When skin becomes damaged due to friction, a small bubble of fluid can form in the epidermis in order to protect the layers of skin beneath it which allow the skin to heal. Blisters are typically filled with a clear serum, but in some cases where there is excess pressure or friction, the sac may fill with blood. If the blister becomes infected, pus may collect in the blister. An infected blister may also become red, swollen, or painful. Most blisters will heal on their own if they are left alone, allowing the new skin to grow underneath it. Blisters should not be popped, as they provide a protective barrier that keeps bacteria away from the damaged skin to ward off further damage and infection. Wearing shoes that fit properly and are flexible can go a long way in avoiding blisters from forming. Socks that are clean and keep moisture away from the skin are also beneficial, as moist skin can blister more easily. If a blister becomes infected, it is suggested that you contact a podiatrist who can help cure the infection, help your skin to heal, and offer preventive methods to avoid the formation of blisters.
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.

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.
(Blister symptoms may vary depending on what is causing them)
- Bubble of skin filled with fluid
- Moderate to severe pain
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.
