A headache after a car accident is not something to power through, especially in the first days. Sometimes it is muscular, like a neck sprain from whiplash. Sometimes it is a brain injury signal, including concussion or bleeding that needs urgent evaluation.
According to CDC, headaches are a common symptom of mild traumatic brain injury (mTBI) and concussion. NIH (NINDS) explains that a TBI can follow a forceful bump or jolt to the head or body, which can happen in a crash even without a direct head strike.
Here is how we approach it as trial lawyers: we start with safety and medicine, then we build the proof while it is still available. We are not built for volume. We are built for leverage. Speed + evidence preservation + insurer-insider knowledge + trial-ready preparation = The Babcock Benefit.
In headache cases, leverage often comes from locking down the timeline early: when symptoms started, how they changed, and what the first providers documented. That early record can prevent the defense from rewriting your story later. Insurer-insider knowledge means we understand how claims get evaluated, how adjusters look for “gaps,” and how defense doctors attack causation.

Why a Post-Crash Headache Matters
After a collision, headache can come from more than one mechanism. A rapid back-and-forth neck movement can irritate joints, ligaments, and muscles, and that neck injury can refer pain into the head. Johns Hopkins Medicine notes that whiplash can involve muscles, discs, nerves, and tendons, and it commonly follows motor vehicle crashes.
Headache can also be part of a concussion picture, sometimes with light sensitivity, dizziness, trouble focusing, sleep disruption, or mood changes. Mayo Clinic explains that concussion symptoms may include headache and trouble concentrating, and that some people experience post-traumatic headaches for days to weeks.
Leverage Note: This is why we push for prompt evaluation and a clean symptom timeline. Early documentation makes it harder for an insurer to argue, months later, that the headache was “just stress” or “pre-existing.”
Red Flags That Should Trigger Urgent Medical Evaluation
Some headaches are warning signs, especially when they worsen, change character, or come with neurologic symptoms. CDC HEADS UP lists danger signs after a concussion, including a headache that gets worse and does not go away, slurred speech, weakness, numbness, or decreased coordination.
| When a headache after a crash is an emergency | Why it matters |
|---|---|
| Headache that rapidly worsens, or is “the worst headache” you have had | Potential bleeding or other serious complication should be ruled out promptly. |
| New confusion, marked drowsiness, or inability to stay awake | Concerning for brain injury complications that need urgent assessment. |
| Weakness, numbness, speech changes, vision changes, or seizures | Neurologic deficits require immediate evaluation and documentation. |
| Repeated vomiting or worsening dizziness | Can accompany more significant concussion or intracranial injury. |
Bleeding around the brain can develop after head trauma, and symptoms may appear right away or later. Cleveland Clinic explains that subdural hematoma symptoms like headache and slurred speech can develop immediately or days to months after an injury, and it can be life-threatening.
Common Medical Explanations We See Linked to Crash Headaches
Many post-crash headaches fall into a few categories, and more than one can be present at the same time. The point is not to self-diagnose. The point is to treat the headache as a signal worth evaluating and documenting.
- Concussion or mild TBI: MedlinePlus describes concussion as a brain injury that can follow a hit to the head or body and can affect brain function. Symptoms can include headache, dizziness, and trouble thinking clearly.
- Post-traumatic headache and persistent symptoms: Mayo Clinic notes that headaches after a concussion often feel like migraines or tension-type headaches, and may relate to a neck injury occurring at the same time.
- Whiplash-associated neck injury: AAOS OrthoInfo explains that neck sprains and strains can occur after the neck is bent or rotated abnormally, which matches crash mechanics.
- Intracranial bleeding: Even if rare, it is high stakes. Cleveland Clinic emphasizes not ignoring severe headaches after trauma because head injuries can have serious complications.
Leverage Note: That is what we mean by leverage, we do not let the first record become the defense narrative. If EMS, urgent care, or the ER chart misses “head impact” or “headache started that night,” insurers will use the silence against you.
What To Do in the First Week After a Crash Headache
Start with medical care and follow your provider’s advice. If you have red flags, seek urgent evaluation, and do not drive yourself if you are dizzy or confused. CDC explains when to seek care after a mild TBI or concussion and emphasizes follow-up if symptoms do not go away.
Write down a simple timeline: when the headache started, what makes it worse, and any associated symptoms like nausea, light sensitivity, trouble concentrating, or sleep changes. Keep copies of discharge instructions and follow-up plans, and do not “tough it out” to the point you skip appointments, because missed care creates gaps that insurers exploit.
If your provider suspects concussion, be careful with return-to-activity decisions and avoid another head injury. CDC notes that repeated mild TBIs can lead to longer recovery or more severe symptoms, including ongoing headaches.
What We See in Practice
What we see is that insurers often try to downgrade a head injury into “just a headache” if there is any delay in care or any missing documentation. We also see defense arguments that headaches are “common” and therefore unrelated, unless the record shows the change from baseline and ties it to the crash mechanism.
We also see a predictable playbook: focus on property damage, point to a normal CT, then suggest the symptoms must be anxiety or pre-existing. A normal scan can be important and reassuring, but it does not automatically end the analysis of concussion symptoms. What wins these cases is a consistent, well-documented medical timeline and preserved evidence connecting crash forces to the onset of symptoms.
Evidence That Matters in a Louisiana Head-Injury Claim
Medical proof is only one piece. Liability and damages still have to be proven, and insurers do not pay fairly when evidence is thin. If your crash involved a commercial vehicle or rideshare, additional preservation issues can show up fast.
- Crash proof: photos of the vehicles and scene, 911 calls if any, tow and repair records, and any dashcam footage.
- Symptom timeline proof: your first report of headache, nausea, dizziness, sleep disruption, and cognitive symptoms, including who you told and when.
- Work and daily-life proof: missed work notes, activity limitations, and family observations that are consistent with medical records.
Leverage Note: This is why we send preservation letters early and demand the right records early. When video is gone and the car is repaired, the defense gets more room to argue “minor impact, minor injury.”

Louisiana Law Snapshot (Updated 2026)
Most negligence-based injury claims in Louisiana are subject to a prescriptive period that is time-sensitive and incident-date driven. For many delictual actions arising from incidents on or after July 1, 2024, Louisiana generally provides a two-year prescriptive period under La. Civ. Code art. 3493.1, but earlier incidents may be governed by different deadlines under prior law, so date-math matters.
Fault allocation also matters more than most people realize. Under La. Civ. Code art. 2323, Louisiana uses comparative fault, and for cases governed by the post–January 1, 2026 modification, a claimant who is 51% or more at fault can be barred from recovery, which makes early liability proof and evidence preservation even more important.
