Raynauds disease and phenomenon are problems with the blood vessels. It causes blood flow problems to the fingers ears, nose, and lips.

Raynauds disease (primary Raynauds) is the most common form. There are no other associated medical conditions.
Raynauds phenomenon (secondary Raynauds) is the more severe form. It occurs along with other medical conditions such as: SclerodermaSystemic lupus erythematosusRheumatoid arthritisSjogren's syndromeCarpal tunnel syndrome
Blood vessels normally narrow in response to cold temperatures or emotional stress. Raynauds is an exaggerated response to these triggers. The narrow blood vessels make it difficult to get enough blood flow to certain areas of the body. Fingers are affected most often.
It is not known what causes this abnormal reaction, but it is probably related to a problem of the nervous system. Secondary Raynauds is believed to be caused by the associated disease.
Raynauds is more common in females and those aged 15-40 years old. Factors that may increase your chance of Raynauds include:
Activities that involve repeated stress to hands such as:
TypingPlaying pianoRegular operation of vibrating tools, as in constructionExposure to certain chemicalsA connective tissue disease (such as scleroderma)
Diseases of the arteries, including
Injuries to the hands or feet, such as wrist fractures or
Certain medications, such as:
chemotherapyCold remediesMigraine medications containing ergotamineEstrogen-containing medications
An attack of Raynauds may last a few minutes to a few hours. It usually comes on in response to the cold or during emotional distress. During an attack, symptoms may include:
Skin discoloration–color may change to white, blue, and red White occurs when the arteries narrow or collapseBlue appears when the fingers, toes, or other areas are not getting enough oxygen-rich bloodThe skin turns red and may become swollen when the attack subsides and blood returnsThrobbing and tingling sensations, stinging, pain, and swelling of the affected area. This may occur at the end of the attack as blood flow returns to the area.
The doctor will ask about your symptoms and medical history. A physical exam will be done. Tests may include: Nailfold capillaroscopy—study of the capillaries under a microscope
Blood tests—to help distinguish between Primary and Secondary Raynauds, and help identify underlying autoimmune conditions:
Complete blood countAntinuclear antibody
Erythrocyte sedimentation rate
There are several ways to reduce the symptoms of Raynauds during an attack:
Run warm (not hot) water over fingers and toes as quickly as possible. However, do not place anything hot on your skin, as it may cause damage.If you are outside, move inside.Place your hands on a warm area of the body, such as under your armpits or on the abdomen.
Try to stimulate blood circulation by wiggling your fingers and toes. Make wide circles with your arms.
When the above measures fail, medications may help relieve symptoms. Medications that can affect blood vessel size include: Calcium channel blockersAlpha-blockersVasodilators
Rarely, surgery may be done when symptoms are persistent and debilitating. This involves cutting the sympathetic nerves that supply the affected fingers. These nerves control the expansion and narrowing of blood vessels.
Chemicals may be injected into the nerve that is responsible for the narrowed blood vessel. The chemical stops the nerve.
Treating the underlying disorder will help manage the symptoms of Secondary Raynauds.
There are no current guidelines for preventing Primary or Secondary Raynauds. To help prevent Raynauds symptoms: Stay warm. Avoid cold temperatures when possible.Dress in layers.Wear clothing that covers extremities such as hats, gloves, or socks.Learn to adapt to stressful situations.
Don't smoke. If you smoke, talk to your doctor about how to successfully
training to control body temperature.
Avoid the use of medications known to exacerbate Raynaud’s.
To minimize the risk of complications from Raynauds: Keep skin on fingers and toes protected.Avoid injuries.
