Chilblains are really common in some parts of the world and are unheard of in other parts of the world. In some parts of the worldÂ chilblains are as common as the everyday cold and recognised daily. In other parts of the world they can easily get missed as they do not happen that often. The key pathophysiological mechanism underpinning chilblains is a the microcirculation not responding appropriately to warming after the foot has got cold. The exact reason of this poor response of the circulation is not known. Chilblains are not due to poor circulation or the cold, but are due to how the circulation responds to warming after it gets cold. There has been very little research done on chilblains given how common they are. There are no definitive guidelines as to the best way manage them with many having their favourite remedy. The only really effective way to deal with chilblains is to not get cold in the first place.
