Chilblains are what is identified as a non-freezing cold problem. This is a issue that occurs in the cold but isn't a freezing cold problem such as frostbite. Chilblains are an unusual reaction of the small blood vessels in the toes to a change in temperature from cold to warmer. Typically when the foot is cooler, the blood vessels close up to conserve warmth. Generally once the feet are heated up those blood vessels have to open up to improve circulation to the tissues. In a chilblain the blood vessels remain closed up for a extended period of time and then sooner or later and instantly open up. This makes an inflammatory reaction which causes a painful red spot on the foot. After a couple of days waste material build up in the skin and the colour changes to a dark blue colour. They are usually quite painful.
An obvious way to treat a chilblain is to try and prevent them in the first place and not let them develop. You need to do this by not really allowing the foot to get cooler using cozy hosiery and protective shoes. If the foot will get cold, then it is imperative that you give time to warm up slowing to give the circulation an opportunity to react to that warming up. It is the too fast heating up of your skin which is the problem in a chilblain. If a chilblain can occur, then it really needs to be taken care of. Good warmer hosiery as well as shoes should be worn. Applying a chilblain cream to massage them supports the arteries helping with doing away with those waste materials which have accumulated. In the event the skin gets broken, then correct dressing with antiseptics needs to be used and kept getting used until it heals since there is a danger for an infection. It is next crucial that you protect against any more chilblains occuring in subsequent days otherwise there is a possibility that this will end up a persistent ailment.
