Doctors Called His Cluster Headaches Migraines for Four Years

The first stretch began in June 2019. Pain gathered behind his right eye and became severe enough that he could not sit still, much less sleep. The eye watered. The nostril on that side closed.

He walked between the bedroom and kitchen until the attack released him, usually after 45 to 90 minutes, then returned to bed knowing it might happen again.

His primary care doctor called it migraine. At an urgent care visit later that month, he was told stress could be tightening the muscles in his neck. He accepted both explanations because the pain stopped after five weeks, and because no one had asked the question that would become important later: whether the attacks were arriving in a repeated daily pattern.

For nine months, nothing happened.

Then the pain returned on the same side. Over the next six weeks, it came once or twice most days. Migraine medication sometimes seemed to coincide with the end of an attack, but the attacks also ended without it, leaving him unsure what the pills had changed. Lying in a dark room did not help.

He paced, pressed his palm against his eye, and tried not to wake his wife.

The notebook

In February 2020, she put a notebook on the kitchen counter and asked him to record each episode. He wrote the month at the top of the page, then noted which side hurt, what happened to his eye and nose, whether he could stay still, and roughly how long the pain lasted. The first page became the hard evidence of a pattern he had struggled to describe during brief appointments.

Right eye. Watering. Nose blocked on right. Could not lie down. Walked until it stopped.

The notebook did not make the pain more credible. It made it harder to compress. Across 38 days, the entries showed attacks clustering together, often after sleep, followed by months without symptoms. Nearly every entry named the right eye.

His wife added small marks beside the nights when his pacing woke her.

A virtual appointment that spring ended with another migraine prescription. The doctor acknowledged the tearing but said migraine symptoms varied. At a follow-up, a different clinician focused on his posture and suggested tension headaches. Neither explanation accounted for the long symptom-free intervals or the agitation during attacks, yet each label carried forward in the medical record and shaped the next visit before he spoke.

By the end of the second cycle, the notebook held 67 entries. He placed it beside his computer during appointments and read from it, but the discussions kept returning to common migraine triggers: food, hydration, screens, sleep. He reduced coffee, changed pillows, and tracked meals. Those efforts generated more notes without explaining why the pain stayed on one side or why it came in concentrated bouts.

Four years of the wrong frame

A third cycle began in October 2021 and lasted seven weeks. He missed nine workdays and used vacation time for several more because his employer required documentation for extended medical leave, which he did not have. Between attacks he could answer email and appear well. During them, he shut himself in a restroom or walked outside until he could speak normally again.

The notebook changed then. Earlier pages had full sentences. The newer entries were blunt: right eye, tearing, pacing, 70 minutes. On one page he wrote that he could not continue through another month of this.

He had no plan to harm himself, but he later said the pain had reduced his thinking to the next attack and the effort required to endure it.

Patient communities sometimes call cluster headache the “suicide disease,” a phrase that reflects reports of extreme pain and psychological distress but can also turn suffering into spectacle. He encountered the term in a public forum in December 2021. More useful than the nickname were descriptions from people who paced instead of lying down, had tearing on the painful side, and experienced attacks in cycles separated by remission.

He took screenshots to his primary care doctor. The response was guarded: internet accounts could lead patients toward the wrong conclusion. Still, after another visit and a six-month wait, the doctor referred him to a headache specialist. The referral did not resolve the current cycle.

It ended before the specialist appointment arrived.

In March 2023, nearly four years after the first episode, the attacks returned. His insurer initially questioned whether a specialist visit was medically necessary, and the doctor’s office resubmitted the request. The delay was five weeks. He paid $286 for another urgent care visit during that period and received the same broad label, migraine, on the discharge summary.

The pattern gets a name

The specialist opened the notebook before discussing medication. She traced the months with attacks and the blank spaces between them, then asked about the fixed side, the watering eye, the blocked nostril, and his need to move. She also asked whether he became sensitive to light or nauseated, symptoms earlier clinicians had emphasized. Those happened occasionally, but they were not the center of his experience.

“This pattern is consistent with cluster headache,” she told him.

The conclusion did not come from a new scan or a single revealing test. It came from the accumulated timing and features already present in the notebook, considered together rather than separated across visits. The specialist explained that cluster headache belongs to a group of headache disorders associated with one-sided pain and same-side autonomic symptoms, and that the restlessness he had treated as panic was part of the pattern she was evaluating.

She prescribed a different acute treatment, including oxygen for home use, and a preventive treatment for the active cycle. Obtaining the oxygen took three more weeks because coverage and supply arrangements moved through separate offices. The equipment arrived with an $84 charge he had not expected. He paid it rather than risk another delay.

During the next attack, he used the treatment as prescribed and wrote the result in the notebook. The pain eased after 18 minutes. It did not vanish forever, and later attacks varied, but the first response was different enough that he checked the kitchen timer twice before recording it. Within two weeks, he had missed no further workdays.

Relief did not correct the preceding four years. His medical record still contained migraine and tension headache entries, and he continued receiving automated reminders tied to earlier prescriptions. At a follow-up, the specialist discussed the possibility that future cycles could change in length or frequency. Certainty remained limited to what had happened so far.

The notebook stayed on the kitchen counter after the cycle ended in May 2023. For months, its last written page showed the same short entry: right eye, oxygen, 18 minutes. The next page was blank.

Questions people ask

Why can cluster headaches be mistaken for migraines?

Both can involve severe one-sided head pain, tearing, and sensitivity to light. In this story, clinicians repeatedly focused on pain intensity and familiar migraine symptoms while giving less weight to the fixed side, pacing, repeated daily attacks, and symptom-free months recorded in the notebook.

What finally changed the diagnosis in this story?

No single symptom settled it. The specialist reviewed four years of entries together and saw a recurring combination: right-sided pain near the eye, same-side tearing and congestion, inability to stay still, attacks lasting under two hours, and cycles separated by long remissions.

Did getting a name lead to immediate relief?

No. The specialist changed the treatment plan, but insurance review and equipment supply added three weeks before oxygen reached his home. The first response was faster than he had experienced with earlier treatments, although later attacks still varied and the possibility of another cycle remained.

What happened after the active cycle ended?

He returned to work without knowing when the headaches might recur. Old migraine labels remained in parts of his record, and the specialist could not promise a permanent remission. The morning after his last recorded attack, he left the notebook on the kitchen counter and went to work.
