Blisters are small pockets of fluid that form under the skin. On the feet, they can develop when repeated friction causes the skin to become irritated. Shoes that rub against the heel, toes, or other areas of the foot can create this friction. Blisters can also result from burns, skin reactions, or other conditions. A typical blister contains clear fluid and can cause pain or tenderness. Blood blisters can appear red or dark because small blood vessels under the skin have also been damaged. The location and appearance of a blister can provide clues about what caused it. Some blisters heal without causing further problems, while others can become painful or infected.
A podiatrist can examine a foot blister to determine its cause and check for signs of infection or other skin problems. An infected blister can become hot, swollen, and painful. Yellow or green fluid can also develop inside the blister. Redness surrounding the area can be another sign of infection. A podiatrist can evaluate these changes and determine the appropriate treatment. Professional care can also be helpful when blisters are very painful, keep returning, or appear without an obvious cause. Repeated blisters can sometimes point to an issue with the way shoes fit or how pressure is placed on certain areas of the foot.
Treatment depends on the blister and what caused it. A podiatrist can protect the affected area, address pressure or friction that is contributing to the problem, and determine whether the blister requires drainage or other treatment. When an infection is present, a podiatrist can recommend appropriate care to address it. A podiatrist can also evaluate recurring blisters to identify factors that could be contributing to them. Early evaluation can help prevent a small blister from becoming a larger foot problem. If you have developed foot blisters, it is suggested that you schedule an appointment with a podiatrist for effective relief and prevention tips.
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 Alice Kim, DPM of 101 Foot and Ankle. Our doctor can provide the care you need to keep you pain-free and on your feet.

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.

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.
