What are Chilblains?
Chilblains are red bumps which appear on the skin following sudden changes in temperature. The blood vessels which supply the toes are some of the smallest in the body In cold conditions these blood vessels constrict and become even smaller, however if the vessels are made to dilate rapidly as the result of a change in temperature small amounts of blood are thought to leak out of the vessel producing the painful swellings in the skin.
