Most blisters form on the feet due to friction. As you walk, your shoes or socks may rub against a small area of skin, damaging it. A pocket of fluid builds up underneath the damaged skin to shield the deeper layers of skin from further damage. Friction blisters are best left alone and footwear and activity modifications are often adequate for treating symptoms and preventing future blisters. However, not all foot blisters are caused by friction. Blisters can also occur on the feet due to allergic reactions, exposure to certain chemicals, skin conditions like eczema, frostbite, sunburn, and fungal, viral, or bacterial infections. If you frequently have blisters on your feet, a podiatrist can help you determine the cause of your blisters and find the best treatment for you.

Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact John M. Fanelly, DPM of Northeast Philadelphia. 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.
