A blister is a sac of fluid that develops in the upper layer of your skin when a body part, typically a toe, rubs against a hard surface like the side or top of a shoe. This is the body’s way of protecting the toe from injury. While most blisters are clear, if one becomes infected it may fill with blood or a yellowish-green pus. Generally, a blister will heal itself in a few days, especially if the activity that caused it is stopped. For instance, if you are walking for long periods in hard leather shoes, and a blister develops, it’s a good idea to change to a more open type of shoe. It's never wise to pop a blister, as that can leave you open to serious infection. If it bursts on its own, avoid removing the dead skin, but gently wrap the area in sterile gauze until it heals. Any time a blister becomes extremely painful or appears to be infected, it is important to consult a podiatrist as soon as possible for appropriate treatment options.
Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact one of our podiatrists of Jill Einhorn, DPM and James Einhorn, DPM. Our doctors can provide the care you need to keep you pain-free and on your feet.
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.
