When itching occurs on the bottom of the feet, the first step is to find the cause and then carry out targeted treatment in order to achieve significant results. If there is foot eczema, which is more itchy at night, and some patients have cracked feet, you can wash your feet with mugwort boiled in water. The other type of itching is caused by foot fungus, which usually manifests itself in itchy, peeling feet, blisters and smelly feet. It is important to ensure that the shoes are hygienic, with attention to disinfection, ventilation and sunlight, before applying medication for foot fungus.
