What to do about bruises and swelling after a car accident?


Hello Doctor: I had a car accident 20 days ago, and I developed a large bruise on the inner thigh.
The bruise has decreased in size, but now there is a noticeable hard lump measuring 3x4 cm.
What should I do to make the lump disappear? Should I consider massage, injections, or surgery for it to completely resolve? Thank you.

Hello: It is recommended that you visit the trauma or plastic surgery outpatient clinic for treatment.
If it is a bruise with a hematoma, it is advised to use alternating hot and cold compresses, with hot compresses at approximately 40 degrees Celsius for 10-15 minutes, followed by cold compresses at about 10 degrees Celsius for 10-15 minutes.
Starting with hot compresses and ending with hot compresses may help the bruise resolve more quickly.
Thank you.

More Info


After a car accident, the appearance of a hard lump following a bruise can be concerning. This lump is often a result of hematoma formation, which occurs when blood collects outside of blood vessels due to trauma. In your case, the hard lump on your inner thigh, which developed after the bruise, is likely a localized collection of blood that has clotted and formed a solid mass.

Understanding the Condition
When you experience a bruise, the blood vessels under the skin break, leading to bleeding in the surrounding tissues. Initially, this results in discoloration and swelling. As the body begins to heal, the blood may pool and form a hematoma, which can feel firm or hard to the touch. Over time, the body will reabsorb this blood, and the lump may gradually decrease in size.


Treatment Options
1. Observation: In many cases, if the lump is not causing significant pain or discomfort, it may be best to simply monitor it. The body often resolves these hematomas naturally over time, and they can take weeks to months to fully disappear.

2. Rest and Ice: Initially, applying ice to the area can help reduce swelling and alleviate pain. Make sure to wrap ice in a cloth to avoid direct contact with the skin, which can cause frostbite. Resting the affected area is also crucial to allow healing.

3. Compression: Using a compression bandage can help manage swelling and provide support to the area. However, be cautious not to wrap it too tightly, as this can impede circulation.

4. Elevation: Keeping the affected leg elevated can help reduce swelling by allowing fluids to drain away from the injury site.

5. Pain Management: Over-the-counter pain relievers such as ibuprofen or acetaminophen can help manage any discomfort associated with the lump.

6. Physical Therapy: If the lump persists or if there is associated stiffness or decreased range of motion, consulting a physical therapist may be beneficial. They can provide targeted exercises to improve mobility and reduce discomfort.

7. Medical Evaluation: If the lump does not decrease in size over several weeks, becomes increasingly painful, or shows signs of infection (such as redness, warmth, or discharge), it is essential to seek medical attention. A healthcare provider may perform imaging studies, such as an ultrasound, to assess the lump and determine if further intervention is necessary.

8. Injections or Surgery: In some cases, if the hematoma is large and symptomatic, a doctor may recommend a corticosteroid injection to reduce inflammation or, in rare cases, surgical intervention to drain the hematoma.


Conclusion
In summary, the hard lump you are experiencing after your car accident is likely a hematoma that will gradually resolve on its own. It is essential to monitor the lump and manage any discomfort with rest, ice, and over-the-counter medications. If the lump persists or worsens, seeking medical advice is crucial to rule out any complications. Always consult with a healthcare professional for personalized advice and treatment options tailored to your specific situation.

Dr. Lu Daokuan reply Plastic Surgery
If the blood clot is mostly absorbed, a large clot should have liquefied within a month. A 1 cm hard mass may be a localized fibrotic reaction following an injury, which typically softens gradually over 2 to 3 months.
