Chilblains are what is called a non-freezing cold problem. It's a problem that occurs in the cold temperatures but is not a freezing cold injury like frostbite. They are an abnormal reaction of the small blood vessels in the foot to a change in temperature coming from cold to warmer. Typically if the foot is cooler, the arteries close up in order to save warmth. Generally when the foot is heated up those arteries need to open up to raise circulation to the skin. With a chilblain the blood vessels continue to be closed up for a lengthier interval of time and then at some point and suddenly open up. This causes an inflammatory reaction that triggers a painful reddish region on the foot. After a couple of days waste elements build up in the epidermis and the colour changes to a darkish blue colour. They are generally very painful.
The right way to address a chilblain would be to not get one in the first place. You need to do this by not really permitting the foot to get cold using warmer socks and protective shoes. If the feet will get cooler, then it is vital that you give time to warm up slowing to give the blood circulation a chance to respond to that temperatures rising. It's the too fast warming of your skin which is the problem in a chilblain. If a chilblain should occur, then it must be taken care of. Very good warm hosiery along with shoes needs to be worn. Using a chilblain cream to rub them supports the blood flow and helps with eliminating those waste products that have accumulated. Should the skin becomes broken, then appropriate dressing with antiseptics needs to be used and kept getting used until it gets better as there is a danger for an infection. It is next imperative that you prevent any further chilblains developing in succeeding weeks otherwise there exists a fairly good chance that this results in being a long-term ailment.
