Athlete's feet

Athlete's foot (also known as tinea pedis or ringworm of the foot) is a common skin disease that affects the skin on the feet. It is caused by a fungus that grows on or in the top layer of skin.

Causes

Athlete's foot is caused by a group of mold-like fungi called dermatophytes that feed on dead skin and nails. These fungi thrive in warm, moist environments, such as the inside of a sweaty shoe. Athlete's foot is contagious and can be spread through direct contact or by touching surfaces contaminated with the fungus.

Symptoms

The symptoms of athlete's foot can vary from person to person. Some common symptoms include:

• Itching, stinging, and burning between the toes
• Itchy blisters
• Cracking and peeling skin, especially between the toes and on the soles of the feet
• Dry skin on the soles or sides of the feet
• Raw skin on the feet
• Discolored, thick, and crumbly toenails
• Toenails that pull away from the nail bed

Treatment

Treatment for athlete's foot includes over-the-counter antifungal creams, sprays, and powders. If these treatments do not work, a doctor may prescribe stronger antifungal medications. Keeping the feet dry and practicing good foot hygiene can help prevent athlete's foot.

Prevention

Prevention of athlete's foot includes:

• Keeping the feet dry, especially between the toes
• Changing socks regularly
• Wearing light, well-ventilated shoes
• Avoiding walking barefoot in public areas
• Using antifungal powder in shoes and on feet
