Your body experiences many changes for hours, days, and even weeks after a car accident. These physical changes may produce symptoms that affect you physically, mentally, and emotionally.
If another driver’s negligence caused the crash, you may be entitled to seek compensation for injuries and symptoms related to the accident. This compensation can cover medical care and income losses resulting from the injuries.
Physical Changes After a Car Accident
The trauma from a car collision can cause immediate injuries. For example, the impact of your face on the airbag might break your nose. You would experience the effects of this injury immediately, as your nose bleeds and you feel intense facial pain. However, trauma can also have other effects that take time to develop.
Delayed Pain
The shock of a car accident causes a rush of endorphins and adrenaline in your brain. These hormones are designed to prepare your body for the fight-or-flight response. One effect on your body is the suppression of pain sensations. As the adrenaline and endorphins wear off in the hours after the accident, you will experience the pain your body previously suppressed.
Pain is your body’s way of communicating that tissues have been damaged. As the delayed pain arises after an accident, you might realize that you were more injured than you thought.
Inflammation
Inflammation is the body’s response to injury. The injured body part swells to trap any dangerous microorganisms from spreading through the body. It also increases in temperature to kill the invading germs.
Inflammation takes time to develop. After a car accident, you may experience worsening swelling for hours or even days.
For example, one cause of concussion symptoms is swollen brain tissue. After your brain is jolted in a car accident, it may take hours or days for the damaged brain cells to swell. During this time, you may experience symptoms like headaches, confusion, and difficulty concentrating.
Clotting
After an injury, your body produces clotting factors to prevent blood loss. Clotting can save your life if you have a laceration. However, it can also have negative effects.
For example, suppose you broke your leg in a crash. In the hours after the crash, your body will build a blood clot over the fracture to start the healing process. In some cases, serious injuries may increase the risk of dangerous blood clots, making prompt medical evaluation especially important.
Post-Traumatic Stress Disorder
Although Post-traumatic stress disorder (PTSD) is a mental health condition, it can also cause physical symptoms.PTSD is a natural response to a traumatic event. The brain attempts to protect itself from future trauma by turning up its sensitivity to triggers that remind it of the event.
As a result, you might experience anxiety, insomnia, nightmares, and flashbacks. However, this psychological condition can also affect physical health. The physical effects might include profuse sweating, rapid heart rate, high blood pressure, and muscle tension.
Why Prompt Medical Care Matters After a Car Accident
Even if you feel fine immediately after a crash, you should seek medical attention as soon as possible. A healthcare provider can identify injuries that may not be obvious right away and recommend appropriate treatment before the condition worsens.
Prompt medical care also creates records that connect your injuries to the accident. These medical records often become important evidence if you later file an insurance claim or personal injury lawsuit.
