Chilblains are a reasonably common problem once the weather is cooler. These are a painful and itchy reaction of the smaller blood vessels in the toes to the variations in temperature. They result in a painful red area, which later becomes a dark blue color should they become chronic. Chilblains have just lately been receiving some extra press in the media as a result of them being more common in those infected with the coronovirus, being given the term, COVID toes.
Chilblains are a seasonal condition and appear in all places in which the climate gets cold enough to result in the reaction in the skin. An instance of PodChatLive had a deep discussion of the problem of chilblains:
The easiest method to manage chilblains is usually to prevent these by keeping the feet warm. If a chilblain will develop then it must be kept warm and be protected to stop the skin from breaking down. There are several chilblain creams which you can use to help to promote the blood circulation.
