Persistent Swelling After Car Accident: When to Seek Medical Advice

The wound from the car accident has healed, but there is still swelling?

Today, during a car accident in February, I may have been startled and briefly lost consciousness.
When I was called back, my leg was pinned under a motorcycle, and it took a moment to move.
Fortunately, I was wearing long pants, and I only had a small abrasion on the inner side of my calf, which has healed.
However, I still feel warmth and slight swelling in that area, and I can notice a difference in the size of my legs.
Later, my teacher suggested I see an infectious disease specialist, who recommended a course of antibiotics, which I completed.
After finishing the medication in April, I felt somewhat better; the warmth and swelling decreased, but I can still feel some swelling when I touch it.
Generally, it doesn't affect my daily life, but recently, during my internship, I have to stand for long periods, and by the end of the day, my foot feels particularly swollen and puffy.
Elevating my leg provides some relief.
Is this normal? Will it heal on its own, or do I need to see a doctor again? Thank you.

Hello! It is recommended to directly perform a CT scan of the lower leg, as chronic deep tissue infection needs to be considered.

More Info

After a car accident, persistent swelling and discomfort in the affected area can be concerning and warrants careful consideration. Based on your description, it seems that you experienced a significant trauma to your leg, which has resulted in ongoing swelling and a sensation of heat in the area. While it is positive that you do not have any open wounds or severe pain, the fact that you still feel swelling and discomfort, especially after prolonged standing, suggests that further evaluation may be necessary.

In the context of a car accident, injuries can range from minor soft tissue damage to more serious conditions such as fractures or internal injuries that may not be immediately apparent. The swelling you are experiencing could be due to several factors, including:
1. Soft Tissue Injury: Even if there are no visible signs of injury, soft tissue injuries such as sprains, strains, or contusions can lead to swelling and discomfort. These injuries may take time to heal and can sometimes result in lingering symptoms.

2. Post-Traumatic Edema: After an injury, it is common for the body to respond with inflammation, leading to swelling. This is part of the healing process, but if the swelling persists for an extended period, it may require further investigation.

3. Compartment Syndrome: Although less common, if the swelling is significant and accompanied by severe pain, numbness, or a feeling of tightness in the leg, it could indicate compartment syndrome, a serious condition that requires immediate medical attention.

4. Infection: While you mentioned that you were treated with antibiotics, it is essential to monitor for any signs of infection, such as increased redness, warmth, or discharge from the area. If these symptoms arise, you should seek medical attention promptly.

5. Venous Insufficiency: Prolonged standing can exacerbate swelling, particularly if there is an underlying issue with venous return in your legs. This can lead to discomfort and a feeling of heaviness in the legs.

Given that you have already seen a doctor and were prescribed antibiotics, it is crucial to follow up if your symptoms do not improve or if they worsen. Here are some recommendations for managing your symptoms and determining when to seek further medical advice:
- Rest and Elevation: When possible, elevate your leg to help reduce swelling. This can be particularly beneficial after long periods of standing.

- Compression: Consider using compression stockings or wraps to help manage swelling and improve circulation in your legs.

- Monitor Symptoms: Keep track of any changes in your symptoms. If you notice increased swelling, pain, or any new symptoms, it is essential to consult a healthcare professional.

- Follow-Up with a Specialist: If your symptoms persist despite conservative measures, it may be beneficial to see a specialist, such as an orthopedic surgeon or a vascular specialist, for a more thorough evaluation.

In summary, while some swelling and discomfort can be expected after an injury, persistent symptoms that do not improve warrant further investigation. It is always better to err on the side of caution when it comes to your health, so if you have any doubts or concerns, do not hesitate to seek medical advice. Your well-being is the priority, and a healthcare professional can provide the necessary guidance and treatment options tailored to your situation.
