A car accident can happen in seconds. Even a minor crash can leave you with injuries that may take hours or days to appear. You might feel fine right after the accident, only to wake up the next morning with neck pain or a headache.

Knowing what to watch for can help you get the care you need.

Why injuries may take time to appear

During a crash, your body can move forward and backward very quickly. This sudden movement can strain your muscles and joints.

Right after an accident, your body releases stress hormones, including adrenaline. These hormones can make it harder to notice pain.

As the hours pass, you may begin to feel sore or stiff. Some injuries, such as a concussion, may also cause symptoms that appear later.

Common injuries after a car accident

Whiplash

Whiplash happens when your head moves back and forth suddenly. It can strain the muscles and other tissues in your neck.

You may notice neck pain, stiffness, or trouble turning your head. Headaches can also occur.

Back pain

A crash can strain the muscles and joints in your back. You may feel pain when bending, sitting, or standing.

Pain that travels down your leg, along with tingling or numbness, may be a sign of nerve irritation.

Head injuries

You can suffer a concussion even if you do not hit your head. The sudden movement of your brain inside your skull can cause an injury.

Watch for headaches, dizziness, confusion, or trouble focusing.

Warning signs you should never ignore

Some symptoms need emergency medical care.

Call 911 if you experience:

A severe or worsening headache

Repeated vomiting or increasing confusion

Weakness or numbness in your arms or legs

Trouble breathing or severe chest pain

Severe neck or back pain, especially with weakness

Loss of consciousness or seizures

These symptoms may point to a serious injury.

What should you do after a minor crash?

First, make sure you are safe. Move away from traffic if you can do so safely.

Next, pay attention to how your body feels. If you have pain or other symptoms, seek a medical evaluation. Even if you feel fine, consider contacting a healthcare professional after a crash, especially if you hit your head.

Avoid heavy lifting or hard exercise if you are injured. Gentle movement may help some muscle strains, but follow your healthcare provider's advice.

Keep track of any new symptoms. Write down when they started and what makes them worse.

Dr. Acanfora's Takeaway

• The amount of damage to your car does not always tell you how badly you may be hurt. A minor crash can still cause an injury.

• Pay attention to changes in how you feel. Getting checked when symptoms appear can help you understand your injury and choose the right care.
