While most people are somewhat familiar with blisters due to having at least one in their lifetime, here are some things you may not know about these “irritating” fluid-filled bubbles. Blisters fall into one of three categories typically: clear, blood, or infected. Clear blisters are one of the most common types of blisters, and are filled with a clear serum that protects the underlying skin from further damage. When blood vessels are damaged along with skin, the blister that forms may have blood mixed in with the serum. If a blister becomes infected, it can fill with white or yellow pus. Sudden, highly concentrated friction from ill-fitting shoes rubbing against skin on the foot will typically cause a blister, while repetitive, less intense friction will typically cause corns or calluses. Intense temperatures can also cause blisters to form, as in the case of second-degree frostbite or a bad sunburn. Chicken pox, shingles, eczema and other medical conditions may cause blisters as well as exposure to certain chemicals that create an allergic reaction in the skin. If you have developed a blister, do not pop it. If it does not improve, gets worse, or looks like it might be infected, seek the care of a podiatrist.

Blisters are prone to making everyday activities extremely uncomfortable. If your feet are hurting, contact Ainsley Rusevlyan, DPM of InStride Roberson Footcare. 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.
