What causes chilblains on the feet?

Chilblains can be a frequent unpleasant skin complaint that typically occurs on your toes, but sometimes appear on the fingers, nose or ears. Chilblains more common in cooler environments but aren't necessarily a result of the cold. These problems are caused by there being a too fast warming up on the skin once it has been cold. Due to demands in the skin surface as the tissues gets warm the arteries normally expand while increasing blood circulation. In a chilblain these kinds of arteries stay shut for longer creating an inflammatory reaction. Sooner or later they do expand to boost blood flow. This particular unusual response of the small blood vessels to the alterations in temperature triggers various inflamation related toxins to get released leading to an itching and also inflammation.

In the beginning chilblains appear as sore reddish colored patches on the skin which are itchy. Eventually they turn into long term and turn into a darker blue/black shade. Chilblains could ulcerate and an infection may also from time to time develop in them. The obvious way to take care of them is to stop them happening. This usually will mean not necessarily enabling the skin to get cold and if it can get cold, letting the skin warm up slowly so the small blood vessels have plenty of time to adjust to that change in temperature. Once a chilblain has occurred it has to be looked after. Shoes really should not be so restricted that they raise the load on it and shock absorption might need to be employed to safeguard it. Footwear and also socks that really help preserve warmth ought to be used as much as possible. There are various ointments which can be used to deal with this to help encourage the blood circulation and remove some of the waste material which accumulate. In the event these kinds of basic methods tend not to help, next help and advice from a podiatric doctor, particularly if the chilblain has broken down, regarding how to control it is recommended.
