Chilblains really are a reasonably prevalent problem once the weather is colder. These are a painful and itchy reaction of the small blood vessels in the toes to the variations in temperature.

Chilblains are a seasonal condition and happen in all countries in which the environment gets cold enough to cause the response in the skin. An instance of PodChatLive had a detailed discussion of the disorder of chilblains:
