Blisters on the feet are pockets of fluid that form beneath the top layer of the skin to protect the lower layers from damage. Blisters on the toes, feet, or heels may be caused by friction, usually from pressure or rubbing against the inside of a shoe. Generally, a blister is filled with clear serum, but sometimes it may be filled with blood, or even pus if it becomes infected. As a rule, a blister will go away on its own in three to seven days. As new skin grows under the blister the serum will be reabsorbed into the body and the outer skin will dry up and flake off. However, it is important to remember that popping a blister can cause infection or inhibit the healing process. Wearing shoes that are comfortable and do not rub against the skin is a sure way of allowing a blister on the foot to heal, or preventing one from occurring in the first place. If you have a particularly painful blister, or one that appears to be infected, please make an appointment with a podiatrist. Antibiotics may be prescribed to ward off the infection, and the podiatrist may safely drain the blister in a sterile setting. 

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