From Exploration to Assumption in Headache Care

Modern headache assessment is thorough, structured, and standardised. Clinicians take detailed histories, apply diagnostic criteria, exclude red flags, and use imaging when appropriate. In many cases, this leads efficiently to a migraine diagnosis.

Within this careful approach, one element has diminished: skilled physical examination.

This subtle reduction in emphasis on examination sets the stage for important questions about current practice.

When Diagnosis Replaced Exploration

Previously, clinical medicine balanced history and examination to understand conditions. In headache care, diagnosis now relies mostly on history.

After the criteria are met and serious issues are ruled out, doctors may skip a detailed physical examination, often using quick checks to confirm suspicions rather than pursuing further evaluation.

This shift reflects assumptions: migraine is neurological, structural abnormalities are uncommon, imaging is normal, and physical findings are thought to add little.

The important word here is assumed.

The Consequence of Assumption

Patients commonly report neck discomfort, stiffness, or pain preceding headache onset. Despite this, many have never undergone a detailed cervical assessment.

Clinicians may avoid thorough examination, worrying about attributing symptoms to musculoskeletal causes or challenging established diagnoses. Caution is appropriate, but skipping examination entirely is not.

Good clinical reasoning needs information. You can’t find what you don’t look for.

Technology and the Changing Role of Examination

Imaging has changed doctors’ expectations. Normal scans reassure, but mainly rule out structural problems. They reveal little about system sensitivity or pain processing.

Headache disorders are rarely disorders of visible structure. They are disorders of system behaviour.

The nervous system responds to incoming signals, not radiological appearances.

Examination as Hypothesis Testing

Physical examination need not prove causes. Their value is in exploring whether external signals influence a sensitised system.

Findings suggest possibilities, not diagnoses, and help explain patient differences.

Given trigeminocervical convergence, in which cervical and trigeminal afferents share pathways, such exploration is biologically plausible.

The aim isn’t to replace diagnosis but to add more depth to it.

Moving Beyond Either Or Thinking

One ongoing challenge is the idea that you have to pick between explanations: migraine or cervical headache.

Biology rarely operates in binaries. Multiple contributors may coexist within a sensitised nervous system. Finding a factor that can be changed doesn’t rule out migraine; it helps us understand how migraine shows up in each patient.

Restoring Curiosity to Practice

Restoring meaningful examination shifts the focus from confirmation to exploration, from exclusion to understanding, and from inevitability to possibility.

Examinations are a way to show curiosity and ask better questions through close observation.

A Necessary Rebalancing

Headache medicine has benefited greatly from clearer diagnoses and new technologies. But moving forward might mean finding a better balance between classification, imaging, and hands-on examinations.

Clinicians should commit to restoring careful, hands-on examination in headache care, making it an essential part of practice for each patient.

Examinations show curiosity in action and may be where real care starts.
