If you have any pain, dizziness, headache, or you hit your head, get checked at an ER the same day as your crash. If you feel completely fine, you are not out of the woods yet. Some injuries take time to show. The CDC notes that some concussion symptoms may not appear for hours or days after the injury. This guide walks you through the decision: which symptoms mean go now, which delayed signs to watch over the next few days, and when 911 is the only right answer.
Why You Can Feel Fine and Still Be Injured
Feeling fine at the scene does not rule out an injury. MedlinePlus notes that symptoms of a head injury can occur right away or develop slowly over several hours or days.
The head may look fine while bleeding or swelling builds inside the skull, MedlinePlus adds. That is why “I feel fine” is a starting point, not a conclusion.
Go to the ER Now: Symptoms That Cannot Wait
Come in the same day if you notice any of the following after a crash:
- Chest pain or shortness of breath. Our chest pain evaluation includes an EKG and imaging.
- A headache that builds, or any head strike. A blow to the head deserves evaluation before you sleep it off.
- Abdominal pain, swelling, or a seatbelt bruise.
- Numbness, tingling, or weakness in an arm or leg.
- Confusion, unusual drowsiness, or vision changes.
- New neck or back pain that worsens with movement.
Call 911 instead of driving if there is uncontrolled bleeding, a suspected spine injury, loss of consciousness, or someone who cannot safely move.
Delayed Symptoms: What to Watch for in the Days After
Some crash injuries follow their own clock. Watch for these over the next few days:
- Neck stiffness and pain. With whiplash, neck pain often starts a few hours after the crash or the next day, according to a medical review of whiplash injury.
- Headache, fogginess, or mood and sleep changes. MedlinePlus notes concussion symptoms may start days or weeks after the injury. Our concussion treatment page covers the warning signs in depth.
- Growing abdominal pain, swelling, or deep bruising.
- Tingling, numbness, or weakness that spreads.
Anyone on blood thinners, anyone pregnant, and any child involved in a crash should be evaluated the same day even without symptoms. MedlinePlus notes that bleeding in people who take blood-thinning medicine requires medical attention right away.
What the ER Checks After a Crash
A post-accident visit is a systematic search for what adrenaline is hiding. A physician examines your head, neck, spine, chest, and abdomen, then orders the right studies from our on-site imaging suite: CT for the head and internal organs, X-ray for bones, ultrasound for soft tissue and bleeding.
Every finding is documented. That record matters for your recovery plan, and it matters for any insurance claim, because it ties your injuries to the crash with a timestamp. If someone else caused the accident, ask our team about a letter of protection, which lets treatment start while a claim is pending.
911, ER, or Watch at Home?
- Call 911: uncontrolled bleeding, unconsciousness, suspected spine injury, severe chest pain, or anyone trapped or unable to move safely.
- Go to the ER today: any symptom from the lists above, any head strike, or a passenger who is pregnant, a child, or on blood thinners.
- Watch at home: a genuinely minor bump with zero symptoms, in a healthy adult, with someone available to watch for changes. Keep checking yourself over the next few days, and come in the moment anything develops.

FAQs
How long after a car accident can injuries show up?
Some injuries show up hours or days later. With whiplash, neck pain often starts a few hours after the crash or the next day. The CDC notes that some concussion symptoms may not appear for hours or days.
Should I get checked after a minor fender bender?
Get checked if you have any symptom at all, hit your head, are pregnant, take blood thinners, or a child was in the car. A truly symptom-free healthy adult can watch at home over the next few days, but the threshold for coming in should stay low.
Do I need an appointment for a post-accident checkup?
No. ER of Irving is walk-in only, 24 hours a day, every day of the year. An experienced emergency physician examines you, orders imaging on the spot when it is needed, and reviews the results with you during the same visit.
Why does the ER visit matter for my insurance claim?
Because it creates a timestamped medical record connecting your injuries to the crash. Waiting a week weakens your documentation. If another driver caused the accident, ask about a letter of protection so treatment does not wait on the claim.
