Excruciating Suffering: A Personal Fight With the Mysterious Pain of Cluster Headache Syndrome

It was a dreary weekday in the morning in the autumn of 2016. I worked as a teacher, attempting to manage a new group of students, when a intense pain erupted behind my right eye. It was followed by rapid shocks, like electric shocks. As the school day progressed, the pain subsided and then came back with greater intensity. Four times that day I handed over a colleague with activities and hurried to the staff bathroom to soak my face with cold water. I took paracetamol, but the agony remained unbearable.

The headaches appeared frequently that fall, and once more in the spring, soon forming an annual pattern. The autumn months were the most severe, then February and March. I could predict the pattern: aura in the shower, early twinges on the train, full-on agony in the classroom by 9.30am. In 2019, a doctor eventually referred me to a specialist and I was given a diagnosis with cluster headache disorder.

This condition typically start with severe pain behind one eye that lasts for several hours.

Approximately one in 1,000 people suffer by the condition, and men are more frequently diagnosed. Attacks typically begin with sudden, excruciating pain around one eye that reaches its peak within a short time and lasts for up to three hours. Episodes occur in cycles, daily or several times a day, and are associated with tearing eyes, drooping eyelids or face perspiration. I have an episodic type, which occurs in periodic cycles; others have chronic cluster headaches, defined by the lack of long pain-free periods.

What connects sufferers is the intensity. One study rated the sensation at 9.7 10, more severe than bone fractures or other conditions. A separate found 64% of cluster patients reported thoughts of self-harm during attacks; the number fell to four percent when they were not in pain.

Val Hobbs, in her seventies, a chronic sufferer from Wales, finds this understandable. Her episodes began when she was two. “I would throw myself on the ground and bang my head. That was attributed to being a difficult child,” she says. Her condition deteriorated through childhood. Alcohol in her adolescence, like several causes, made things more intense. After drinking alcohol at her school leaving party, she remembers barely being able to see on the transport home.

Her relatives often mistook her attacks as intoxicated behavior. Understanding eventually came from her parent and then from her partner, her spouse. “I was very fortunate to find such an exceptional person,” she says. Hobbs took office work after relocating, but often concealed her condition. She was fired from one job, in part due to absences during episodes. Her breakthrough identification came in the early 2000s at a specialist hospital.

Still, the failure to organize life around unpredictable attacks took its toll. She especially 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 incapacitation caused by the worst episodes. “It robs you of the simple freedoms we don't appreciate until they're gone,” she says. She remembers winning tickets for a major concert, only to have an attack inside a facility.

Headaches have been documented across history. “The earliest account of headache originates from the Mesopotamians in 4000BC,” write experts in a publication on the subject. They attributed the ailment to an evil entity who afflicted his sufferers' heads.

Ancient medical records suggest unusual treatments for what modern experts would classify as a migraine. In the middle ages, migraine was identified as a distinct condition, with therapies ranging from bloodletting to other, more superstitious remedies.

It was a European physician who provided the first detailed account of a cluster headache. In his writings, he speaks of a patient “afflicted with a very severe headache occurring and disappearing daily at specific hours”.

The disorder were only formally recognised by global medical societies in 1988. From the 1960s to the 1990s, they were thought to be caused by a issue with a key blood vessel that delivers blood to the head. Leading specialists in diagnosing the condition explain this.

In 1998, researchers released the findings of a study for which they had induced cluster headaches in patients and observed the episodes in a brain scanner. The data, featured in a major journal, showed increased activity of the a brain region, which is in charge for human circadian rhythm, when patients were in pain, and a deactivation when they felt better.

In spite of such progress, identification remains delayed. One man's symptoms started in 1986 and felt like “a balloon being inflated behind my left eye”. Doctors thought he had a sinus issue; he had four operations before finally being diagnosed in recently, after a physician researched his complaints.

Neurologists say delays in diagnosing and treatment happen because patients are rarely seen during an episode. “You're tired and low, but not in agony,” one says. He proceeds by ruling out other common headache conditions, such as tension-type headache, before confirming cluster headaches. A detailed history is crucial: on which part of the head do signs occur? For how long? What time of year? Are there triggers, such as certain foods? Specific features such as redness, sagging eyelids and stuffy nose help verify cluster headaches. Once identified, patients may be sent to specialist centers. But a lot of first arrive to emergency rooms or are given unsuitable therapies.

Dorothy Chapman, in her late seventies, has experienced cluster headaches for the majority of her life, although she has been free from an episode since recent years. When she was in her twenties, she had her teeth pulled because dental professionals misunderstood her symptoms. She thinks dentists still need much more education. 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 volunteer talked them through oxygen treatment and drugs until the attack passed.

National guidelines on management recommend that patients are offered high-dose oxygen therapy and/or a anti-migraine medication administered by nasal spray. No oral painkillers or opioids should be used. Preventive options include a blood pressure medication, which apparently soothes the attacks of some people.

But consultant neurologists believe the official guidelines need updating to reflect a clearer clinical process and help general practitioners avoid misprescribing. For periodic patients, the treatment window is critical: “The duration of the cycle determines the treatment.” Short cycles with occasional episodes are managed with abortive therapy only. More prolonged or more intense periods require preventives such as certain drugs, sometimes combined with corticosteroids. Many patients also receive a greater occipital nerve block during a bout – an injection into the side of the skull where the discomfort is that decreases nerve activity.

The national guidance need revising to reflect a
