If you touch something that has fungi on it, you can spread athlete's foot to other people-even if you don't get the infection yourself. Some people are more likely than others to get athlete's foot. Experts don't know why this is. After you have had athlete's foot, you are more likely to get it again.
What are the symptoms?
Athlete's foot can make your feet and the skin between your toes burn and itch. The skin may peel and crack. Your symptoms can depend on the type of athlete's foot you have.
Toe web infectionToe web infection usually occurs between the fourth and fifth toes. The skin becomes scaly, peels, and cracks. Some people also may have an infection with bacteria. This can make the skin break down even more.
Moccasin type infectionMoccasin type infection may start with a little soreness on your foot. Then the skin on the bottom or heel of your foot can become thick and crack. In bad cases, the toenails get infected and can thicken, crumble, and even fall out. Fungal infection in toenails needs separate treatment.
Vesicular type infectionVesicular type infection usually begins with a sudden outbreak of fluid-filled blisters under the skin. The blisters are usually on the bottom of the foot. But they can appear anywhere on your foot. You also can get a bacterial infection with this type of athlete's foot.
