Headaches after a car accident

Person with a new headache and neck discomfort after a car accident without a visible direct head strike.
A post-crash headache deserves a medical-first safety check even when no direct head impact is remembered. Headache location or timing alone does not identify the cause.

Concussion and neurological danger signs require emergency care

Seek emergency help right away for any of these signs:

  • Worsening confusion or unusual behavior.
  • Loss of consciousness or a seizure.
  • Repeated vomiting or slurred speech.
  • New weakness or numbness, or unequal pupils.
  • Trouble staying awake or major balance problems.
  • A rapidly worsening headache.

The CDC lists concussion signs and danger signs(opens in a new tab). The MedlinePlus headache guide(opens in a new tab) also flags sudden, explosive, or "worst ever" headaches. Neurological headaches also need immediate medical care.

If head injury is possible, ask a medical provider to check you for a concussion. A chiropractic office does not provide concussion or neurological care.

Describe the timing, location, and related symptoms

Write down:

  • When the first headache began.
  • Where it starts and whether it travels.
  • Whether it is pressure, throbbing, sharp, or unfamiliar.
  • Whether light, sound, neck movement, exertion, screens, or position changes it.
  • Whether nausea, dizziness, confusion, vision change, or balance trouble occurs.
  • Whether it is improving, stable, or worsening.
  • What medical evaluation has already occurred.

Avoid forcing the symptom into a label. "Different from my usual migraine" is important information.

When neck-related evaluation may be considered

Some headaches come with neck stiffness or begin near the base of the skull. Even so, the crash history and a nerve check come first — danger signs have to be ruled out before anything else makes sense. If the problem then looks like a muscle or joint issue, an exam may look at the neck and nearby function.

Read whiplash after a crash and neck pain after a crash. How accident care works here covers the visit itself, and the full symptom index is there if something else changed too. If no collision occurred, use the everyday headache guide. If the head was struck, read concussion warning signs first.

Pain relief does not rule out a medical concern

A symptom that eases for a while can still need a check. Follow emergency or medical instructions. If a provider checked you for a concussion and said to wait, do not go back to driving, work, or sports yet.

Frequently asked questions

Choose the care setting that matches the symptoms

Danger signs come first — call 911.
Once a medical provider has looked at the head-injury question, a muscle-and-joint headache is a fair thing to ask about. Call (740) 876-8394 and describe where it starts and what makes it worse; you don't need to have decided what kind of headache it is. Prefer to be called back? Request a callback for scheduling basics.
