Blisters are small, fluid-filled pockets that form on the skin in response to trauma. Blisters on the feet are typically caused by friction from wearing ill-fitting shoes or exercising, but are also commonly caused by warts, athlete’s foot, and allergic reactions. If you have a blister, it is best to avoid popping it. The fluid inside the blister protects the raw skin underneath it, helping it heal from damage. When a blister is popped, it can be very painful and is more likely to become infected. If your blister has popped on its own, don’t peel off the top layer of skin. Leave it there and cover the blister with a clean bandage to protect it. If your blister is very painful, showing signs of infection, or leaking pus, please seek the care of a podiatrist. 

Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact one of our podiatrists of Pennsylvania Foot & Ankle. 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.
