The term “ringworm” does not exist clinically, but is a common name for what is known clinically as “tinea corporis”. Ringworm can be itchy, accompanied by red papules, plaques, flaking and other lesions. Ringworm can be treated with topical or systemic medications. 1. Symptoms: The lesions are initially red patches with papules and pimples, with clear borders, the edges expanding outward, the center tends to subside, and may be accompanied by flaking. Patients are often conscious of itching, can be caused by long-term scratching and stimulation of local eczema-like or moss-like changes. 2. Treatment: commonly used topical drugs are various azoles, acrylamines and other antifungal drugs, such as naftifine ketoconazole cream. Commonly used systemic drugs are itraconazole, terbinafine and so on. Generally, the combination of external drugs and systemic drugs has better efficacy. In addition, you need to pay attention to personal hygiene in daily life to reduce the chance of infection. Patients with ringworm should take medication under the guidance of a professional doctor, and should not use medication on their own.
