It most often begins in women younger than age 30. Secondary Raynaud phenomenon is when the condition is linked to other conditions and can occur at any age.</p><p>Common causes of secondary Raynaud phenomenon are:</p><ul><li>Diseases of the arteries (such as <a test="test" href="./000171.htm">atherosclerosis</a> and <a test="test" href="./000172.htm">Buerger disease</a>)</li><li>Drugs that cause narrowing of arteries (such as amphetamines, certain types of beta-blockers, some cancer drugs, certain drugs used for migraine headaches)</li><li>Arthritis and autoimmune conditions (such as <a test="test" href="./000429.htm">scleroderma</a>, <a test="test" href="./000456.htm">Sjögren syndrome</a>, <a test="test" href="./000431.htm">rheumatoid arthritis</a>, and <a test="test" href="./000435.htm">systemic lupus erythematosus</a>)</li><li>Certain blood disorders, such as cold agglutinin disease or cryoglobulinemia<br/></li><li>Repeated injury or usage such as from heavy use of hand tools or vibrating machines</li><li>Smoking</li><li><a test="test" href="./000057.htm">Frostbite</a></li><li><a test="test" href="./001434.htm">Thoracic outlet syndrome</a></li></ul></div></div></section><section><div class="section"><div class="section-header"><div class="section-title"><h2>Symptoms</h2></div><div class="section-button"><button type="submit" aria-controls="section-2" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">

Most people do not have much pain. The skin of the arms or legs may develop bluish blotches which goes away when the skin is warmed up.</p><p>People with secondary Raynaud phenomenon are more likely to have pain or tingling in the fingers.

Wear mittens or gloves outdoors and when handling ice or frozen food. Avoid getting chilled, which may happen after any active recreational sport.</li><li>Stop smoking. Smoking causes blood vessels to narrow even more.</li><li>Avoid caffeine.</li><li>Avoid taking medicines that cause blood vessels to tighten or spasm.</li><li>Wear comfortable, roomy shoes and wool socks. When outside, always wear shoes.</li></ul><p>Your provider may prescribe medicines to dilate the walls of the blood vessels. These include topical nitroglycerin cream that you rub on your skin, calcium channel blockers, sildenafil (Revatio), and tadalafil (Adcirca).</p><p>Low dose aspirin is often used to prevent blood clots.</p><p>For severe disease (such as when gangrene begins in fingers or toes), intravenous medicines may be used. Surgery may also be done to cut nerves that cause spasm in the blood vessels. People are most often hospitalized when the condition is this serious.</p><p>It is vital to treat the condition causing Raynaud phenomenon.</p></div></div></section><section><div class="section"><div class="section-header"><div class="section-title"><h2>Outlook (Prognosis)</h2></div><div class="section-button"><button type="submit" aria-controls="section-5" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">
