Injuries after a car accident?

Hello Doctor: I was in a minor car accident on April 7th, and I have a wound on my left calf (approximately 2 cm long and 1 cm wide).
The area around the wound is bruised, and the wound is slowly scabbing over.
The bruised area is still painful when lightly pressed, but a small portion of skin above the wound (about 3 cm x 5 cm) has lost sensation.
In other words, I cannot feel anything when I touch that area, but I can feel pain from the deeper tissues when pressure is applied.
I would like to ask, is this normal? Will the sensation return on its own? Thank you!

Hello: Based on the situation you described, the wound on your left leg is likely a combination of abrasion and contusion.
The severity of the contusion can vary; in severe cases, it can lead to hematoma, fat necrosis, or even deep muscle and tendon injuries.
Additionally, the superficial nerves may also be affected, resulting in localized sensory abnormalities.
Whether recovery is possible depends on the extent of the nerve injury, which is not easily determined by appearance alone.
The most accurate assessment would require microscopic examination of the nerve condition (though this is often impractical), but generally, it correlates with the overall severity of the surrounding tissue contusion.

I would also like to remind you that while contusions may appear less severe than fractures or lacerations, the associated internal injuries are often overlooked, potentially leading to missed opportunities for optimal treatment or rehabilitation, resulting in long-term or permanent functional impairments.
Therefore, I recommend that if your injury is healing more slowly than expected, it is advisable to seek medical attention promptly.

More Info

After a minor car accident, experiencing loss of sensation in a specific area of the skin, particularly around an injury, can be concerning. Based on your description, it seems that you have a small wound on your left calf, accompanied by bruising and a loss of sensation in a localized area above the wound. This situation can be attributed to several factors related to the injury.

Firstly, the loss of sensation you are experiencing could be due to nerve damage or irritation caused by the trauma from the accident. When the skin and underlying tissues are injured, the nerves that supply sensation to that area can also be affected. This can lead to a condition known as neuropraxia, where the nerve is temporarily damaged but not severed. In such cases, the nerve may still be intact, but its ability to transmit sensory signals is impaired. This could explain why you can feel pressure (which is transmitted through deeper tissues) but not light touch.

The healing process for nerve injuries can vary significantly. In many cases, if the nerve is only mildly damaged, sensation may gradually return over time as the nerve heals. This process can take weeks to months, depending on the severity of the injury. However, if the nerve has been significantly damaged, recovery may be incomplete, and some degree of sensation loss could persist.

It is also important to consider the surrounding soft tissue injury. Bruising and swelling can contribute to localized pain and altered sensation. As the bruising resolves and the swelling decreases, you may notice an improvement in sensation as well.

While some degree of sensation loss can be normal following such an injury, it is crucial to monitor your symptoms closely. If you notice that the area remains numb or if the sensation does not improve over the next few weeks, it would be advisable to seek medical attention. A healthcare professional may recommend imaging studies or nerve conduction studies to assess the extent of any nerve damage and to rule out other potential complications.

In summary, while it is not uncommon to experience loss of sensation after a minor car accident, the extent and duration of this loss can vary. Many individuals do recover sensation over time, but it is essential to keep an eye on your symptoms and consult with a healthcare provider if you have concerns about your recovery. Early intervention can be beneficial in ensuring proper healing and addressing any underlying issues that may arise from the injury.
