What is the best ointment for treating tinea cruris?

Tinea cruris is caused by fungal infection of the skin cutin. It is characterized by a clear erythema at the root of the thigh, obvious inflammation around it, a tendency to heal in the center, and slight exfoliation. Treatment should choose an ointment with antifungal effect, such as terbinafine cream, naftifine ketoconazole cream or miconazole nitrate cream. If tinea cruris has been scratched and broken, purulent water can be produced. Boric acid solution wet compress can be selected. After drying, anti-fungal ointment can be applied externally. If the patient has a large rash area and diabetes, it is recommended to cooperate with oral terbinafine tablets or oral itraconazole for treatment, so as to achieve the goal of rapid cure.
