Blisters typically form as a natural response to a skin injury, often emerging on the feet due to friction from footwear. They create a protective fluid-filled sac that acts like a bandage, shielding the injured skin and facilitating the healing process. However, when the blister's protective covering breaks, it becomes susceptible to infection. An infected foot blister can result in specific symptoms, including the presence of pus and a warm sensation upon touch. Neglecting an infected blister also can result in a potentially dangerous bacterial skin infection. Often painful infections originating from a blister, whether bacterial, viral, or fungal, may spread to other parts of the body. This may potentially lead to sepsis, which is a life threatening bloodstream infection. Recognizing the signs of an infected foot blister includes checking for warmth, an unpleasant odor, pus discharge, or pain and swelling that surrounds the blister. Bleeding when touched or a lack of healing progress are also concerning indicators. If you have a foot blister and you suspect it is infected, it is strongly suggested that you make an appointment with a podiatrist to have it medically evaluated and treated.

Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact the podiatrists of Dr. Siegerman & Associates. Our doctors can provide the care you need to keep you pain-free and on your feet.

Foot Blisters

Foot blisters develop as a result of constantly wearing tight or ill-fitting footwear. This happens due to the constant rubbing from the shoe, which can often 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.

How Do Blisters Form?

Blisters on the feet are often the result of constant friction of skin and material, usually by shoe rubbing. Walking in sandals, boots, or shoes that don’t fit properly for long periods of time can result in a blister. Having consistent foot moisture and humidity can easily lead to blister formation.

Prevention & Treatment

It is important to properly care for the affected area in order to prevent infection and ease the pain. Do not lance the blister and use a Band-Aid to provide pain relief. Also, be sure to keep your feet dry and wear proper fitting shoes. If you see blood or pus in a blister, seek assistance from a podiatrist.
