Migraine vs Headache: What's the Difference and Why It Matters

"It's just a headache" — four words that have led millions of people to undertreat serious neurological events, and four words that have also sent many headache sufferers down the wrong treatment path. Understanding the difference between migraines and headaches isn't just medical trivia. It determines what kind of care will actually help you.

The Clinical Differences

Headache is a broad term for any pain occurring in the head or neck region. Migraines are a specific neurological disorder characterized by recurring attacks of moderate-to-severe head pain, usually accompanied by additional symptoms. Here's how they typically differ:

Migraines involve complex neurological and vascular changes — cortical spreading depression, trigeminal nerve activation, and altered cerebral blood flow — that distinguish them from ordinary headaches. But there's a third category that trips up both patients and clinicians.

The Category Nobody Talks About: Cervicogenic Headache

A cervicogenic headache (CGH) is a headache that originates from structural dysfunction in the cervical spine — most commonly the upper cervical joints, muscles, and nerves. The problem: cervicogenic headaches can closely mimic migraines. They often present with unilateral pain, moderate-to-severe intensity, nausea, and even light sensitivity. Patients get diagnosed with migraines, put on migraine medication, and never improve — because they don't have a migraine disorder. They have a structural problem in their neck.

The distinguishing features of cervicogenic headache include:

• Pain that consistently starts at the base of the skull or in the neck before spreading to the head
• Headaches that are provoked or worsened by specific neck movements or postures
• Restricted cervical range of motion during or between attacks
• A history of neck trauma, whiplash, or repetitive postural stress (e.g., long hours at a desk)
• Tenderness at the upper cervical joints on physical examination

Research estimates that cervicogenic headaches account for 4–8% of all headaches in the general population — but among chronic daily headache sufferers, the prevalence is far higher. And because CGH is routinely misdiagnosed as migraine or tension-type headache, many patients are undertreated for years.

How Chiropractic Addresses Both

Whether your headaches are true migraines or cervicogenic in origin, the cervical spine plays a central role. For cervicogenic headaches, the spinal origin is definitional — chiropractic care directly targets and corrects the dysfunction causing the headaches. For migraines, the cervical spine is a major amplifying factor: even when a migraine has a primary neurological trigger, coexisting cervical misalignment lowers the threshold, increases frequency, and worsens severity.

Upper cervical chiropractic adjustments — particularly targeting C1 and C2 — restore normal joint mechanics, reduce irritation of the upper cervical nerves, relieve pressure on the brainstem, and normalize the neurological environment that generates both migraine and cervicogenic headache attacks. Multiple clinical trials have confirmed that patients with both condition types experience meaningful reductions in headache frequency and intensity with consistent chiropractic care.

Getting the Right Diagnosis

If you've been diagnosed with migraines but haven't found lasting relief through medication, it's worth asking whether cervicogenic headache — or a combination of both — might be driving your symptoms. A thorough upper cervical evaluation, including range-of-motion testing, postural analysis, and palpation of the cervical joints, can clarify the picture quickly.
