A cervicogenic headache is head pain that starts from the neck.
After a crash, irritated joints, muscles, and nerves in the upper neck can refer pain into the head, especially when neck movement is stiff or painful.
The headache source is in the neck
Cervicogenic headache is different from a headache that simply happens alongside neck pain. The pain is referred from cervical structures, often the upper neck joints and surrounding soft tissues. StatPearls describes cervicogenic headache as secondary headache, meaning another neck-related problem is driving the head pain. After a crash, rapid neck motion can irritate those structures, so the headache may feel like it starts at the base of the skull and moves toward the temple, forehead, or behind the eye.
What it can feel like after impact
A cervicogenic pattern is often one-sided, tied to neck stiffness, and worsened by certain neck positions. People may notice headaches after driving, desk work, sleeping awkwardly, or turning the head. It may not throb like a migraine, and it may not feel like pressure across the whole head. The key clue is that neck motion and head pain seem connected. If headaches appeared after whiplash-type symptoms, read can whiplash symptoms show up the next day for the delayed mechanism.

A headache after a crash can also come from concussion or another medical issue. Severe headache, confusion, repeated vomiting, fainting, weakness, vision changes, seizure, slurred speech, or worsening symptoms should be treated urgently. The CDC lists headache, dizziness, and confusion among possible mild TBI symptoms. Chiropractic care may fit neck-driven headache patterns after red flags are ruled out, but it should not be used to explain away dangerous head-injury signs.
What an evaluation should connect
A useful evaluation should connect crash mechanics, neck range of motion, headache location, triggers, neurological screening, and prior medical care. The provider should ask whether the headache changes with neck movement, pressure at the base of the skull, posture, or activity. If the pattern fits conservative care, treatment may focus on neck mobility, soft-tissue irritation, and function. If it does not, referral is the safer next step.
Build a headache map
Before the appointment, make a simple headache map. Mark where the pain starts, where it spreads, what neck movements change it, whether pressure at the base of the skull matters, and whether symptoms appear with dizziness, nausea, vision changes, or light sensitivity. Also write the crash date, head position, and whether the headache began immediately or later. That map helps the provider avoid treating all headaches alike. A cervicogenic pattern may fit conservative neck evaluation, but concussion signs, severe headache, or neurological symptoms should change the route. Write down what to bring, what to watch, and which symptom should change the plan.
When to seek urgent care
Do not wait on severe warning signs
Seek urgent medical care if you have severe or worsening pain, weakness, numbness, repeated vomiting, confusion, slurred speech, loss of consciousness, seizure, chest pain, trouble breathing, or other serious symptoms after a crash.
Practical checklist
Symptoms to write down
- When the discomfort started and whether it is improving, repeating, or spreading.
- Which daily activities are harder now, such as sleep, driving, work, or lifting.
- Any urgent symptoms you noticed, even if they later changed.
- Basic accident, insurance, and prior care details if you already have them.
Questions people ask
Direct answers
How is cervicogenic headache different from a concussion headache?
Cervicogenic headache is driven by neck structures, while concussion is a brain injury. Because symptoms can overlap, severe or unusual headaches after a crash should be medically screened.
Can a chiropractor help with cervicogenic headache?
A chiropractor may help evaluate and treat neck-related headache patterns when urgent concerns are absent. The first step is confirming the headache pattern and screening for red flags.
What should I track about the headache?
Track location, onset, neck stiffness, triggers, vision changes, dizziness, nausea, and whether movement changes the pain. Those details guide the next step.
