Chilblains are a common problem of the foot in colder environments. They are virtually unknown in hotter climates. They are a painful reaction of the blood circulation in the toes after the feet are cold and is warmed up too quickly. Due to this issue with the blood circulation not responding, there's an inflamation related response leading to small reddish and itchy skin lesions on the toes. As the problem becomes more persistent the skin takes on a painful darker discolouration as the harmful toxins develop.
The most effective treatment of chilblains is avoiding them. Initially, wear good socks and shoes so that the feet do not get too cool. If the foot does become cold don't stick it in from of a heat source so that it gets warm too fast. The foot must be able to warm up slowly so the blood circulation has time to get used to the alterations in temperature. Once a chilblain does develop it needs to be protected so that it can heal up, particularly if the skin is damaged. Keep it covered to guard it from trauma from the footwear. Soothing chilblain creams can be used to promote the blood circulation and help remove the waste products that have built up in the skin which are creating the inflammation and irritation. Care should also be taken to prevent more chilblains developing, so the strategies that needs to be used to avoid them must be used even more. It is easy to get another one before the first one has healed up transforming this into a chronic problem. If the local measures to take care of the problem do not help, there are some medicines a doctor can suggest which you can use to open up the blood circulation. The drugs are not unique to the foot and work everywhere, so may be reserved for the more serious conditions. In the very worst chilblains, it is not unusual that they can be given advice to move and live in warmer climates.
