What Is a Blister and Why Do They Form?

Monday, 02 November 2020 00:00

Patients who have developed blisters on their feet are often aware of how uncomfortable they can be. Blisters can cause difficulty walking, running, or completing daily activities. Blisters are defined as the body’s natural defense response to protect skin that has become damaged from excess friction. It can be beneficial to wear socks and shoes that fit properly, as this may help to reduce existing friction. Additionally, it may help to remove shoes while resting, which can give the feet the opportunity to dry off. Mild relief may be found when a protective pad is worn over the blister, as this may prevent premature draining. If you have a blister on your foot, it suggested that you speak with a podiatrist who can provide you with proper treatment.

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. Janet Leicht of New Jersey. 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.
