Blisters are fluid-filled bubbles that can form on the feet to protect the skin underneath. Friction from a shoe, or socks that are too tight or loose, rubbing against a part of the foot along with movement can cause a blister. Excessive foot moisture or perspiration can also cause blisters to form. Sprinkling some cornstarch or talcum powder into socks can prevent excess moisture from collecting. One should not pop a blister as this provides an opening for bacteria to enter and an infection can result. With irritants removed and warm water soaks, blisters will usually heal on their own. However, if a blister gets worse, becomes unusually painful, or appears infected, see a podiatrist for proper diagnosis and treatment.
Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact [one of our podiatrists](https://www.mcallenfootcenter.com/meet-our-doctors.html) of [Foot Center](https://www.mcallenfootcenter.com/). 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.
