Identifying whether a foot blister is infected involves observing certain symptoms. Signs of infection can include increased pain, redness, warmth, and swelling surrounding the blister. The blister may also appear to be filled with pus or fluid that is cloudy or discolored. If the area around the blister becomes increasingly tender or painful, or if you notice red streaks spreading from the blister, these could indicate an infection spreading through the skin. Additionally, fever and chills may accompany a severe infection. Monitoring the blister closely and seeking medical attention if you notice any of these signs is vital. Prompt treatment with antibiotics or drainage may be necessary to prevent the infection from worsening. If you have a foot blister that has become infected, it is suggested that you promptly contact a podiatrist who can treat this condition. 

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