Blisters on the feet can take different forms depending on their cause and appearance. Clear blisters are usually filled with serum, a fluid that protects damaged skin. Blood blisters occur when small blood vessels are damaged, and infected blisters may have a yellow or white tint due to pus. Friction is the most common cause of foot blisters, especially when wearing shoes that are either too tight or too loose. Moist, warm skin increases the chances of blister formation during walking or running. Certain medical conditions, infections, or skin disorders may also trigger blisters. In rare cases, exposure to chemicals or allergens can cause the skin to blister. A chiropodist can examine your feet, identify the source of blistering, and recommend treatment to support healing. If you have problematic blisters on your feet, it is suggested that you make an appointment with a chiropodist for help.

Blisters can usually be treated at home, however, if you have recurring blisters or experience significant discomfort or pain, please consult with Cynthia Chan, B.Sc., D.Ch from Healthy Advantage Foot & Orthotic Clinic. Our practitioner 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.
