Excruciating Agony: My Battle With the Enigmatic Suffering of Cluster Headache Syndrome

It began on a overcast weekday in the morning in the autumn of 2016. I worked as a educator, attempting to manage a new group of students, when a sharp pain sprang behind my right eye. It was followed by quick shocks, reminiscent of lightning bolts. As the school day progressed, the pain subsided and then returned with greater intensity. Multiple times that day I handed over a colleague with activities and ran to the school bathroom to douse my face with cold water. I took ibuprofen, but the pain remained unbearable.

The attacks appeared frequently that fall, and again in spring, soon establishing an annual cycle. September and October were the most severe, then the late winter. I could predict the routine: a warning sensation in the morning, early pangs on the train, full-on pain in class by 9.30am. In late 2019, a GP finally sent me to a neurologist and I was diagnosed with cluster headache disorder.

This condition often start with severe discomfort around one eye that persists for three hours.

About one in 1,000 people suffer by the condition, and men are more often affected. Attacks typically begin with sudden, excruciating pain around a single eye that peaks within a short time and continues for as long as three hours. Episodes come in clusters, daily or multiple times a day, and are associated with red or watery eyes, drooping eyelids or facial perspiration. There exists the episodic form, which occurs in seasonal cycles; some patients have chronic cluster headaches, characterized by the absence of extended symptom-free periods.

What unites patients is the intensity. One study scored the pain at 9.7 10, more severe than broken bones or pancreatitis. A separate found a significant percentage of cluster headache patients reported suicidal thoughts during bouts; the figure dropped to 4% when they were not in pain.

Val Hobbs, in her seventies, a chronic patient from Pembrokeshire, finds this understandable. Her episodes began when she was two. “I would throw myself on the floor and bang my head. That was put down to being a difficult child,” she says. Her condition worsened through her youth. Drinking in her adolescence, like many triggers, made things worse. After drinking alcohol at her graduation party, she remembers barely being able to see on the bus home.

Her relatives often mistook her episodes as drunken episodes. Understanding finally came from her father and then from her partner, Rod. “I was very lucky to find such an exceptional person,” she says. Hobbs found office work after relocating, but often concealed her illness. She was dismissed from one job, partly due to time off during attacks. Her definitive identification came in the early 2000s at a national neurology center.

Nevertheless, the failure to plan daily activities around erratic pain took its toll. She particularly disliked being unable to plan social events, being seen as unreliable as a colleague, and even having to be cared for by her family during the paralysis caused by the most severe episodes. “It robs you of the small freedoms we don't value 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 first description of headache comes by way of the Mesopotamians in 4000BC,” write authors in a book on the topic. They linked the ailment to an evil spirit who afflicted his victims' heads.

Ancient medical records suggest unusual treatments for what modern experts would describe as a migraine. In the middle ages, migraine was identified as a separate condition, with therapies including herbal concoctions to other, more folk cures.

It was a European physician who provided the first comprehensive description of a cluster headache. In his medical observations, he speaks of a patient “suffering with a very intense headache occurring and disappearing each day at fixed hours”.

The disorder were only officially recognised by global headache committees in the late 1980s. From the mid-20th century to the 1990s, they were believed to be caused by a issue with a key artery which delivers blood to the head. Leading experts in diagnosing the condition note this.

In 1998, researchers published the results of a study for which they had induced attacks in patients and observed the episodes in a brain scanner. The results, featured in a prominent journal, showed increased activity of the a brain region, which is responsible for human sleep-wake cycles, when patients were in pain, and a reduction when they recovered.

In spite of such advances, identification remains delayed. Jamie Charteris's symptoms began in 1986 and felt like “a balloon being blown up behind my one eye”. GPs thought he had a sinus issue; he had four surgeries before finally being diagnosed in 2014, after a doctor researched his symptoms.

Neurologists say wait times in diagnosis and treatment happen because patients are seldom seen during an episode. “You're exhausted and low, but not in severe pain,” one says. He works by eliminating other common head pain disorders, such as migraine, before confirming cluster headaches. A thorough history is essential: on which side do signs occur? For how long? What time of year? Are there precipitating factors, such as alcohol? Certain characteristics such as redness, sagging eyelids and nasal congestion help verify cluster headaches. Once identified, patients may be sent to dedicated centers. But a lot of first arrive to emergency rooms or are given unsuitable therapies.

Dorothy Chapman, in her late seventies, has experienced the condition for most of her adult life, although she has been free from an episode since recent years. When she was in her 20s, she had her molars extracted because dentists misunderstood her symptoms. She thinks the dental profession still need much more education. When another patient sought help from a support group, it was Chapman who replied. I remember calling a helpline during an bout in 2021; a calm volunteer talked them through oxygen therapy and medication until the attack passed.

Official guidance on management recommend that sufferers are offered high-dose oxygen and/or a anti-migraine medication delivered by injection. No tablets or opioids should be used. Prophylactic choices include a blood pressure medication, which reportedly helps manage the bouts of some individuals.

But leading neurologists believe the official guidelines need updating to reflect a clearer clinical process and help general practitioners avoid incorrect prescriptions. For periodic patients, timing is everything: “The duration of the bout determines the approach.” Short bouts with occasional attacks are handled with acute therapy alone. Longer or more severe periods require preventative medications such as certain drugs, sometimes combined with corticosteroids. A significant number of patients also receive a nerve block injection during a cycle – an injection into the area of the head where the pain is that decreases nerve activity.

The official guidelines need revising to reflect a
