The coming of winter is dreaded by those who suffer from chilblains.
Chilblains, or perniosis, is one of those minor illnesses which are not regarded very seriously by doctors, but which can cause severe discomfort to the sufferer.
This condition is due to the action of cold, damp weather on skin which is particularly sensitive to its effects.
The superficial blood vessels in the skin appear to be over-sensitive to the cold. They dilate, and the blood does not flow fully through the tissues, which then suffer from lack of oxygen.
The skin develops blotchy red or bluish areas which thicken, and are usually intensely itchy.
They occur on the exposed parts of the body, such as the nose, the hands, the feet and lower legs.
The disorders of superficial circulation such as chilblains appear to be much more common in women than in men, but why they occur at all is not fully understood.
This may lead to secondary infection, and in treatment it may be necessary to use antibiotics both locally and generally.
In treatment, however, the most important element is to keep the affected part warm, and this can be done by the wearing of gloves, thick socks, stockings or boots.
The direct application of heat, such as exposing the part to an open fire or radiator, only makes the condition worse.
Drugs, unfortunately, are of limited use.
Calcium, either in tablet form or by injection, has long enjoyed a reputation as being useful in treating chilblains.
How it acts is not certain, although some people do obtain considerable relief.
