T69: Other effects of reduced temperature
T69.1: Chilblains
The vessels in the body can be constricted and dilated as needed. This regulates the distribution of heat in the body, among other things. If you are prone to chilblains, then this regulation of heat may not be working properly.
Chilblains typically form on the fingers, toes or face initially as round spots on the skin. The affected skin may be bluish in color for an extended period of time. The affected areas of skin may eventually turn blue or reddish and become painful when exposed to the cold again. The affected areas of skin may also swell or lumps may form. When the skin warms up again, the chilblains may also itch or burn. Additionally, blisters or sores may then form on the affected area.
