Quick answer: Yes — you should see a doctor after a car accident even if you feel fine. Adrenaline can mask pain, and common injuries such as whiplash, concussion and back injuries often show symptoms 24 to 72 hours later. Getting checked within 72 hours protects your health and creates the medical record your insurance or injury claim depends on. In Florida, you must get initial treatment within 14 days to use Personal Injury Protection (PIP) benefits.
Right after a crash, most people say the same thing: “I’m okay.” Then, a day or two later, the neck stiffens, a headache won’t quit, or the lower back starts to burn. That gap is normal — and it is exactly why insurers look closely at how quickly you sought care. Here is what to watch for and what to do.
Key Takeaways
- Feeling fine after a crash does not mean you are uninjured.
- Many injuries appear 24–72 hours after the accident.
- See a doctor promptly — ideally within 72 hours.
- Florida PIP: initial treatment must happen within 14 days of the accident.
- Delayed treatment is often used by insurers to argue your injury is minor or unrelated.
Why Car Accident Injuries Show Up Late
During a collision your body releases adrenaline and other stress hormones that temporarily block pain. Soft-tissue injuries also take time to swell and stiffen. Even low-speed crashes can create enough force to injure the neck, spine and brain.
Delayed Symptoms You Should Never Ignore
| Symptom | Possible injury | When it often appears |
|---|---|---|
| Neck pain or stiffness, reduced range of motion | Whiplash / soft-tissue injury | Next morning to 72 hours |
| Headaches, confusion, memory problems, light sensitivity | Concussion or traumatic brain injury | Hours to days |
| Lower or mid-back pain that worsens | Herniated disc, sprain or strain | Days |
| Numbness, tingling or weakness in arms or legs | Nerve or spinal injury | Hours to days |
| Abdominal pain, dizziness, deep bruising | Internal injury — seek emergency care | Hours |
| Anxiety, trouble sleeping, flashbacks | Emotional trauma / post-accident stress | Days to weeks |
Go to the emergency room right away for loss of consciousness, severe headache, chest pain, trouble breathing, abdominal pain, or weakness on one side of the body.
What to Do After a Car Accident: Medical Checklist

- See a doctor within 72 hours, even if you feel fine.

- Notify your insurer promptly and ask about PIP or medical payments coverage.
Car Accident Injury Rules in States We Serve
Insurance rules differ by state. Florida and Michigan are no-fault states, where your own Personal Injury Protection coverage pays first — and Florida requires treatment within 14 days to use PIP. In at-fault states such as Texas, Louisiana and Illinois, the at-fault driver’s insurance is usually responsible, but prompt medical documentation is just as important.
Hurt in a Crash While Working?
If the accident happened while you were driving for work — deliveries, sales calls, a company vehicle — it may also be a workers’ compensation claim. Report it to your employer right away and read our guide on what to do after a work injury.

Neck pain and stiffness, reduced range of motion, headaches starting at the base of the skull, shoulder pain, and tingling in the arms are common whiplash signs.
