What Is a Blister?

Monday, 18 February 2019 00:00

Patients who have suffered from blisters are familiar with the pain and discomfort they may cause. They may develop as a result of increased friction on a portion of the skin, which may come from wearing shoes or socks that fit improperly. When the skin becomes exposed, a blister will form as part of the body’s natural defense mechanism. This consists of a pocket of fluid which protects the affected area of skin. Additional reasons why blisters may develop may include allergic reactions to a bee sting or insect bite, or neuropathy which may originate from diabetes. If neuropathy is present, it may cause the patient to be unaware of existing blisters, and this may be a result of the inability to sense discomfort. When new skin begins to grow under the blister, it will generally drain on its own. If you have a blister on your foot that has become infected, it is suggested to speak to a podiatrist who can properly assist you in obtaining the correct 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 one of our podiatrists of InStride Foot & Ankle Specialists. 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.


(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.
