Your symptoms are suggestive of fungal infection (ringworm/tinea). You can usually treat mild cases with antifungal creams such as Clotrimazole, Terbinafine, or Luliconazole applied as directed for 2?4 weeks. Keep the area clean and dry, avoid scratching, do not share towels or clothes, and wear loose cotton clothing. Avoid using steroid-containing combination creams without a doctor?s advice, as they can worsen fungal infections. Please consult a dermatologist if the rash spreads, involves multiple areas, recurs frequently, or does not improve within 2 weeks.
