Sick Note for Headache: When Are Headaches Serious Enough to Stay Off Work?

Sick Note for Headache: When Are Headaches Serious Enough to Stay Off Work?

Almost everyone gets headaches. But there's a world of difference between a mild tension headache and a thunderclap headache, a cluster headache, or a severe migraine attack. When headaches are debilitating, you deserve proper medical support.

TYPES OF HEADACHE AND THEIR IMPACT ON WORK

Tension headaches (the most common type) — typically mild to moderate, usually manageable with over-the-counter pain relief. Unlikely to justify a sick note on their own.

Migraine — moderate to severe, often one-sided, with associated nausea, light and sound sensitivity. A migraine attack can completely incapacitate you for hours to days. This absolutely can justify a sick note.

Cluster headaches — extreme, excruciating pain, often described as the most severe pain a human can experience. During a cluster period, working is essentially impossible.

Medication overuse headache (rebound headache) — headaches caused by taking pain medication too frequently. Can be severe and prolonged.

Headaches from underlying conditions — raised intracranial pressure, meningitis, subarachnoid haemorrhage. These are emergencies — seek urgent care immediately.

WHEN IS A SICK NOTE APPROPRIATE FOR HEADACHE?

A fit note is appropriate when:

● Your headaches are severe enough to genuinely prevent you from working

● You have a medically recognised headache disorder (migraine, cluster headache)

● Your headaches have lasted more than 7 days

● Your work involves screen use, driving, or other activities that significantly worsen your headaches

WHEN TO SEEK URGENT CARE FIRST

Seek emergency care BEFORE contacting Dr Sick if your headache:

● Came on suddenly and is the worst of your life ("thunderclap" headache)

● Is accompanied by fever, stiff neck, or rash

● Is accompanied by sudden vision loss, confusion, or weakness

● Follows a head injury
