Common Causes of Blisters

Monday, 17 December 2018 00:00

Research has shown blisters to be the most common medical condition among marathon runners. This may be a result of continued friction caused from the sock or shoe that is worn while running. As the skin becomes gradually damaged, the body creates a bubble containing fluid to act as a natural protectant. Research has shown similarities between people who commonly get blisters. These similarities may include performing vigorous activities that may consist of repetitive force, such as jumping and running; shoes that may fit incorrectly; or possibly from feet that have an unusual shape. There are measures that may be taken to possibly prevent blisters, including wearing shoes that are comfortable and fit properly, applying powder in shoes and socks, or taping the feet where a blister may occur. If you have a blister that is recurring and causes pain and discomfort, speak with a podiatrist who can offer proper prevention and treatment solutions.

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. Harry I. Zirna of Lockport Foot Care, PLLC. Dr. Zirna 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.
