Athlete’s foot is a fungal infection that can cause cracking, scaling and itching, particularly between the toes. Fungi thrive in warm, damp environments and can spread through surfaces or footwear. MedlinePlus explains that over-the-counter antifungal creams or powders can help control the infection. MedlinePlus
Treatment and prevention address different needs: medicine targets the infection, while drying feet and replacing wet socks reduce conditions favourable to fungi. The American Academy of Dermatology recommends footwear in communal showers, allowing shoes to dry between uses, and not sharing towels or shoes with an infected person. AAD
Do not dismiss swelling, warmth and pain, especially with red streaks, pus or fever, as ordinary itching. MedlinePlus advises prompt medical contact because these may indicate bacterial infection. Persistent or recurring symptoms also need assessment. This general guidance cannot diagnose a rash from internet photographs. MedlinePlus
