When frostbite grows on the feet in winter, it is recommended that one must pay attention to keeping warm. Frostbite is mainly caused by a cold environment and poor local peripheral circulation. If the lesions at the frostbite appear, you can give vitamin E cream for external use. If it is serious, you can improve microcirculation with oral vitamin E and salvia, etc. You must pay attention to more physical exercise. If the lesions have broken down, topical application such as Conradipine cream and Xylitol cream can be given. Increasing physical exercise in general can help improve the blood circulation of the body and reduce the occurrence of frostbite. For recurring patients, you can also give suberythematic amounts of ultraviolet or infrared radiation to prevent the occurrence of frostbite. You must pay attention to keeping your feet warm in winter and choose soft, protective shoes.
