Blisters are small, fluid-filled bumps on the skin that form in response to trauma. The most common cause of blisters on the feet are shoes rubbing repeatedly against the skin. However, there are a variety of other reasons you may have developed a blister. These can include burns or sunburns, frostbite, eczema, allergic reactions, exposure to poison ivy, viruses that cause chicken pox or cold sores, and various diseases or infections. If you have a foot blister and can’t pinpoint the cause, or if your blister is draining pus, red in color, warm or painful, or if you have a fever, diabetes, or circulatory problems, it is strongly recommended that you visit a podiatrist. A podiatrist can examine and treat blisters on the feet and provide the appropriate treatment.

Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact Dr. Robert Graser of Graser Podiatry and Bunion Surgery Institute. Our doctor 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.
