A blister is a fluid-filled sac that forms on the skin due to repetitive friction. This typically arises when skin continually rubs against objects, such as the inside of shoes. The friction causes skin layers to separate, prompting the body to fill the void with fluid as a protective mechanism against further harm. Blisters can be painful, especially when wearing shoes that contribute to the friction. They are common and can be attributed to factors like poorly fitting shoes, foot deformities, sweat, prolonged exercise, or using unsuitable socks. It is advisable to refrain from popping blisters, as this exposes the wound to potential infections. Instead, protect it with a bandage and eliminate the friction source. There are other conditions with symptoms resembling blisters, such as impetigo, eczema, and burns. If you have a foot blister that does not heal in a reasonable time, worsens, or appears infected, it is suggested that you make an appointment with a podiatrist who can distinguish it from other ailments, treat it, and provide prevention tips.

Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact one of our podiatrists of The Sun Healthcare & Surgery Group. 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.
