Chilblains are caused by the skin being in a low temperature environment. If chilblains occur, the likelihood of recurrence is very high, but it is not absolute. After experiencing chilblains once, if the environmental temperature is relatively low every year afterward and one does not keep warm sufficiently, it is basically possible for the chilblains to recur annually. However, if the climate temperature rises in subsequent years and one pays attention to keeping warm, it is also possible that chilblains will not reappear.
