Causes of an Infected Foot Blister

An infected blister on the foot can develop due to several common but preventable causes. Poor hygiene is a leading contributor, as dirt and bacteria can accumulate around the feet and create an environment prone to infection. Popping a blister with unclean or sharp objects can introduce harmful bacteria directly into the wound. Similarly, contact with contaminated surfaces such as floors or shoes can allow bacteria to enter the blister, especially if the skin has already been compromised. Symptoms of an infected blister include increasing redness surrounding the area, swelling, pain, and warmth to the touch. The blister may fill with cloudy or yellow fluid, and the surrounding skin might emit an unpleasant odor. If you have a blister on your foot that has become infected, it is suggested that you promptly contact a chiropodist who can offer effective relief and prevention tips.

Blisters can usually be treated at home, however, if you have recurring blisters or experience significant discomfort or pain, please consult with one of the specialists from Thornhill Foot Clinic. Our chiropodists will assess your condition and provide you with quality foot and ankle treatment. 

What Is a Blister? 

A blister is a small pocket of fluid in the upper skin layers and is one of the body’s natural responses to injury or pressure. Blisters can also result from burns, fungal or viral skin infections, and the feet are particularly prone due to ill-fitting footwear and friction. Friction on the skin causes the upper layer of skin to separate from the lower layers. The space that this separation creates then becomes filled with a liquid called serum, which protects the lower layers of skin. 

Treatment 

If you notice a blister on your foot, you can cover it with a soft bandage or dressing to protect it. Popping the blister is discouraged. Doing so exposes the raw skin underneath it to bacteria and also raises the risk of infection. If a blister pops naturally, let it drain before covering it with a bandage. Blisters usually heal on their own or with home treatment, however, if your blister is recurring, very painful, or appears infected, it is recommended that you see a chiropodist for treatment. 

Prevention

You can help to prevent blisters by wearing comfortable, well-fitted shoes. Keep your feet dry by wearing moisture-wicking socks and dust your feet with talcum powder if they tend to get sweaty. If you have areas on your feet that are more susceptible to blisters, you might be able to prevent the blister from forming by covering it with a pad.
