A blister might not be healing for a few reasons, including infection and continued irritation. You should seek medical attention if your blister doesn't improve within a few days or shows signs of infection.
Here's a more detailed breakdown:
-
Infection: An infected blister will often appear red and swollen around the affected area. The fluid inside might change from clear or bloody to a white or yellowish color. This indicates the presence of pus, a sign your body is fighting an infection.
-
Continued Irritation: If the blister continues to be rubbed or bumped, it won't have a chance to heal. This is a common cause for blisters on feet from shoes that don't fit properly.
-
Underlying Medical Conditions: Certain medical conditions, such as diabetes or peripheral artery disease, can impair circulation and slow down the healing process.
-
Poor Hygiene: Not keeping the area clean can increase the risk of infection and hinder healing.
When to See a Doctor:
It is important to seek medical advice if:
- The blister shows signs of infection (redness, swelling, pus).
- You have diabetes or a compromised immune system.
- The blister is extremely painful or large.
- The blister does not improve after a few days.
- The blister recurs in the same location.
Taking steps to protect the blister, keep it clean, and avoid further irritation are all essential for optimal healing. If concerns persist, seeking professional medical advice is recommended.
