A blister is the body’s natural defense mechanism in protecting the top layer of the skin after it has been damaged. It is a small bubble of fluid that forms over the affected area of skin, and provides the necessary cushioning for the damaged tissue. The majority of blisters will drain once the healing process is completed, and this may take several days. There are different reasons why blisters may form, including medical conditions such as impetigo, allergic reactions to insect bites, sunburn, or frostbite. Blisters that occur on the feet are often caused by friction. This may come from wearing shoes and socks that do not fit correctly, in addition to having feet that are sweaty for the majority of the day. If you have a blister that will not heal or has become infected, it is advised to seek the counsel of a podiatrist who can guide you toward proper treatment.

Blisters may appear as a single bubble or in a cluster. They can cause a lot of pain and may be filled with pus, blood, or watery serum. If your feet are hurting, contact one of our podiatrists of Piedmont Foot & Ankle Clinic. Our doctors can provide the care you need to keep you pain-free and on your feet.

Foot Blisters

Foot blisters are often the result of friction. This happens due to the constant rubbing from shoes, which can lead to pain.

What Are Foot Blisters?

A foot blister is a small fluid-filled pocket that forms on the upper-most layer of the skin. Blisters are filled with clear fluid and can lead to blood drainage or pus if the area becomes infected.

Symptoms

(Blister symptoms may vary depending on what is causing them)

• Bubble of skin filled with fluid
• Redness
• Moderate to severe pain
• Itching

Prevention & Treatment

In order to prevent blisters, you should be sure to wear comfortable shoes with socks that cushion your feet and absorb sweat. Breaking a blister open may increase your chances of developing an infection. However, if your blister breaks, you should wash the area with soap and water immediately and then apply a bandage to the affected area. If your blisters cause severe pain it is important that you call your podiatrist right away.
