Tension headaches are usually neck problems in disguise

One of the most common things people come in for is a headache they’ve had on and off for years — band-like pain across the temples and forehead, often worse at the end of a work day, relieved temporarily by ibuprofen but never truly gone.

Most of these aren’t “tension headaches” in the way people mean. They’re cervicogenic — meaning they originate in the neck, not the head.

How the upper neck refers pain to the head

The trigeminal nerve — the main sensory nerve of the face and head — shares a nucleus in the brainstem with the nerves from the top three cervical segments (C1, C2, C3). This shared wiring is called the trigeminocervical nucleus, and it’s why irritation in the upper neck gets interpreted by the brain as pain in the forehead, temples, or behind the eye.

When those upper cervical segments are restricted — which is extremely common in anyone who spends hours at a desk — the joint capsules and surrounding muscles send a steady stream of mild irritation signals into that shared nucleus. The brain interprets it as a headache, because that’s how those signals read when they come through that pathway.

How to tell if yours is cervicogenic

A few markers:

• Pain is usually one-sided or strongly side-dominant — true primary tension headaches are typically bilateral
• Tied to posture or neck position — worse after long periods at the computer, better after sleep
• Often triggered by neck movement or prolonged holding of a head position
• Rarely comes with nausea, light sensitivity, or aura (which would suggest migraine instead)
• Pressing on specific spots in the upper neck reproduces the headache

If two or three of those sound familiar, the odds your headache is driven by the neck are high.

What actually works

The good news: cervicogenic headaches respond well to targeted manual therapy of the upper cervical joints combined with specific exercises for the deep neck flexors — the small stabilizers that get shut down by hours of slumped computer posture.

A typical patient with years of “tension headaches” sees meaningful reduction in frequency and intensity within three to six sessions, and most can become largely headache-free with a consistent home exercise program. It’s one of the most satisfying presentations to treat because the results tend to be clear and lasting — not “feels better for a day” but actually fewer and less intense headaches over weeks.

What to rule out first

Not every headache is cervicogenic. Sudden severe headaches, headaches with vision changes, numbness, or fever, headaches after head trauma, or headaches that wake you from sleep all need a medical workup first. Chiropractic care isn’t a substitute for ruling out those red flags — it’s what comes after we’ve established that this is mechanical, not medical.

For the everyday “my head hurts at the end of every workday” pattern, a quick assessment usually tells us exactly what’s driving it, and the fix is usually simpler than people expect.
