Causes Feet to Turn Blue?

Answer

Raynaud's disease is a disorder of the blood vessels. Blood vessels supplying blood to the skin become narrowed for those afflicted by the disease. This limits blood circulation to affected areas, which can include the feet. It makes the affected parts of the body feel numb and cool in cold temperatures and when stressed and can cause a blue appearance. There are two types of Raynaud's. When it occurs by itself, it is called primary Raynaud's. When it occurs with another disease, it is called secondary Raynaud's. Primary Raynauds is the most common form of the disease.
