Site Index Search this site: Disease of the Month Raynaud's Phenomenon Definition Spasm of fingers during a Raynaud's attack Raynaud's phenomenon (RP) is a condition resulting in discoloration of the fingers and/or the toes when the patient is exposed to changes in temperature (cold or hot) or emotional events. Skin discoloration occurs because an abnormal spasm of the blood vessels results in a diminished blood supply. Initially, the digit(s) involved turn white because of diminished blood supply. The digit(s) then turn blue because of prolonged lack of oxygen. Finally, the blood vessels reopen, causing a local "flushing" phenomenon, which turns the digit(s) red. This three-phase color sequence (white to blue to red), most often upon exposure to cold temperature, is characteristic of RP. What Causes Raynaud's? Doctors aren't sure exactly what causes Raynaud's phenomenon. They do know, however, that episodes are often triggered by cold temperatures and sometimes by emotional stress, such as nervousness or excitement. There are many causes of secondary Raynaud's phenomenon (when Raynaud's accompanies other diseases), including use of some hand-held vibrating tools, inflammation of blood vessels (called vasculitis) or blockage of blood vessels. Symptoms of Raynaud's Symptoms of RP depend on the severity, frequency, and duration of the blood vessel spasm. Most patients with mild disease only notice skin discoloration upon cold exposure. They may also experience mild tingling and numbness of the involved digit(s) that will disappear once the color returns to normal. When the blood vessel spasms become more sustained, the sensory nerves become irritated by the lack of oxygen, and can cause pain in the involved digit(s). Rarely, poor oxygen supply to the tissue can cause the tips of the digits to ulcerate. Ulcerated digits can become infected. With continued lack of oxygen, gangrene of the digits can occur.

The internet is a big place. There is a lot of information out there. Some are very, very good, and some are very, very bad. On this and the linked categorized pages are some web sites we have found useful. Raynauds (ray-NODES) phenomenon is a condition in which poor blood flow results in discomfort and skin color changes in affected parts of the body. The parts of the body most commonly affects include the fingers and toes, but the ears, nose, nipples and knees can also be involved. This condition can begin at any age, but usually begins between ages 15 and 40.

Treatment Raynaud's Vascular Disorder Definition Episodes of vasospasm (constriction of small arteries) of the digits. It is characterized by digital blanching, cyanosis (blue), a feeling of numbness or dulled sensory response and rubor (red) after cold exposure and rewarming. It can also be induced by anxiety or stress. This condition is primarily confined to the fingers and toes but can affect areas of the body such as your nose, cheeks, ears and even tongue. Stages of Raynauds Blanching (digits turn white) represents the ischemic (lack of adequate blood flow) phase of the phenomenon, caused by digital artery vasospasm. Cyanosis (digits turn blue) results from deoxygenated blood in capillaries and small veins. Hyperemic phase (digits regain coloring, looking flushed) upon rewarming and resolution of the digital vasospasm, the digits may appear red. Raynaud's can be a primary or secondary disorder Primary Raynaud's phenomenon is also called Raynaud's disease. Criteria for Raynaud's disease include episodic digital ischemia (sequence of color changes in the skin in response to cold or stress), a numb, prickly feeling or stinging pain upon warming or relief of stress, absence of arterial occlusion, bilateral distribution, absence of symptoms or signs of other diseases that also cause Raynaud's phenomenon, and duration of symptoms for 2 years or longer. Most people with Raynaud's disease develop symptoms before they reach 40 years of age. It can occur in young children. Raynaud's disease affects women three to five times more frequently than men. The prevalence is lower in warm climates than in cold climates.

Back to Top General Raynaud's Disease Information Raynaud’s disease and Raynaud’s phenomenon are circulatory disorders that cause the fingers, toes and other extremities to be overly sensitive to cold. When the extremities are exposed to cold temperatures, the blood vessels constrict and go into spasm, resulting in a characteristic white, then blue, then red color sequence as the digits lose, then regain, circulation of oxygenated blood. Over time, the affected areas can begin to shrink in size and ulcers may form. In severe cases, gangrene can form from ongoing contraction of the arteries. Raynaud’s disease is three to five times more common in women than men and is most often found in colder climates. Back to Top Possible Causes of Raynaud's Disease The cause of Raynaud’s disease is unknown, but experts think the blood vessels in Raynaud’s sufferers over-react to the sensation of cold. Attacks can be provoked by exposure to winter wind and temperatures, but they can also be instigated by reaching into a cold freezer or holding hands under cold water. For some people, anxiety and stress can bring on an attack without exposure to cold. Reynaud’s phenomenon differs from Reynaud’s disease in that the cause of the disorder comes from underlying conditions, like lupus, scleroderma, rheumatoid arthritis, carpal tunnel syndrome, smoking, injuries and certain medications.

Migraine Headaches, Raynauds Disease or Raynaud's Syndrome are how some respond to stress, i.e. vascular constrictions of the extremities. Raynaud's Phenomenon is named for the man who identified the condition. Specific relaxation techniques improve the chances of those suffering from migraine headaches and Raynaud's Syndrome to reduce and sometimes eliminate the symptoms. Migraine Headaches can be brought on by any number of stressors, i.e., allergy to peanuts, catsup, chocolate, hard liquor, and so on.

Glossary Raynaud's Disease - Cold, Numb, Foot Pain Definition Episodic vasospasm (constriction of small arteries) of the digits.

It can also be induced by anxiety or stress. This condition is primarily confined to the fingers and toes but can affect areas of the body such as your nose, cheeks, ears and even tongue. Primary Raynaud's phenomenon is also called Raynaud's disease. Criteria for Raynaud's disease include episodic digital ischemia (sequence of color changes in the skin in response to cold or stress), a numb, prickly feeling or stinging pain upon warming or relief of stress, absence of arterial occlusion, bilateral distribution, absence of symptoms or signs of other diseases that also cause Raynaud's phenomenon, and duration of symptoms for 2 years or longer. Most people with Raynaud's disease develop symptoms before they reach 40 years of age. It can occur in young children. Raynaud's disease affects women three to five times more frequently than men. The prevalence is lower in warm climates than in cold climates. Etiology The mechanisms postulated to cause Raynaud's phenomenon include increased sympathetic nervous system activity, heightened digital vascular reactivity to vasoconstrictive stimuli, circulating vasoactive hormones, and decreased intravascular pressure. The sympathetic nervous system mediates the digital vasoconstrictive response to cold exposure and emotional stress but has been discounted as a primary mechanism. Some investigators have suggested that increased sensitivity, increased numbers of postsynaptic alpha2-adrenergic receptors, or both enhance the vasoconstrictive reactivity to sympathetic stimulation. In some cases of Raynaud's phenomenon, endogenous vasoactive substances (e.g., angiotensin II, serotonin, and thromboxane A2) and exogenous vasoconstrictors (e.g., ergot alkaloids and sympathomimetic drugs) may cause digital vasospasm. Many patients with Raynaud's phenomenon have hyperhidrosis (sweaty palms).

Raynaud's Phenomenon is a Disorder of the small blood vessels that feed the skin. During an attack of Raynaud's, these arteries contract briefly, limiting blood flow. This is called a vasospasm. Deprived of the blood's oxygen, the skin first turns white then blue. The skin turns red as the arteries relax and blood flows again. Extremitieshands and feetare most commonly affected, but Raynaud's can attack other areas such as the nose and ears. What are the symptoms? Symptoms include changes in skin color (white to blue to red) and skin temperature (the affected area feels cooler). Usually there is no pain, but it is common for the affected area to feel numb or prickly, as if it has fallen asleep. What causes Raynaud's?
