Itchy skin when it is cold and itchy when it is hot

Frostbite is a localized inflammatory lesion caused by cold. Frostbite is a common disease in winter, especially in children, women and the elderly. Once frostbite occurs, it is often difficult to cure quickly in the cold season. It will gradually heal after the weather warms up. To reduce the occurrence of frostbite, the key is to prevent it before winter.
