Aesthetic Medicine, Dermatology and Bariatric Surgery

Blisters on the skin are common and usually heal on their own with proper care. However, there are certain warning signs and symptoms that may indicate a blister is more serious and requires medical attention. Here’s when you should be concerned and seek professional help.

Warning Signs and Symptoms of Serious Blisters

1. Infection:

Redness and Swelling: If the skin around the blister becomes red, inflamed, and warm to the touch.

Pus: Presence of pus or yellowish fluid indicates a possible infection.

Severe Pain: Pain that increases rather than subsides.

2. Changes in Appearance:

Abnormal Size: Extremely large blisters or those that continue to grow.

3. Other Concerning Symptoms:

Fever: The onset of fever may indicate that the body is fighting an infection.
Red Streaks: Red streaks extending from the blister outward, which may indicate a spreading infection.

4. Pre-existing Medical Conditions:

Diabetes: Individuals with diabetes should be particularly cautious about any skin injury, as they are at higher risk of infections and delayed healing.
Compromised Immune System: People with a weakened immune system (e.g., due to HIV/AIDS, chemotherapy treatments, etc.) should consult a doctor at the first sign of infection.

5. Location of the Blister

Sensitive Areas: Blisters in sensitive areas such as the eyes, mouth, or genitals require immediate medical attention.

Basic Care and When to Seek Help

Basic Care:

Do Not Pop the Blister: Keep the blister intact to prevent infection.
Clean and Protect: Gently wash the area with soap and water, and cover it with a clean bandage.
Keep the Area Dry: Avoid excessive moisture and change bandages regularly.

When to Seek Help:

  • If you experience any of the mentioned warning signs.
  • If the blister shows no signs of improvement after a few days.
  • If you have a medical condition that could complicate blister healing.
