Because fungal and bacterial infections require completely different treatments, it is crucial to get a proper diagnosis first. Using an antibacterial cream on a fungal infection, or vice versa, will not help and can make it worse. For a fungal infection, over-the-counter antifungal creams like Clotrimazole or Miconazole are typically used. For bacterial infections, prescription antibiotic ointments like Mupirocin are required. To ease itching safely right now: keep the area clean and dry, wear loose cotton clothing, and avoid scratching. Please consult a doctor so they can examine the rash and prescribe the correct medication.
