What should I do about tinea cruris (jock itch)?

Tinea corporis is a common skin disease caused by fungal infection. The following treatment methods can be used for tinea corporis: 1. **Topical medication**: Select antifungal drugs such as clotrimazole, ketoconazole, terbinafine, and apply them locally to control disease progression. 2. **Oral medication**: For recurrent or severe cases of tinea corporis, systemic treatment with oral antifungal agents such as itraconazole and terbinafine may be considered. 3. **Maintain cleanliness and dryness**: Since tinea corporis easily grows in moist environments, keeping the affected area clean and dry is very important. Frequently use dry towels to dry the affected area and wear loose, breathable clothing. 4. **Combined therapy**: Under a doctor's guidance, different types of antifungal medications may be used together to improve treatment effectiveness and reduce recurrence rates. 5. **Personal hygiene**: Avoid close contact with infected individuals and do not share personal items such as towels and bathtubs to prevent cross-infection.
