Tinea cruris is caused by a fungal infection and generally does not heal on its own without proper treatment. In principle, fungi thrive and spread in moist environments, increasing in coverage. Besides the groin area, fungal infections might also occur on the buttocks or other body parts. Once an infection occurs, it is essential to apply antifungal cream regularly over a period to achieve a complete cure. It is also important to maintain proper dietary and lifestyle habits, avoiding public baths and swimming pools, not keeping small animals at home, and washing socks and underwear separately with sun exposure for disinfection. Additionally, it is advisable to avoid spicy and irritating foods, refrain from staying up late, and bathe more frequently.
