Neck Anatomy and the Head

Most people think of a headache as a problem inside the head. Some headaches are not. They start in the neck and are felt in the head, because the nerves of the upper neck and the nerves of the head share pathways.

These are called cervicogenic headaches, from the medical term for the neck. They are one of several headache types, and they are the type most likely to respond to physical treatment of the neck.

This article explains how they differ from other headaches, how a clinician assesses them, and which warning signs mean a headache needs a physician rather than a therapist.

A Headache With a Source Elsewhere

A cervicogenic headache is a headache caused by a problem in the upper neck. The joints, muscles and nerves at the top of the spine refer pain upward into the back of the head, the temple or behind the eye.

Referred pain is common in the body. Heart problems can be felt in the arm, and hip problems can be felt in the knee. A cervicogenic headache follows the same principle: the source is in one place and the pain is felt in another.

The practical consequence is important. Treating the head will not fix a headache whose source is in the neck. The assessment has to find the source.

How It Differs From Other Headaches

Several common headache types can feel similar at first. The differences show up in the pattern.

A person can have more than one type. Someone with migraines can also develop a neck-driven headache, and sorting out which one is happening on a given day is part of the assessment.

Why Desk Work Feeds Neck-Driven Headaches

Long periods with the head forward over a screen load the joints and muscles at the top of the neck. The head is heavy, and when it sits in front of the shoulders, the muscles at the back of the neck hold it up for hours.

Over a workday that sustained load can irritate the upper neck and trigger a headache that builds through the afternoon. People often notice that the headache is worse on heavy screen days and better on weekends or holidays.

Phones add to it. Looking down at a phone flexes the neck further than looking at a desktop monitor, and many people spend long stretches that way.

What the Assessment Looks For

A physical therapy assessment for headaches begins with history. The clinician asks where the headache starts, how it spreads, how long it lasts, what triggers it and what eases it. A headache that consistently starts at the base of the skull on one side and builds with neck posture points one way. A throbbing headache with visual changes points another.

The physical examination tests the neck: how far it moves in each direction, whether particular movements reproduce the headache, and how the joints of the upper neck respond to gentle pressure. A useful finding is when pressing on a specific spot at the top of the neck reproduces the person’s familiar headache.

The clinician also checks posture, shoulder blade control and the endurance of the deep neck muscles, which support the head over long periods.

Warning Signs That Need a Physician First

Some headaches are emergencies. These signs mean seeking medical care rather than booking physical therapy:

• A sudden, severe headache that peaks within a minute.
• Headache after a head injury.
• Headache with fever, stiff neck and feeling unwell.
• Headache with weakness, numbness, slurred speech, confusion or vision loss.
• A new headache pattern after age 50, or one that keeps getting worse.

A physical therapist screens for these signs at the first visit and refers anyone who has them. Physical therapy for headaches assumes the serious causes have been ruled out.

What Treatment Usually Involves

When the neck is the source, treatment usually combines hands-on care with exercise. Manual therapy to the joints and muscles of the upper neck can ease pain in the short term. Exercises that build endurance in the deep neck muscles and the muscles around the shoulder blades address the load over the longer term.

Workstation changes are part of it. Raising a monitor so the eyes meet the top third of the screen, bringing the keyboard close and taking short breaks to move the neck reduce the sustained load that triggers the headache.

Results vary from person to person, and some people need medical treatment alongside physical therapy. A reasonable plan sets clear measures, such as headache frequency and intensity, so progress can be judged rather than guessed.

How People in Northwest Arkansas Find Care

People searching for help with neck-driven headaches tend to look for outpatient clinics close to home or work, since treatment involves repeat visits. In Northwest Arkansas, Advanced Physical Therapy is one outpatient practice with clinics in the region that treats headaches among other conditions, and directions to one location are available through the Rogers clinic listing. Readers who want more background can find a clinical overview of headache types that covers the different patterns in more depth.

Keeping a Headache Diary

A simple diary makes the first assessment far more useful. For two weeks, note:

• When each headache started and how long it lasted.
• Where it started and where it spread.
• What you were doing beforehand: screen work, driving, sleep, stress.
• What eased it.

Patterns that are invisible day to day become obvious over two weeks, and they help the clinician identify the headache type quickly.

Workstation Changes That Reduce Neck Load

Because sustained posture is the most common trigger, the workstation is often where change starts. Small adjustments reduce the load the upper neck carries over a day.

Laptops deserve a special mention. A laptop’s screen and keyboard are attached, so either the screen is too low or the keyboard is too high. For people who work on a laptop all day, a stand with a separate keyboard and mouse is one of the most useful changes they can make.

Breaks matter as much as setup. Even a perfect workstation becomes a problem when a person sits motionless at it for four hours. A short pause to stand, turn the head gently in each direction and roll the shoulders resets the load.

Sleep Position and Morning Headaches

Some people notice their neck-driven headaches are worst on waking. Sleep position is worth a look in that case.

Sleeping on the stomach turns the head fully to one side for hours, which loads the upper neck joints. A pillow that is too high or too flat for a side sleeper bends the neck sideways all night. Back and side sleeping with a pillow that keeps the head level with the spine are generally easier on the neck.

Changing sleep position is slow, because people return to their habitual position once asleep. A pillow that makes the preferred position comfortable usually helps more than trying to force a new one.

Reading or scrolling a phone in bed before sleep adds to the problem. Propped up on pillows with the head bent forward over a screen, the neck repeats the same sustained position that triggers daytime headaches, just at the end of the day instead of the middle of it.

It also helps to set realistic expectations about time. Neck-driven headaches often develop over months or years of sustained posture, and they rarely disappear after a single visit or a single change. Most people notice that headaches become less frequent or less intense first, before they stop altogether, so tracking frequency in the diary is a better measure of progress than waiting for the last headache.

The Short Version

Some headaches start in the neck. They tend to begin at the back of the head on one side and build with neck posture. A clinician identifies them by testing the neck and reproducing the familiar headache. Warning signs need a physician first. When the neck is the source, treatment focuses on the neck, not the head.
