Chilblains can be a common problem on the feet in colder climates. They are virtually unknown in hotter environments. They are a painful response of the circulation in the toes after a foot is cold and is heated up too fast. Because of this problem with the blood circulation not reacting, there's an inflamation related response leading to small red-colored and itchy skin lesions on the toes. As the problem becomes more persistent the skin takes on a painful darker discolouration as the waste products accumulate.
The most effective management of chilblains is prevention. Firstly, wear good socks and shoes so that the feet do not get too cold. In the event that the foot does get cold don't stick it in from of the heat source so that it gets warm too fast. The foot should be allowed to warm up slowly so the circulation has time to get used to the alterations in temperature. Once a chilblain does develop it should be protected in order that it can heal up, especially if the skin is broken. Keep it covered to guard it from damage from the shoe. Soothing chilblain creams can be used to stimulate the blood circulation and help get rid of the harmful toxins which have built up in the skin that are creating the inflammation and irritation. Care should also be taken to prevent more chilblains developing, so the strategies that ought to be used to prevent them must be used even more. You can easily get another one before the first one has healed up converting this into a chronic problem. If the local measures to look after the problem don't help, there are some medicines a doctor may suggest that can be used to open up the blood circulation. The drugs are not unique to the foot and work everywhere, so may be reserved for the more severe cases. In the very most severe cases, it is not uncommon that they be given suggestion to relocate and live in warmer environments.
