Causes and Contents of Foot Blisters

Foot blisters are fluid-filled sacs that form on the skin's surface as a result of friction, heat, or pressure. They often appear on the feet when shoes rub against the skin or when the skin is exposed to excessive moisture. Activities such as walking, running, or hiking can increase the likelihood of developing blisters, especially if new or ill-fitting shoes are worn. Inside a foot blister is a clear, watery fluid called serum, which forms as the body’s natural response to protect the damaged skin underneath. The fluid helps cushion the area, allowing the skin to heal. In some cases, blisters may become filled with pus if infected. Foot blisters can be more than bothersome. If this applies to you, it is suggested that you contact a podiatrist who can treat it safely, and offer effective blister prevention 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 one of our podiatrists of Carolina Foot & Ankle Specialists. Our doctors can provide the care you need to keep you pain-free and on your feet.

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.
