Burns with blisters?

Dear Doctor: Last night I suffered a burn on my foot that resulted in a blister approximately 3 cm wide and 1 cm high.
I drained the fluid from the blister, but the epidermis remained intact.
After that, I applied an anti-inflammatory ointment.
However, after a night, the blister has filled up again.
Is this a normal occurrence? Do I need to take any special measures? Thank you!

Hello: In response to your question, it is normal for there to be serous fluid drainage under the blister before the epidermis has healed.
If you choose to drain it yourself, be careful to avoid infecting the wound, or you can simply keep the blister intact and allow it to heal and be absorbed naturally.

More Info

Burns can lead to the formation of blisters, which are fluid-filled sacs that develop as a protective response of the skin to injury. When the skin is burned, the body reacts by creating these blisters to help protect the underlying tissues from further damage and to facilitate healing. Understanding the nature of blisters after burns is crucial for proper care and recovery.

In your case, the blister that formed after your burn is a common occurrence. The blister itself is a sign that your body is responding to the injury. When you drained the blister, you may have inadvertently disrupted the natural healing process. The fluid inside a blister serves several purposes: it cushions the damaged area, provides a moist environment that promotes healing, and contains proteins and nutrients that aid in tissue repair.

After draining a blister, it is not unusual for it to refill with fluid. This can happen as the body continues to respond to the injury. The fact that the blister's surface remains intact is a positive sign, as it indicates that the skin is still providing some level of protection to the underlying tissues. However, it is essential to monitor the blister for any signs of infection, such as increased redness, swelling, warmth, or pus.

Here are some recommendations for managing blisters after burns:
1. Do Not Drain Blisters Unless Necessary: If a blister is large and painful, draining it may be necessary, but it should be done with caution. If you choose to drain it, ensure that you use a sterile needle and clean the area thoroughly before and after the procedure.
2. Keep the Area Clean: Gently wash the area with mild soap and water. Avoid using harsh chemicals or scrubbing the blister, as this can cause further irritation.

3. Apply a Protective Dressing: After cleaning, cover the blister with a sterile, non-stick dressing. This will help protect it from infection and further injury. If the blister has been drained, consider using a hydrocolloid dressing, which can provide a moist environment conducive to healing.

4. Avoid Irritation: Try to keep the area free from friction and pressure. Wearing loose-fitting shoes can help prevent additional trauma to the blistered area.

5. Monitor for Infection: Keep an eye on the blister for any signs of infection. If you notice increased redness, swelling, or pus, or if you develop a fever, seek medical attention promptly.

6. Pain Management: If you experience pain, over-the-counter pain relievers such as acetaminophen or ibuprofen can help alleviate discomfort.

7. Consult a Healthcare Professional: If you have concerns about the blister or if it continues to refill with fluid, it is advisable to consult a healthcare professional. They can assess the burn's severity and provide appropriate treatment recommendations.

In summary, the refilling of the blister after drainage is a normal response as your body continues to heal. Proper care, including keeping the area clean and protected, is essential for recovery. If you have any doubts or if the condition worsens, do not hesitate to seek medical advice. Remember, burns can vary in severity, and professional evaluation is always a good idea for optimal healing.
