When a blister develops on the feet, it is the body’s natural defense for protecting damaged skin. This can happen as a result of wearing shoes and socks that do not fit correctly, which may cause pressure on different areas of the foot. A blister is a small bubble that is filled with protective fluid. It is important that it is not prematurely popped, and it will gradually drain when the new skin forms and is no longer needed. There are other reasons a blister may form, including having an allergic reaction to an insect bite or chemical substance. Additionally, medical conditions such as eczema, psoriasis, heart conditions, or immune disorders may lead to blisters forming. If you have recurring blisters on the feet, please consult with a podiatrist who can determine the reason why, and offer you methods which may help to prevent blisters in the future.

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 Anthony Ricciardi Jr., DPM of Foot & Ankle Specialists of Nevada. 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.
