Chilblains can be a very frequent problem of the foot in cooler environments. They are almost unheard of in warmer climates. They are a painful reaction of the blood circulation in the toes after a foot is cold and is warmed up too fast. Due to this problem with the blood circulation not reacting, there is an inflamation related response leading to small red and itchy skin lesions on the toes. As the problem becomes more persistent the skin takes on a painful darker discolouration because harmful toxins develop.
The ideal treatment of chilblains is preventing them. Initially, use good hosiery and footwear so that the foot does not get too cool. In the event that the foot does get cold do not put it in from of the heat source so that it gets warm too quickly. The foot should be able to warm up slowly so the circulation has time to adjust to the changes in temperature. After a chilblain does develop it must be protected so that it can heal up, especially if the skin is damaged. Keep it covered to protect it from trauma from the shoe. Soothing chilblain creams can be used to promote the blood circulation and help eliminate the harmful toxins which have accumulated in the skin which are causing the inflammation and congestion. Care also needs to be taken to protect against further chilblains developing, so the methods that should be used to avoid them should be used even more. It is possible to develop another one before the first one has healed up turning this into a chronic condition. If the local measures to take care of the problem don't help, there are some drugs a doctor may suggest which you can use to open up the blood circulation. The drugs are not specific to the foot and work everywhere, so are reserved for the more serious cases. In the very worst cases, it is not uncommon that they can be given suggestion to relocate and live in warmer climates.
