Leg Contusions: Recovery Time and When to Seek Help - Surgery

Leg contusion?


I would like to ask the doctor about an incident that occurred two weeks ago when I was hit by a car on my calf.
At that time, there was significant swelling, forming a lump approximately 5 cm in diameter and over 1 cm high, without any open wounds.
There was only a slight bruise and some pain.
An X-ray was taken, and there were no fractures.

1.
How long should it take for this swelling to completely subside? Is it normal for it to still hurt after two weeks? Is there a risk of infection if left untreated, considering there are no open wounds?
2.
What changes should prompt me to return to the hospital immediately? Is surgery necessary to resolve this issue?
Here are images of the swelling: this is the size when it first started swelling https://iiil.io/xkQP and this is the size two weeks later https://iiil.io/kQDY.
Thank you for your assistance, doctor.

The image cannot be read (blocked by antivirus software), but clinically, it is mostly a hematoma.
The resolution time generally depends on the original size; if there is slight reduction after two weeks, there is no need to worry too much, indicating that it is being absorbed slowly.
If there is no trauma, there is not much concern about the risk of suppuration.
However, if there is an infection, signs such as redness, heat, and increased pain will appear.

When it comes to leg contusions, particularly those resulting from trauma such as being hit by a vehicle, understanding the recovery process and knowing when to seek further medical attention is crucial. Based on your description, it seems you experienced a significant contusion to your calf, which has resulted in swelling and pain but no fractures as confirmed by X-ray.

1. Recovery Time: Contusions can vary widely in terms of recovery time depending on the severity of the injury. Generally, mild to moderate contusions may take anywhere from a few days to a couple of weeks to heal, while more severe cases can take several weeks to months. Since you mentioned that it has been two weeks and you are still experiencing pain, this can be considered normal, especially if the swelling has decreased but is still present. Pain can linger as the body continues to heal, and it is not uncommon for some discomfort to persist for several weeks after the initial injury.
2. Potential Complications: In terms of complications, the risk of infection (such as abscess formation) is generally low in cases of contusions without open wounds. However, if you notice any signs of infection such as increased redness, warmth, swelling, or discharge, or if you develop a fever, it would be important to seek medical attention promptly. Additionally, if the pain worsens or if you experience new symptoms such as numbness, tingling, or inability to move your leg, these could be signs of a more serious issue that requires immediate evaluation.

3. When to Seek Help: You should consider returning to the hospital or consulting with your healthcare provider if:
- The swelling does not begin to decrease after two weeks.

- The pain becomes more severe or does not improve with rest and over-the-counter pain relief.

- You experience any new symptoms, such as changes in skin color, warmth, or signs of infection.

- You have difficulty walking or bearing weight on the affected leg.

4. Surgical Intervention: Surgical intervention is not typically required for contusions unless there are complications such as compartment syndrome, which is a serious condition that occurs when pressure within the muscles builds to dangerous levels. This can lead to muscle and nerve damage. Signs of compartment syndrome include severe pain that does not improve with rest, a feeling of tightness in the muscle, and decreased sensation or movement in the affected area. If you have any concerns about these symptoms, it is critical to seek immediate medical attention.

In summary, while it is normal for pain and swelling to persist for a couple of weeks following a leg contusion, it is essential to monitor your symptoms closely. If you notice any concerning changes or if the pain does not improve, do not hesitate to reach out to your healthcare provider for further evaluation. Rest, ice, compression, and elevation (RICE) are typically recommended for managing contusions, along with over-the-counter pain relief as needed.

If you can walk, there's no need to worry, because even a slight hairline fracture would cause enough pain to prevent walking. If it's just a bruise, it should gradually stop hurting in about two weeks.
