Burn Injury After Three Weeks: Sudden Redness, Swelling, and Pain - Surgery

Share to:

The burn has been present for about three weeks, and suddenly there is redness, swelling, itching, and pain?


I initially burned the left half of my left foot with boiling water.
I immediately rinsed it with water and have been receiving continuous medical treatment.
However, blisters developed over two weeks, and they did not all appear at once; they formed gradually.
Now, in the third week approaching the fourth week, the surface of my left foot is still continuously exuding serous fluid.
Especially today, halfway through work, I suddenly experienced intense itching and stabbing pain.
When I got home and removed the bandage, I found that 80% of the originally white area of the wound had turned red, and there were many raised white bumps on the surface.
Could this mean that my foot is having an allergic reaction? I can't seek medical attention on weekends, but the itching is unbearable...

Hello! Continue to change the burn ointment 2 to 3 times a day, and avoid contact with tap water.
This will take some time.
You mentioned that 80% of the originally white area of the wound on your foot has turned red.
Without seeing it in person, I cannot make a judgment.
If it itches, you can take antihistamines.
Take care! Changhua Hospital is concerned about you!

It sounds like you are experiencing a complex healing process following a burn injury. Based on your description, it seems that you sustained a significant burn, possibly a second-degree burn, which can take several weeks to heal properly. The symptoms you are experiencing—persistent oozing, sudden redness, swelling, and intense itching—are concerning and warrant careful consideration.

Firstly, the fact that your burn has been oozing for three weeks is not typical for a healing burn. While some oozing can occur, especially in the initial stages of healing, prolonged drainage may indicate an infection or other complications. The sudden onset of intense itching and the appearance of red areas could suggest a few possibilities:
1. Infection: The presence of redness, swelling, and increased pain or itching can be signs of an infection. Infections can occur in burn wounds due to the breakdown of the skin barrier, allowing bacteria to enter. If you notice any pus, increased warmth around the area, or fever, it is crucial to seek medical attention immediately.

2. Allergic Reaction: The itching and redness could also indicate an allergic reaction to the dressing materials or topical medications you are using. Some individuals may develop sensitivities to certain types of bandages or ointments, leading to contact dermatitis. If you suspect this, it might be helpful to discuss alternative dressings or medications with your healthcare provider.

3. Normal Healing Process: While it is less likely given the duration and severity of your symptoms, it is also possible that the changes you are observing are part of the normal healing process. Burns can undergo various stages of healing, and the appearance of white bumps could be related to the formation of new tissue or the shedding of dead skin. However, this should be monitored closely.

Given that you are experiencing significant discomfort and changes in your burn wound, it is essential to consult a healthcare professional as soon as possible. If you cannot see a doctor immediately, consider reaching out to a telehealth service for guidance. In the meantime, here are some general care tips for burn injuries:
- Keep the Area Clean: Gently clean the burn area with mild soap and water. Avoid scrubbing the wound, as this can cause further irritation.

- Avoid Irritants: If you suspect an allergic reaction, try to avoid any products that may have come into contact with the burn area, including certain ointments or dressings.

- Moisturize: If the area is dry, applying a gentle, fragrance-free moisturizer may help soothe the skin. However, avoid applying anything directly to the wound without medical advice.

- Pain Management: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help manage pain and inflammation. Always follow the recommended dosage instructions.

- Monitor for Changes: Keep an eye on the wound for any signs of worsening, such as increased redness, swelling, or discharge. If you notice these symptoms, seek medical attention promptly.

In conclusion, while some changes in your burn wound may be part of the healing process, the prolonged oozing, sudden redness, and intense itching are concerning. It is crucial to seek medical advice as soon as possible to ensure proper treatment and to rule out any complications. Your health and recovery are the top priority, so do not hesitate to reach out for help.
