It’s that time of year when the weather turns cold that we see more of these on feet.
Some people are more prone to these than others and indeed suffer from them in milder conditions too.
The cause is blood moving away from the extremities towards the organs in the body as these are more important to keep at an ideal temperature.
If the chill remains for too long then blood vessels are damaged and less able to contract and expand.
If warming occurs too quickly, the sudden burst of blood can also damage vessels and feel painful.
Recommended are double layers of socks, (silk as a first layer to insulate then wool over the top). Plastizote insoles are helpful. Balmosa cream is good on skin which is not broken and can help keep the area warm. A good waterproof pair of shoes with thick soles is also a good idea if you are going to be outdoors.
