Causes and Treatment of Foot Blisters

Tuesday, 18 April 2023 00:00

The most common cause of blisters on the foot is friction, usually between the foot and the shoe. Damage to the top skin layer can cause it to separate, leaving space for fluid to protect the underlying layers. Walking in tight shoes or wearing shoes without socks are common causes of friction blisters. They are nature’s way of protecting skin that is in danger of being damaged. Most friction blisters do not need medical attention, and if protected by a bandage, they will likely heal on their own in a few days. However, if a blister becomes infected, this may cause redness and swelling, and the blister may fill with pus or blood rather than a clear fluid. At this point, it is wise to seek medical help from a podiatrist, who can examine the blister and offer treatment options. Certain medications and protective bandages may be prescribed. It will also be beneficial to cease wearing the shoes that caused the blister to form. For further guidance, it is suggested that you consult a podiatrist.

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. Harris L. Klear of Burlington County Podiatry Associates. 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.
