Athlete's foot (tinea pedis) is a common fungal infection that usually causes itching, peeling, cracks between the toes, and discomfort, especially when the feet stay sweaty or covered for long hours. It spreads easily in warm and moist conditions, which is why it often keeps coming back if the environment on the feet doesn't improve. Treatment usually involves antifungal creams applied regularly on the affected area and slightly beyond it for a few weeks, even after symptoms improve. Keeping the feet clean and completely dry is very important, especially between the toes. Changing socks daily, wearing breathable footwear, and avoiding tight shoes can make a big difference in preventing recurrence. Antifungal powders can also help keep moisture under control during the day. It is also important not to scratch the area, as it can spread the infection to other parts of the foot. Towels and footwear should not be shared with others. If the infection is persistent, spreading, or not improving with regular antifungal use, a doctor may consider stronger oral treatment depending on severity.
