Chilblain or Perniosis is itchy and/or tender red or purple bumps that occur as a reaction to cold. The condition is also known as pernio and is a localised form of vasculitis. Chilblain is painful but they cause little or no permanent impairment. Chilblain is usually caused by an abnormal reaction of the body to the cold. People who have poor circulation, an inadequate diet, or an allergic response to low temperatures are vulnerable to chilblain. Chilblains may occur several hours after exposure to the cold in temperate humid climates. They are sometimes aggravated by sun exposure. Cold causes constriction of the small arteries and veins in the skin and re-warming results in leakage of blood into the tissues and swelling of the skin. Chilblain is less common in countries where the cold is more extreme because the air is drier and people have specially designed living conditions and clothing. Children and the elderly are most often affected. Chilblain is more likely to develop in those with poor peripheral circulation i.e. blue-red mottled skin on the limbs. If you think chilblain have occured, do not apply extreme heat or cold to the affected area. Contact your doctor immediately. Get the right footwear.
