When you’re involved in an auto accident, the immediate shock can make it hard to understand the extent of the physical and emotional impacts. Injuries from car accidents – whether minor fender-benders or severe collisions – range from whiplash to potentially life-altering conditions like traumatic brain injury and spinal damage.
In this article, we’ll detail the most common injuries people experience in motor vehicle accidents, explain which symptoms can be delayed and emphasize the importance of getting prompt medical care to protect your long-term health.
Whiplash is the most common of all auto accident injuries. It occurs when your body and neck move backward (or forward) while your head moves backward (or forward) and then back in the opposite direction, as in a car accident. It’s a soft-tissue injury that strains the neck muscles and causes symptoms, such as:
Whiplash is the most common injury resulting from a rear-end collision. It can affect the driver and passengers of the vehicle that is hit and can happen even if someone is wearing a seatbelt.
In addition to whiplash, car accidents can cause many injuries that affect your bones, joints, muscles, ligaments and tendons, including:
Symptoms of bone and joint injuries may vary depending on where you were hurt. Often, they cause full-body aches, while other injuries cause pain in specific muscles and joints. You may also experience referred pain, which is pain in areas that seem unrelated to the injured region.
You can develop a traumatic brain injury (TBI) anytime your head experiences a strong bump, blow or jolt, such as when the head comes into contact with the steering wheel or dashboard. These forces cause the brain to move around inside the skull, potentially damaging it.
One TBI commonly caused by auto accidents is a diffuse axonal injury (DAI), which damages your brain’s white matter. White matter contains nerve fibers called axons, which carry nerve signals. DAI damages these fibers and interferes with brain signaling. It can also cause the brain to release harmful chemicals.
Auto accidents can also cause concussions, which are considered mild TBIs. They happen when a blow to the head causes rapid brain movement.
Other TBIs related to car accidents include:
TBIs can affect how you feel, think and act. Symptoms can range from headaches and blurry vision to confusion, mood changes and drowsiness. TBI symptoms can also be delayed, appearing hours or days after the accident.
During a car accident, glass shatters, chemicals can splatter, and car parts can break free. You could experience facial disfigurement. Even the airbag that may be saving you from more serious injury or death can hurt you.
Cuts (medically known as lacerations) and bruises (medically known as contusions) are common in car accidents. They can be mild or severe and affect your entire body, including your face.
You can also cut and bruise internal organs. While external cuts are likely easy to see, internal bleeding is not, and it doesn’t always cause symptoms. When it does, symptoms include:
Whether whiplash, a back sprain or even a concussion, many car accident injuries share one common characteristic: Their symptoms don’t always appear immediately. Symptoms can be delayed and may not appear for hours or even days after an accident.
The reasons for this are varied, but in some cases, it is related to adrenaline, a hormone your body produces in response to stress or perceived danger. Adrenaline masks pain so you can focus on the immediate threat, but the effect is usually temporary. After a few hours or days, you will likely feel the pain caused by the accident. You may think you feel a bit sore merely because of the ordeal that your body experienced, but your pain could be a symptom of a much more serious problem.
That’s why it’s so important to seek care as soon as possible after an accident. Your injuries may be visible, but even if they are not, seeing a doctor allows you to receive care quickly before complications develop.
Car accidents, both minor and severe, can cause a wide range of injuries, from whiplash and other types of muscle strains to traumatic brain injuries, spinal damage and broken bones. The type of collision – whether it’s a rear-end, side-impact, front impact or a single-car accident – often dictates the most likely injuries, but every accident carries a risk of lasting physical and mental repercussions.
Given that many symptoms can be delayed, sometimes for hours or even days, the most crucial step following any motor vehicle accident is to get care quickly. Early diagnosis and treatment can address serious injuries you may not know you have and prevent potential complications that could negatively impact your long-term health and well-being.
