Low-Temperature Burns: Symptoms and Treatment Insights - Dermatology

More Info

---

Low-temperature burns, often referred to as "frostbite" or "cold burns," can occur when the skin is exposed to cold surfaces or materials for an extended period. In your case, it seems that the burn resulted from a heating pad, which is somewhat atypical, as heating pads are generally used to provide warmth rather than cold exposure. However, burns can occur if the heating pad is too hot or if it is left in contact with the skin for too long, leading to skin damage.

The symptoms you describe—redness, swelling, and the formation of blisters—are typical responses to burns. When the skin is burned, the body reacts with inflammation, which can cause redness and swelling as blood flow increases to the affected area. The formation of blisters is a protective mechanism; they serve to cushion the underlying tissue and provide a barrier against infection.

The fact that the area has changed from multiple smaller blisters to one large blister is not uncommon. Blisters can merge as the skin continues to react to the injury. However, the persistent swelling and the sensation of the skin feeling "like a water balloon" are concerning. This could indicate that the burn is more severe than initially thought, and the accumulation of fluid under the skin (edema) may be significant.

Here are some insights into the management of low-temperature burns:
1. Initial Care: For any burn, the first step is to cool the area to stop the burning process. This is typically done with cool (not cold) water for 10-20 minutes. However, since the injury has already occurred, the focus should be on managing the symptoms.

2. Medication: The anti-inflammatory and pain-relieving medications prescribed by the dermatologist are appropriate. These can help reduce pain and swelling. It's essential to follow the prescribed dosage and frequency.

3. Blister Management: If the blisters are intact, it is generally advised to leave them alone. They provide a natural barrier against infection. If they burst, keep the area clean and covered with a sterile bandage. If the blister is large and painful, a healthcare provider may need to drain it to relieve pressure, but this should be done in a sterile environment to prevent infection.

4. Monitoring for Infection: Watch for signs of infection, such as increased redness, warmth, swelling, or pus. If any of these symptoms occur, or if the pain worsens, seek medical attention promptly.

5. Follow-Up Care: Since the swelling persists and walking is difficult, it may be wise to follow up with your healthcare provider. They can assess the burn's severity and determine if further treatment is necessary, such as physical therapy or more advanced wound care.

6. Hydration and Nutrition: Ensure that your family member stays well-hydrated and consumes a balanced diet to support healing.

In summary, while some changes in the appearance of the burn may be normal, the degree of swelling and discomfort you describe warrants further evaluation by a healthcare professional. It is crucial to ensure that the burn is healing properly and to prevent any complications, such as infection or prolonged discomfort.
