Ringworm is a fungal infection of the skin on the inner thighs, and treatment for ringworm should be thorough to kill the fungus and prevent fungal infection. Currently, for more limited dermatophytosis, topical topical application and application is mainly done with econazole suppositories and also compound ketoconazole suppositories, dacrynic acid, and clotrimazole. In addition, if the onset of ringworm is more severe or even accompanied by bacterial infection, it is important to first apply boric acid ointment or other anti-inflammatory ointment topically to control bacterial infection, then apply antifungal ointment such as Dakine to inhibit fungus, and also treat with oral itraconazole and other antibacterial fungal medications. It is also important to take care when treating ringworm that the fungus is not stimulated by local actions such as cautery or massage.
