Chillblains – Definition, Causes, Diagnosis, Prevention and Treatment
Chilblains are also referred to as pernio or perniosis. They are small, itchy, painful swellings that generally appear on the skin after several hours of exposure to cold temperatures. Thus, they tend to develop during the winter months.
They are more likely to occur on the extremities such as the toes, fingers, nose and earlobes, which are the first areas to become cold. Other areas of the skin such as the heels, thighs and lower legs can also be affected in extreme temperatures.
A sudden increase in temperature and exposure to humidity increases the likelihood of chilblains developing. While one solitary chilblain may develop, often several will join together to form a larger, swollen red area of the skin. When the skin becomes cold, the tiny blood vessels beneath the skin narrow and constrict to prevent the loss of body heat through the skin. If the skin re-warms too quickly, there is some leakage of fluid from the blood vessels into the tissues. This causes areas of the skin to become inflamed and swollen, leading to chilblains.
