Chilblains are a very common disorder of the foot in the cooler environments. Chilblains are because of a poor result of the tiny arteries to alterations in temperature. Normally once the toes get cool the small blood vessels within the skin constrict to help keep the body’s central temperature at a stable level. Normally, when the toes gets warm, these arteries expand to provide more blood circulation to the skin to distribute the warmth. Within a chilblain, those tiny arteries continue to be constricted and don't open straight away. This contributes to waste material deposits within the skin which then result in the release of inflamation related chemicals. Ultimately the arteries do open up, producing an inflammatory reaction.
The reason behind this problem with the way the blood vessels react to the change in temperatures are not known. They simply apparently occur in some individuals and not in others. They are more prevalent in females revealing that there could be a hormonal element to them. Chilblains can, however, occur in men, but just less often.

They are unknown in the hotter climates.
A current unique finding which has developed fairly recently is the fact that you will find a high prevalence of chilblains in people who have COVID-19. The coronavirus illness raises the reactivity of the vascular system, so it may very well be noticed how this may predispose to chilblains since they're an issue of the reactivity with the small arteries. On the other hand, some have challenged this by implying that the chilblains might not be immediately connected to COVID-19 however are more a problem of the changes in lifestyle, such as staying without footwear more in centrally heated residences because of the lockdown belonging to the outbreak. The clinical features and treatments for the chilblains linked to COVID-19 is much like the regular type of chilblains.
Even though they primarily occur on the foot, they do once in a while impact the ears and nose. These to begin with show up as reddish and itchy sore around the toes which can be uncomfortable. If they become long-term and continue occurring chilblains take on a dark bluish colour.

When the toes get colder, after that you need to let them warm up gradually to ensure the blood vessels are given a chance to open up as they get used to the temperature.
