Unfortunately, people don’t always immediately realize that they have developed a fungal infection. "While people think of athlete’s foot as the cracking and blistering between toes, it can also appear as dry, flaky skin on the back of the heels and little bubbles or bumps on the arch area or on the sides of the foot," Ravick says.
Nail fungal infections usually appear as a yellow or brownish discoloration of the toenail and can become thick and disfigured. They usually occur when a skin infection of the feet spreads to the nails, or if the nail is damaged or cracked. Cutting the toenails straight across and avoiding pointy shoes that crush the toes may help prevent ingrown toenails and minimize nail damage that can lead to infections.
Fungal infections can be treated with a range of medications, including creams such as Lotrimin, a nail lacquer such as Penlac or oral antifungals such as Lamisil or Sporanox. Since nail fungal infections can be particularly resistant, one may ultimately need a podiatrist remove the affected nail.
People with fungal infections are at high risk for re-infection, Ravick says, especially if they don’t treat their shoes. "When people have fungal infections, microscopic skin and nail pieces get into your socks and shoes," he says. "You’re figuring people wash their feet and socks, but they don’t wash their shoes. I have my patients spray all of their shoes once a week with an anti-fungal spray."
Dryness Dangers
The colder months also leave people more vulnerable to dry and even cracking feet. The lack of moisture in the air and heavy socks and shoes may prohibit dead skin from shedding, leading to flaky feet.
