Blisters form between layers of injured skin as a way of cushioning the injury and protecting it from further damage. When friction or some other irritant damages the upper layer of skin (epidermis), it can tear away from underlying layers of skin. The space that is created between the layers then fills up with fluid (serum). Most blisters occur as a result of friction caused by ill-fitting shoes or socks. Other causes of blisters include burns, frostbite, irritants such as insect bites, chemicals and other toxins. Medical conditions like diabetic neuropathy and eczema, as well as certain autoimmune deficiencies, can weaken the outer layer of skin which increases the risk of blisters forming. Aside from removing pressure from the affected area, it is best to leave a blister alone to allow it to heal naturally, which usually happens within a few days. However, if the blister worsens by becoming discolored or excessively inflamed, it may indicate that an infection is present and a podiatrist should be consulted right away.

Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact Dr. Kirk Sherris of Liberty Bay Foot & Ankle. 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.
