How Does a Blister Form?

Blisters that develop on the feet can make it difficult to walk and complete daily activities. When the skin is irritated, the body’s natural healing response is to protect the damaged area by forming a small bubble over it that is filled with fluid. As new skin develops, the blister will gradually drain, and is no longer needed. Blisters generally develop from excess friction that is caused by wearing shoes or socks that do not fit correctly. Additional reasons why they can form can come from existing medical conditions such as psoriasis and eczema. Effective prevention techniques can include wearing comfortable shoes, checking the feet for signs of rubbing, and removing the shoes if discomfort is felt. If you would like additional information about how to treat and prevent blisters, please consult with a podiatrist.

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 Cleveland Foot & Ankle Clinic. Our doctors 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.

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.
