Suggestions: Hello, tinea pedis is an extremely common clinical occurrence in the feet and (or) hands of the skin ringworm disease. Caused by pathogenic filamentous fungal infection, tinea pedis is more common than tinea cruris. It can be classified as keratosis pilaris, blistering, papulosquamous, intertriginous and tinea corporis, or a combination thereof. This disease has a tendency to be infectious, its occurrence and close contact with the patient's hands and feet and supplies, such as slippers, bath tubs, foot wipes and so on have a great relationship. Tinea cruris is often transmitted from the patient's own tinea pedis. Treatment suggestions can be terbinafine, miconazole or ketoconazole cream applied to the affected area, 2-3 times a day. In case of erosion, 2% gentian violet liquid can be applied externally. But due to the fungal infection in the deep skin, external drugs are difficult to cure. To completely cure tinea versicolor, you should go to the dermatology department of a hospital and use oral antifungal drugs under the guidance of a doctor, such as itraconazole, fluconazole and so on.
