Blisters are defined as a small pocket of fluid on the upper layers of skin. It is a defense mechanism of the body that builds between the epidermis and dermis. Fluid buildup in this pocket serves as a "cushion," protecting the skin tissue underneath until it heals and new skin is re-created. They can be quite painful.
Blisters are caused by burning (mostly sunburns and thermal burns), chemical exposure, freezing, infection, or friction (the most common). The most common friction blister is caused by shoes, particular ill-fitting or shoes that are inappropriate for the intended use.
The best treatment for blisters is to prevent them altogether, wearing well-fitting shoes, keeping feet dry, and wearing socks that manage moisture.
Blisters commonly do not require medical intervention, and will heal on their own.
Treatment
1. Find and address the cause of the irritation.
2. May place a bandage over the blister to help prevent further irritation.
3. An emollient may be applied to keep the skin soft as it heals. Aloe Vera is an excellent herbal intervention.
4. Soaking the blister in warm water helps with pain relief.
5. It is crucial to keep the blister unbroken and intact, and to allow the blister to break naturally.
6. Keep a close eye on the blister for signs/symptoms of infection.
