Blisters form when the skin is injured and are the body’s way of protecting itself from further damage. A blister is a bubble of fluid that collects to cushion the injury so the underlying skin can heal. Blisters show up on the feet when there is friction from shoes. If a blister breaks, bacteria can enter the wound and an infection can develop. This can be painful and dangerous if left untreated. Sepsis, or an infection can enter the bloodstream and be life-threatening. Most blisters are tender or painful when they occur but when one is infected, it is more apt to be warm, have oozing pus, have a foul smell, and be swollen. If you have a blister that appears to be infected, bleeds when you touch it, or does not seem to be healing, it is suggested you contact a podiatrist for an examination and proper treatment.

Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact Dr. Jennifer Woo of California. 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.
