I have had a very itchy skin infection in my groin area since May, possibly caused by wet underwear. I have already tried using Itch Guard, Soframycin, and Bitex creams, but the infection has not cleared. What effective medicine or ointment should I use to treat this persistent infection?

This persistent itch is likely a fungal infection, commonly triggered by trapped moisture. The creams you previously tried included an antibacterial agent and strong irritants, which do not cure fungal infections and can sometimes worsen them. To treat this effectively, keep the area clean and completely dry. You can apply an over-the-counter antifungal cream containing generic clotrimazole, miconazole, or terbinafine twice daily for 2 to 4 weeks. Avoid tight clothing and change out of wet clothes immediately. Since the infection has persisted since May, it is highly recommended to consult a doctor or dermatologist, as you may require prescription-strength oral antifungal medication.
