Tinea pedis (athlete's foot) is a fungal infectious disease, and the treatment duration varies. If detected early, treatment can simply involve the application of topical antifungal cream, generally for a course of more than one month. If the condition has been present for a longer time and involves scaling, blistering, or even cracking, the treatment period will be longer, possibly exceeding six months. If topical antifungal creams are ineffective, oral antifungal medication can be taken, which tends to be more reliable. After recovery, it is important to prevent recurrence. Try to avoid contact with irritating substances, abstain from spicy and stimulating foods for a long time, avoid wearing slippers carelessly, and ensure that worn shoes and socks are disinfected by exposure to sunlight. If there are family members with the same condition, it is advisable to treat them together.
