Athlete’s foot (tinea pedis) can be a stubborn condition to manage. Several different fungi are the culprits, and in some cases, the infection can spread to the groin area (tinea cruris). These organisms thrive in warm moist regions of the body where they proliferate first on the surface and then invade into the deeper layers of the skin. The infection usually begins in between the toes and spreads to the bottom and sides of the foot. If the fungus advances under the nail, it can lead to nail discoloration and disfigurement. Wear shoes made with natural materials or those that allow ventilation. Use a foot powder that contains an antifungal ingredient, and as much as possible, keep your feet dry. Follow good daily hygiene by washing your feet, especially at night, and allow them to dry completely. Change your socks everyday and whenever they become damp with sweat. Avoid spreading or coming into contact with the fungus by wearing flip flops or sandals in public showers and swimming pool areas. Don’t share personal items, such as towels, footwear and clothing with others.
