When the upper layer of skin has been damaged, the body’s natural defense mechanism can form a blister for protection. It is defined as a small area that resembles a bubble and is filled with liquid that cushions that raw skin as the healing process occurs. Blisters generally develop from excessive friction and can be quite painful and uncomfortable. Wearing shoes and socks that do not fit correctly is a common cause of blisters. There are some patients who have specific medical conditions that can cause blisters. These can include eczema and psoriasis, in addition to developing an allergic reaction to an insect bite. It can be beneficial to cover the blister with a protective covering while accomplishing daily activities, which may help to prevent premature popping and draining. If you have a blister on your foot, please speak with a podiatrist who can offer you treatment techniques that can possibly avoid an infection from developing. 

Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact Roy Moeller, DPM of Foot & Ankle Physicians West. 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.
