What is Acrocyanosis? - Information about Causes and Symptoms

You have the condition known as acrocyanosis if your extremities, that is, your fingers, toes, wrists or ankles, sometimes look blue. The bluish tinge comes from the sudden contraction of tiny arteries that supply blood to your hands and feet. Because of such spasms, these parts get less blood than they need, and waste products build up in local veins. This gives the skin its abnormal color. No body knows why acrocyanosis develops. The condition is intensified by cold. It is present to an equal degree in both hands or both feet. It is not painful, but the affected parts nearly always feel cold and may be sweaty. Acrocyanosis does not cause ulceration or other skin problems.

What should be done?

Do not be too concerned if you have acrocyanosis. It is fairly common, especially among women. It is not a sign of a major disorder, and it does not need or respond to treatment. All you can do about it is protect your hands and feet from extreme cold.
