Full-Blown Pain: My Struggle Against the Puzzling Pain of Cluster Headaches

It was a overcast Monday in the morning in September 2016. I worked as a educator, trying to settle a new group of students, when a intense pain sprang behind my one eye. This was followed by rapid shocks, similar to electric shocks. As the school day came and went, the discomfort eased and then came back with increased intensity. Multiple times that day I handed over a colleague with activities and hurried to the school bathroom to soak my face with cold water. I took ibuprofen, but the agony remained unbearable.

The attacks returned frequently that autumn, and once more in the spring, soon establishing an annual pattern. The autumn months were the most severe, then the late winter. I could anticipate the routine: a warning sensation in the morning, early twinges on the commute, full-on pain in class by 9.30am. In late 2019, a GP finally sent me to a specialist and I was diagnosed with cluster headache disorder.

This condition typically begin with severe discomfort around one eye that persists up to several hours.

Approximately one in 1,000 people suffer by the disorder, and men are more often affected. Cluster headaches usually begin with sudden, severe pain around a single eye that reaches its peak within minutes and lasts for up to three hours. Attacks occur in cycles, daily or multiple times a day, and are associated with red or watery eyes, drooping eyelids or facial sweating. There exists the episodic form, which arrives in periodic bouts; others have chronic cluster headaches, defined by the absence of extended symptom-free periods.

What unites patients is the intensity. One research paper scored the sensation at 9.7 10, more severe than broken bones or pancreatitis. A separate found a significant percentage of cluster headache patients experienced thoughts of self-harm during attacks; the number dropped to four percent when they were pain-free.

Val Hobbs, in her seventies, a long-term patient from Wales, finds this understandable. Her episodes started when she was a toddler. “I would hurl myself on the floor and hit my head. That was put down to being a difficult child,” she says. Her condition deteriorated through her youth. Alcohol in her teens, like many triggers, made things worse. After having alcohol at her graduation party, she recalls hardly being able to see on the transport home.

Her relatives often interpreted her attacks as intoxicated episodes. Understanding finally came from her parent and then from her partner, Rod. “I was very fortunate to find such an exceptional person,” she says. Hobbs took office work after relocating, but often concealed her illness. She was dismissed from one job, partly due to absences during episodes. Her breakthrough diagnosis came in 2002 at a national neurology center.

Still, the inability to organize life around unpredictable pain took its effect. She particularly disliked being unable to plan social events, being seen as unreliable as a colleague, and even having to be looked after by her children during the incapacitation caused by the most severe episodes. “It robs you of the simple liberties 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 facility.

Headaches have been documented throughout history. “The first account of headache comes by way of the ancient civilizations in antiquity,” write experts in a publication on the topic. They attributed the ailment to an malevolent entity who afflicted his victims' heads.

Ancient healing records propose bizarre treatments for what some experts would describe as a migraine. In the medieval times, migraine was recognised as a distinct disorder, with therapies including bloodletting to other, more superstitious remedies.

It was a European physician who provided the initial detailed account of a cluster headache. In his writings, he describes a patient “afflicted with a very intense headache happening and vanishing daily at fixed hours”.

The disorder were only officially classified by global headache committees in 1988. From the 1960s to the late 1990s, they were believed to be caused by a problem with a major artery which delivers blood to the head. Leading experts in diagnosing the condition note this.

In 1998, scientists released the results of a research project for which they had triggered attacks in patients and monitored the attacks in a imaging machine. The data, published in a major medical publication, showed increased activity of the hypothalamus, which is in charge for human sleep-wake cycles, when patients were in pain, and a reduction when they recovered.

Despite such advances, diagnosis remains slow. Jamie Charteris's attacks started in the 1980s and felt like “a balloon being inflated behind my one eye”. GPs thought he had sinus problems; he underwent four surgeries before eventually being correctly identified in recently, after a physician researched his complaints.

Neurologists say delays in diagnosis 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 common head pain disorders, such as migraine, before confirming cluster headaches. A detailed history is essential: on which side do signs appear? For how much time? What time of year? Are there triggers, such as alcohol? Specific features such as redness, drooping eyelids and stuffy nose help verify cluster headaches. Once diagnosed, patients may be referred to specialist clinics. But many first go to A&E 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 20s, she had her teeth pulled because dental professionals misunderstood her symptoms. She thinks dentists still need greater awareness. When a sufferer sought help from a support group, it was she who replied. The author recalls calling a helpline during an bout in 2021; a reassuring advisor talked me through oxygen treatment and drugs until the episode eased.

National guidelines on treatment recommend that patients are offered high-dose oxygen therapy and/or a anti-migraine drug administered by nasal spray. No tablets or opioids should be used. Preventive options include verapamil, which reportedly soothes the bouts of some people.

But leading neurologists argue the guidance need revising to reflect a clearer clinical process and help GPs avoid misprescribing. For periodic patients, timing is critical: “The duration of the cycle dictates the approach.” Short cycles with occasional attacks are managed with abortive treatment alone. Longer or more severe bouts require preventives such as verapamil, sometimes combined with corticosteroids. 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.

The official guidance need revising to reflect a
