Tinea pedis is a fungal skin disease that occurs between the toes, heels, and lateral edges of the feet, and is characterized by blisters, flaking, itching, and in severe cases, erosion, oozing, and concurrent bacterial infections. The treatment is mainly antifungal, and patients should visit a hospital to avoid delaying or aggravating the condition. For milder symptoms, topical creams with antifungal effects can be used, such as naftifine ketoconazole cream, bifenazole cream, boutinafine cream, and compound ketoconazole cream. Patients with severe symptoms need to take oral itraconazole capsules or terbinafine tablets, etc. under the guidance of a doctor, and at the same time actively treat the foot fungus to avoid reinfection. If there is no obvious effect after 1-2 weeks of treatment, you need to go to the hospital dermatology department in time. Patients should avoid touching or scratching the infected parts of their hands during the treatment period to avoid spreading the infection. In daily life, it is important to wash hands and feet regularly to maintain personal hygiene. Also note that household items should be used separately and disinfected in a timely manner.
