Small red bumps occur on the fingers close to the tips and
fingernails and even on the toes.
These bumps are actually fluid, blood plasma,
that has seeped out of the cells into the surrounding
tissues.
When your hands get cold, the tiny blood vessels
constrict.
In your effort to warm your hands you may have
immersed them in warm water, or wrapped them around a
heater.
This action creates a sudden change in temperature,
causing a rapid increase of blood flow to the surface of the
skin.
The deeper blood vessels are not able to expand quick
enough to respond to this rapid increase in circulation,
causing the tiny capillaries to burst.
The fluid creates the
sore red bumps.
Chilblains are very common in countries in the northern
hemisphere, like Canada, England, Scotland, Ireland, France,
and other European countries, wherever there are cold, damp weather patterns.
In
the initial stages they are very sore to touch and very red.
As they start to heal they become quite itchy. Chilblains can
last up to four weeks.
You can have chilblains on your fingers or toes or both.
Symptoms are similar to Frostbite, but is not as severe or
damaging. |
