Friction is typically the principal cause of blisters on the feet. They can occur from wearing shoes that do not fit properly, which may cause rubbing against the heel or toes. Additionally, they can also form as an allergic reaction to an insect bite, or from severe sunburn or frostbite. They are defined as small bubble-like areas that are filled with clear fluid which protects the damaged skin. It generally drains naturally, as the skin heals and is replaced by new skin. If the blister should become infected, the fluid may be filled with pus or blood, and should be treated immediately. It is helpful to put a covering over the blister while wearing shoes, as this may help to protect the blister as much as possible while the healing process begins. If you frequently get blisters on the feet, it is advised that you speak to a podiatrist who can offer proper treatment options.

Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact Shaun J. Limon, DPM and Lisa Griffith-Limon, DPM of Limons Foot & Ankle Care. 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.
