Chillblains can be due to the result of an abnormal vascular reaction to cold. They can occur at any age.

Causes

The most common cause is re-warming the feet too quickly, which can cause a rapid dilation of small blood vessels.

Symptoms

• Itchiness
• Redness
• Swelling

Chillblains will usually subside within 2-3 weeks, at times they can be severe and break the skin which can lead to ulcerations.

Prevention

• Keep the feet warm during winter months
• Avoid sudden changes from hot to cold or cold to hot.
• Gentle foot exercises to promote blood flow.
• Wear warm socks to bed- preferably natural fibres, bamboo, cotton or wool.
