Raynaud's disease causes some areas of the body to feel numb or cold. These feelings often occur during the cold season or in times of stress, and the disease affects women more than men, reports Mayo Clinic. In a person suffering from Raynaud's disease, narrowing arteries cause a decrease in blood flow. Symptoms of this disease are cold fingers and toes that turn white, and numbness that is sometimes painful. Symptoms and the duration of these feelings can vary.
There are two types of Raynaud's disease: primary and secondary. Some causes of secondary Raynaud's disease are connective tissue diseases, injuries and certain medications. There is a link between beta blockers and some migraine medications and this disease, notes Mayo Clinic. There is also a link between Raynaud's disease and some cold medications that cause blood vessels to narrow. Risk factors for Raynaud's disease include sex, age and family history. Although severe Raynaud's disease is very rare, it can cause permanent damage to fingers and toes due to lack of blood circulation.Learn more about Conditions & Diseases
