Athlete’s foot is a common fungal infection of the skin. It can be itchy, red or flaky with blisters and is sometimes accompanied by a burning sensation.
Athlete’s foot is caused by dermatophyte fungi, which feed on keratin found in the outer layers of skin. The infection often begins between the toes, where moisture can easily become trapped. Early symptoms typically include itching, redness, and peeling skin, but as the infection progresses the skin may become cracked, sore, or blistered.
Although athlete’s foot is usually mild, it can spread to other areas of the foot or even to the toenails if left untreated. Proper diagnosis and treatment can help clear the infection and prevent it from recurring.
