A 52-year-old man presents with a new, severe, constant headache located at the back of the head with slight vision changes; paracetamol has not helped. What is the most appropriate action?

• A. Take paracetamol again
• B. Eye strain
• C. Return to bed
• D. Refer him immediately to his GP for further investigation

Answer: (D)

A new, severe, persistent headache with vision changes is a red-flag presentation that suggests something serious could be happening in the brain. In this scenario, urgent medical evaluation is needed to rule out dangerous conditions such as intracranial bleeding, a mass, meningitis, or other acute processes. Paracetamol alone isn’t enough when red flags are present, and delaying assessment can miss a treatable cause. Refer him immediately to his GP for further investigation so they can perform a focused history and examination, and arrange appropriate tests (often urgent imaging or specialist referral) as indicated. The other options don’t address the potential seriousness of the symptoms: taking more paracetamol delays diagnosis, eye strain doesn’t explain a new, severe headache with vision changes, and returning to bed postpones important evaluation.
