What Is a Blister?

Anyone who has encountered a blister on their foot is aware of the discomfort and inconvenience it can cause. A blister is defined as a small area of fluid that forms over skin that has become damaged for various reasons. A blister is the body’s natural response to healing raw skin, and it is successful in protecting the affected area until new skin has formed. A blister on the foot can be caused by excess friction, which may happen from the shoes and socks that are worn. They may be too tight and not fit well, causing the skin to endure unwanted pressure. A blister will gradually drain when the new skin has grown, and it is beneficial to refrain from popping it. If this happens, an infection may occur, and the condition may worsen. Many people choose to wear a bandage over the blister that can protect it while completing daily activities. If you develop blisters on your feet, it is suggested that you confer with a podiatrist who can offer you effective preventive techniques.

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 Dr. Yeon A. Shim of Roselle Podiatry Group. Our doctor can provide the care you need to keep you pain-free and on your feet.

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.
