Short answer: Headaches after a car accident often start in the neck, not in the head itself. Clinicians call that pattern a cervicogenic headache, which simply means the pain is referred from irritated joints, ligaments, or muscles in the upper neck. Many of these headaches are worth a careful exam once serious injury has been ruled out. A smaller set of warning signs means you should go to the emergency room first.
The crash on US-50 or MD-197 may have been a few days ago. The car is in the shop, the insurance calls have started, and now a dull ache begins at the base of your skull and creeps toward your temple or behind one eye. I hear this story often in our Bowie office. Those headaches are easy to brush off as stress or a poor night of sleep, and sometimes that is all it is. Often, though, the pain is coming from your neck.
Why do headaches after a car accident often start in the neck?
In a collision, even a lower-speed one, your head and neck can move forward and back before the muscles have time to brace. That motion can strain the small joints, ligaments, and muscles of the upper cervical spine — the top vertebrae just below the skull.
Those upper neck structures share nerve pathways with the head. When they are irritated, the brain can perceive the pain as a headache rather than as neck pain. That is what "cervicogenic" means: a headache that originates in the neck.
MedlinePlus notes that falls or accidents, including car accidents, are a common cause of neck pain, and that whiplash is a soft-tissue injury to the neck, also called a neck sprain or strain. That does not mean every post-crash headache is coming from the neck. Migraine, a concussion, or another medical cause can look similar, which is why a history and exam matter, and why some symptoms belong in the emergency room first.
What does a cervicogenic headache feel like?
Everyone is a little different, but neck-related headaches after a crash often share a pattern:
- Pain that starts at the back of the head or upper neck and spreads forward
- Usually one-sided, and often the same side each time
- Neck stiffness or less ability to turn your head
- Headaches that get worse with certain neck positions, such as looking down at a phone or checking a blind spot
- Tenderness at the base of the skull
- Pain that may travel into the shoulder on the same side
These symptoms can show up the same day, or they may appear hours or days later as inflammation builds and adrenaline wears off. MedlinePlus also notes that concussion symptoms, including headache or neck pain, may not start right away and can begin days or weeks after the injury. Car accidents are one of the causes it lists. That delay is one reason I encourage people to get evaluated even when they felt fine at the scene. If you want a broader picture of symptoms that can arrive later, I walk through that in delayed whiplash symptoms after a car accident.
A neck-related headache can also be mistaken for an ordinary tension headache. The difference we look for is a clear link to neck motion, posture, or tenderness, not just stress at the end of a long day.
When should a headache after a crash send you to the ER first?
A chiropractic visit is not a substitute for emergency care. Go to the emergency room or call 911 if a headache after a car accident comes with any of the following:
- A sudden, severe headache, or "the worst headache of your life"
- A headache that gets worse or does not go away
- Loss of consciousness at any point, even briefly
- Confusion, unusual drowsiness, or trouble waking up
- Vision changes, double vision, or slurred speech
- Repeated vomiting or nausea
- Weakness, numbness, or loss of coordination in the arms or legs
- Seizures
- A fever with a stiff neck
- Loss of bowel or bladder control
MedlinePlus advises getting medical help right away for a headache after a blow to the head, or for a headache with a stiff neck, fever, confusion, or loss of consciousness. Its head injuries topic also lists a worsening or persistent headache, repeated vomiting, seizures, an inability to wake up, slurred speech, weakness or numbness, loss of coordination, and increasing confusion as warning signs that need help immediately. Once those concerns have been checked and cleared, a neck-focused evaluation is a reasonable next step.
How do I evaluate post-accident headaches?
At Total Wellness Chiropractic in Bowie, an evaluation after a car accident starts with listening. I ask how the crash happened, where you were seated, which direction the impact came from, and when the headaches began. Then I look at:
- How far and how comfortably you can turn, tilt, and bend your neck
- Joint motion in the upper cervical spine
- Muscle tension in the neck, upper back, and shoulders
- A neurological screening, including reflexes, strength, and sensation
- Posture and everyday movements that may be adding strain
If anything in the exam suggests you need imaging or a referral to another provider, I will tell you directly. We have on-site X-ray when it is appropriate, and I will also refer out when the findings point that way. You can see how this kind of visit usually unfolds in our guide to common car accident injuries a chiropractor evaluates.
If chiropractic care is not the right next step — for example, if the headache pattern looks more like a medical issue, or if you need a neurologist or your primary doctor first — I would rather say so and help you get there than keep you in a plan that does not fit.
What can care look like if the neck is involved?
When the neck is a likely contributor, a plan is built around supporting comfortable motion and reducing strain on the irritated tissues. Depending on your exam, that may include:
- Gentle chiropractic adjustments to the cervical and upper thoracic spine
- Soft-tissue work for tight, guarded muscles
- Rehab exercises to support deep neck strength and posture
- Hydromassage to help muscles relax between visits
- Practical guidance on sleep position, screen height, and desk setup
The goal is to help your neck move more comfortably so it may contribute less to your headaches. Results vary from person to person, and I reassess as we go rather than locking you into a one-size-fits-all plan. If home exercise or a referral is the better option, that is the recommendation I will make.
Why does a clear record matter after a crash?
If you were hurt in an accident, a clear, dated record of your symptoms and care helps your providers track progress. It is also the kind of record insurers typically look for. Maryland law requires auto insurers to offer Personal Injury Protection, or PIP, which may reimburse reasonable and necessary medical expenses after a crash, regardless of who caused the accident. Coverage can be limited or waived, and claims need to be filed properly and promptly, so the specifics belong with your insurer or a licensed Maryland attorney. We document care; we do not give legal advice. Our guide to Maryland PIP insurance and chiropractic care explains how that generally works.
If you are still deciding when to come in, how long after a car accident you should see a chiropractor may help you think through the timing.

Frequently Asked Questions
Is it normal to get headaches days after a car accident?
Yes, it is common for headaches and neck stiffness to show up hours or days after a collision. A delayed headache still deserves an evaluation, and any red-flag symptoms listed above need emergency care first.
How do I know if my headache is coming from my neck?
Neck-related headaches often start at the base of the skull, sit on one side, and get worse with certain neck movements or positions. A hands-on exam is the best way to sort that out, because migraine, concussion, and other causes can overlap.
Should I see a chiropractor or a medical doctor first?
If you have any red-flag symptoms, start with the emergency room or your medical doctor. If those have been ruled out and your headache seems tied to neck stiffness or motion, a chiropractic evaluation can be a helpful next step, and I coordinate with other providers when needed.
Can a lower-speed crash still cause a neck-related headache?
Yes. You do not need a dramatic, high-speed impact for the neck to be strained. If symptoms appeared after the crash, they are worth evaluating, even if the vehicle damage looked minor.
How soon should I get evaluated?
Sooner is usually more useful, both for your comfort and for a clear timeline in your records. If the accident was a week or two ago and the headaches are still there, it is not too late to be seen.
Will my auto insurance help with the visit?
It might, depending on your policy. Many Maryland drivers have PIP on their own auto insurance, but some have limited or waived that coverage. Ask your insurer what you have, what forms they need, and how visits are handled. We can document the care; coverage decisions are made by the insurer.
What if chiropractic care is not the right option?
Then I will say so. Some headaches need medical evaluation, imaging, or another specialist first. If an exercise plan or a referral is the better path, that is what I will recommend.
