What Is a Blister and Why Do They Develop?

Monday, 12 April 2021 00:00

Many people have had blisters on their feet at some point in their lives. They can be bothersome, and may hinder performing daily activities. They generally develop as a result of excess pressure that occurs from wearing shoes that do not fit correctly, or from routinely performing the same activities which often includes running. A blister is defined as a small area on the skin that resembles a bubble, and is filled with liquid. This is the body’s natural defense for protection when an injury occurs that affects the skin. The blister will gradually drain as new skin forms. Runners may find it beneficial to wear a protective covering over the blisters, as this may keep the blister from draining prematurely. If you would like additional information about how to treat blisters and prevent them from developing, 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 Dr. Jeff Brooks of Oceanside Foot & Ankle Center. 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.

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.
