An infected foot blister can develop when the protective skin barrier is broken, allowing bacteria to enter the wound. Common causes include poor hygiene, prolonged moisture, friction from wearing tight footwear, or walking long distances. Individuals with a weakened immune system or chronic conditions, such as diabetes, are at greater risk. When a blister becomes infected, it may appear red, swollen, and warm to the touch. The area might produce cloudy or yellow drainage, and pain often increases rather than improves. In more severe cases, the surrounding skin can harden or darken, and red streaks may develop, indicating the spread of infection. Recognizing these signs early is essential, as untreated infected blisters can lead to deeper tissue infections. If you have a foot blister that has become infected, it is suggested that you contact a chiropodist who can effectively treat this condition.
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 chiropodists from The Footcare Centre. 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.
