,” write experts in a publication on the subject. They linked the ailment to an evil spirit who attacked his victims' heads.
Ancient medical records propose unusual remedies 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 remedies.
It was a European physician who provided the initial comprehensive description of a cluster-type attack. In his writings, he speaks of a patient “suffering with a very intense headache happening and disappearing daily at fixed hours”.
The disorder were only formally classified by global medical committees in the late 1980s. From the mid-20th century to the 1990s, they were believed to be caused by a issue with a major artery that supplies blood to the head. Leading specialists in diagnosing the disorder note this.
In 1998, scientists published the results of a research project for which they had triggered cluster headaches in patients and observed the episodes in a imaging machine. The results, featured in a major medical publication, showed increased activity of the a brain region, which is in charge for human circadian rhythm, when patients were in discomfort, and a deactivation when they recovered.
Despite such advances, diagnosis remains delayed. Jamie Charteris's symptoms started in 1986 and felt like “a balloon being inflated behind my left eye”. GPs thought he had sinus problems; he underwent multiple surgeries before eventually being correctly identified in 2014, after a doctor looked up his symptoms.
Specialists say delays in diagnosing and managing happen because patients are rarely seen mid-attack. “You're tired and depressed, but not in agony,” one says. He works by ruling out other common headache conditions, such as migraine, before diagnosing the disorder. A detailed patient history is crucial: on which side do symptoms appear? For how long? What time of year? Are there triggers, such as certain foods? Certain features such as redness, sagging eyelids and nasal congestion help confirm 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.
A charity trustee, in her late seventies, has experienced cluster headaches for the majority 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 dental professionals misunderstood her pain. She believes the dental profession still need greater education. When a sufferer sought help from a charity, it was Chapman who replied. I remember calling a support line during an attack in 2021; a reassuring advisor talked them through oxygen therapy and medication until the episode passed.
Official guidance on management recommend that patients are offered high-dose oxygen therapy and/or a anti-migraine medication administered by nasal spray. No tablets or strong analgesics should be used. Preventive choices include a blood pressure medication, which reportedly helps manage the bouts of some people.
But consultant specialists believe the official guidelines need updating to reflect a more defined treatment pathway and help general practitioners avoid misprescribing. For periodic patients, the treatment window is critical: “The duration of the bout determines the approach.” Brief cycles with infrequent attacks are managed with acute therapy only. More prolonged or more severe periods require preventives such as certain drugs, sometimes combined with steroids. Many patients also receive a nerve block injection during a bout – an procedure into the area of the head where the discomfort is that decreases nerve activity.
