Do you suffer in the cold where your extremities are affected, well you may have chilblains? If you would like to find out more, please read on.
What are chilblains?
Chilblains are where your blood vessels in the skin constrict forming a painful reddish, bluish lesion on the skin.
Chilblains occur mainly in fingers, toes, ears, and face. Chilblains commonly develop in people with poor circulation and those exposed to colder climates. Those at a higher risk of developing chilblains are younger girls, older ladies, individuals with a lower body mass index and smokers.
What do chilblains look like?
As mentioned earlier, chilblains mainly look like tiny itchy/painful red/blue areas of skin that are commonly found on fingers, toes, ears, and face. During sudden cold spells chilblains occur, whose initial symptoms are burning and itching, and this can intensify when the areas are warmed up. In some more severe cases the chilblain may break the skin down and become an ulcer and this can further develop into infection as there is a break in the skin barrier and healing is slower due the vasospasm of the blood vessels.
How can I prevent chilblains from occurring?
This can be achieved best by following the advice below. Keeping your feet warm in a normal way is essential in the prevention.
- Leg warmers, woollen socks, sheepskin slippers should be used.
- Feet should not be placed in front of a heat source when they are cold
- Feet should not be exposed to direct heat such as heaters, fires, and hot water bottles.
- Cessation of smoking as this reduces peripheral circulation by making the blood thicker and restricting the blood flow and less oxygen reaching the tissues.
