Chilblains are a frequent painful skin disorder that frequently can affect the feet, but can arise on the fingers, ears or nose. They are more prevalent in wintry climates but are not necessarily because of the cold. They are due to there being a too fast warming of the skin after it has been cool. As a result of demands in the surface of the skin as the skin gets warm the capillaries normally open up and increase the circulation of blood. For a chilblain these kinds of blood vessels stay closed down for a longer time starting an inflammatory problem. Gradually the blood vessels do open up to improve the circulation of blood. This particular defective reaction of the small arteries to the alterations in temperature triggers several inflamation related toxins to get produced triggering an itching as well as inflammation.
To begin with they appear as painful reddish lesions on the skin which are itchy. After a while chilblains can turn into long term and turn into a more dark blue/black colour. They could ulcerate and an infection may occasionally occur in them. The easiest way to manage chilblains should be to stop them happening. This often will mean not necessarily allowing the foot to get cold and when it can get cold, having the skin warm-up slowly so the small blood vessels have plenty of time to adapt to that change in temperature. After a chilblain has developed it needs to be taken care of. Footwear should not be so small that they raise the strain on it and cushioning might need to be employed to protect it. Footwear as well as hosiery which help preserve heat ought to be used wherever possible. There are a variety of ointments that can be used to take care of chilblains that can help encourage the circulation and remove some of the waste material that develop. In the event these types of simple methods don't assist, then recommendations from a podiatric doctor, especially if the patch has broken down, on how to manage it is well-advised.
