Chilblains are a curse of winter for many people and especially if you spend time outdoors hiking, trail running, climbing, skiing or wild swimming. Also known as pernio or perniosis, the condition causes small patches of inflamed and itchy skin.
Chilblains usually develop on fingers and toes, although they can appear on legs, ears or nose, and the often occur after exposure to air that's cold or damp, but not freezing.
