Blisters on the Feet

Blisters on the feet are fluid-filled sacs that form on the outer layer of the skin, typically caused by friction or pressure. They can occur due to wearing ill-fitting footwear, prolonged walking or running, excessive moisture, or repetitive rubbing against the skin. Blisters often manifest as a raised area filled with clear fluid, which may be painful or tender to the touch. In some cases, they can cause discomfort while walking or wearing shoes. While blisters often heal on their own within a few days, they can sometimes lead to complications such as infection if not properly managed. It is important to keep on top of foot blisters should they form. Keep the area clean and protected to prevent infection. If you have a blister that becomes red, swollen or shows signs of pus, or if you develop recurrent or large blisters that cause severe pain, it is suggested that you schedule an appointment with a podiatrist for care to prevent further complications.

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 Ronald Pieroni, DPM of Bolingbrook Foot and 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.


(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.
