Why Do Blisters Develop on the Feet?

Tuesday, 15 November 2022 00:00

A blister is the body’s natural defense against skin that has become injured or burned. It appears like a small bubble that is filled with liquid and acts as a protective barrier between the skin and the environment until new skin has formed underneath it. Blisters develop for various reasons, including excess friction that happens from wearing shoes and socks that don't fit correctly, in addition to an allergic reaction from an insect bite. Some people have medical conditions that may produce blisters, including eczema and psoriasis. Possible infection may be avoided when the blister is not prematurely popped. The blister will gradually drain when the area is healed, and the skin will be a light pink until it returns to its normal color. It is advised that you consult with a podiatrist if you are afflicted with continuous blisters, who can advise you on what types of shoes to buy, or what you may be allergic to.  

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 Foothill Podiatry 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.
