Raynaud disease and phenomenon are problems with the blood vessels. It causes blood flow problems to the fingers ears, nose, and lips.
Raynaud disease (primary Raynaud) is the most common form. There are no other associated medical conditions.
Raynaud phenomenon (secondary Raynaud) is the more severe form. It occurs along with other medical conditions such as:
Blood vessels normally narrow in response to cold temperatures or emotional stress. Raynaud 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 Raynaud is believed to be caused by the associated disease.
Raynaud is more common in females and those aged 15-40 years old. Factors that may increase your chance of Raynaud include:
An attack of Raynaud 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:
You will be asked about your symptoms and medical history. A physical exam will be done. Tests may include:
There are several ways to reduce the symptoms of Raynaud during an attack:
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:
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.
There are no current guidelines for preventing Primary or Secondary Raynaud. To help prevent Raynaud symptoms:
