Dealing with Swollen Wounds: Should You Drain or Leave It Alone? - Surgery

Wound impact?


Hello, doctor.
I had a knee injury from a car accident, and the wound had scabbed over and seemed to have healed.
However, yesterday I accidentally bumped it, and although the impact wasn't very strong, it has swollen up, and I feel like there is blood inside.
Should I try to break it open to let the blood out, or can I just leave it alone?

Hello! You should visit the clinic or surgical outpatient department again! If you need to break it, you must have sterile preparation.
Avoid touching tap water for now, and quickly see a surgeon! Changhua Hospital cares about you!

When dealing with a swollen wound, especially one that has previously healed and is now swollen again due to trauma, it is essential to approach the situation with caution. Here’s a comprehensive guide on how to handle this issue.


Understanding the Situation
From your description, it seems that you have a history of a knee injury that has healed but has now become swollen after a minor impact. This swelling could be due to several reasons, including:
1. Fluid Accumulation: After an injury, the body may produce excess fluid in the area, leading to swelling.

2. Bruising: The impact could have caused bruising, which can lead to localized swelling.

3. Infection: If the wound was not entirely healed or if bacteria entered the area, it could lead to an infection, resulting in swelling, redness, and possibly pus.

4. Hematoma: If there was bleeding under the skin, a hematoma could form, causing swelling.


Should You Drain It or Leave It Alone?
1. Do Not Drain It Yourself: It is generally not advisable to drain a swollen area on your own. Attempting to puncture or drain a wound can introduce bacteria, leading to infection. Moreover, if the swelling is due to a hematoma or fluid accumulation, improper drainage can worsen the situation.

2. Monitor Symptoms: Keep an eye on the wound for any signs of infection, such as increased redness, warmth, pus, or fever. If you notice any of these symptoms, it is crucial to seek medical attention.

3. Rest and Elevation: Resting the affected area and elevating your leg can help reduce swelling. Avoid putting weight on the injured knee until the swelling subsides.

4. Ice Application: Applying ice wrapped in a cloth to the swollen area for 15-20 minutes every hour can help reduce swelling and alleviate pain. Make sure not to apply ice directly to the skin to avoid frostbite.

5. Pain Management: Over-the-counter pain relievers like ibuprofen or acetaminophen can help manage pain and reduce inflammation. However, always follow the recommended dosage and consult with a healthcare provider if you have any underlying health conditions.


When to Seek Medical Attention
If the swelling does not improve within a few days, or if you experience increasing pain, redness, or warmth in the area, it is essential to consult a healthcare professional. They may perform an examination and possibly imaging studies (like an X-ray) to determine if there is a more serious underlying issue, such as a fracture or significant internal bleeding.


Conclusion
In summary, do not attempt to drain the swollen area yourself. Instead, focus on rest, ice application, and monitoring for signs of infection. If symptoms persist or worsen, seek medical attention promptly. Remember, your health and safety are paramount, and professional guidance is crucial in managing injuries effectively.
