What Causes Blisters?

Tuesday, 16 April 2019 00:00

A blister is the body’s natural defense mechanism in protecting the top layer of the skin after it has been damaged. It is a small bubble of fluid that forms over the affected area of skin, and provides the necessary cushioning for the damaged tissue. The majority of blisters will drain once the healing process is completed, and this may take several days. There are different reasons why blisters may form, including medical conditions such as impetigo, allergic reactions to insect bites, sunburn, or frostbite. Blisters that occur on the feet are often caused by friction. This may come from wearing shoes and socks that do not fit correctly, in addition to having feet that are sweaty for the majority of the day. If you have a blister that will not heal or has become infected, it is advised to seek the counsel of a podiatrist who can guide you toward proper treatment.

Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact Abeer M. Foteh, DPM of Greater Houston Foot Centers. 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.
