Crash injuries hide. The same adrenaline that gets you through the scene masks the symptoms that put people in treatment weeks later.
Prompt, well-documented treatment protects both your health and your claim.
The 72-hour rule
Get a medical evaluation within 72 hours of any collision — ER for serious symptoms, urgent care or your physician otherwise. Two reasons:
Health: concussions, internal bleeding, and spinal injuries can be asymptomatic at first and dangerous untreated.
Documentation: insurers treat any gap between crash and treatment as evidence you weren't really hurt. Prompt records connect the injury to the crash.
Injuries that show up late
Whiplash / soft-tissue injuries — neck and shoulder pain often peaks 24–72 hours after impact.
Concussion / mild TBI — headaches, fog, irritability, light sensitivity, sleep changes. Can appear days later.
Back injuries — herniated or bulging discs may start as mild stiffness.
Internal injuries — abdominal pain, dizziness, or deep bruising after seatbelt loading needs immediate attention.
PTSD and driving anxiety — real, common, and treatable; document it like any other symptom.
Red flags — go to the ER now: loss of consciousness, worsening headache, repeated vomiting, numbness or tingling, abdominal pain or swelling, confusion, or slurred speech.
Building your treatment record
Tell every provider it was a car accident, and report every symptom — minor ones included.
Follow the treatment plan. Skipped appointments become "evidence" you recovered.
Keep copies of every record, bill, prescription, and imaging report.
Keep a daily symptom journal: pain levels, sleep, missed work, activities you couldn't do.
Who pays for treatment?
It varies by state. In no-fault / PIP states, your own policy's Personal Injury Protection pays first regardless of fault. In at-fault states, your health insurance or med-pay coverage typically pays now, and the at-fault driver's insurer reimburses at settlement. Never delay treatment while fault is sorted out — that's what liens and letters of protection exist for, and an attorney can arrange them. More on legal help →
Frequently asked questions
Should I go to the ER even if I feel fine?
If the crash was significant — airbag deployment, vehicle towed, any loss of consciousness — yes. Otherwise see urgent care or your doctor within 72 hours. Feeling fine immediately after a crash is common and unreliable.
What is whiplash and how long does it last?
Whiplash is a neck soft-tissue injury from rapid back-and-forth head motion. Most cases resolve in weeks with treatment, but untreated cases can become chronic. Symptoms often peak 1–3 days after the crash.
Will my health insurance cover accident injuries?
Generally yes, subject to your normal deductibles, and your insurer may later seek reimbursement (subrogation) from any settlement. In PIP states, your auto policy pays first.
Why does a gap in treatment hurt my claim?
Adjusters argue that anyone genuinely injured would have sought care promptly, so a gap between the crash and your first visit — or missed follow-ups — is used to dispute that the crash caused your injuries.
