Possible Causes of Blisters

Monday, 21 October 2019 00:00

Friction is typically the principal cause of blisters on the feet. They can occur from wearing shoes that do not fit properly, which may cause rubbing against the heel or toes. Additionally, they can also form as an allergic reaction to an insect bite, or from severe sunburn or frostbite. They are defined as small bubble-like areas that are filled with clear fluid which protects the damaged skin. It generally drains naturally, as the skin heals and is replaced by new skin. If the blister should become infected, the fluid may be filled with pus or blood, and should be treated immediately. It is helpful to put a covering over the blister while wearing shoes, as this may help to protect the blister as much as possible while the healing process begins. If you frequently get blisters on the feet, it is advised that you speak to a podiatrist who can offer proper treatment options.

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. Anna Petrov of Family Foot & Ankle Care. Our doctor 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.


(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.
