When Raynaud phenomenon is a primary condition, meaning it occurs by itself and not in association with other diseases, it is referred to as Raynaud disease.

Common causes of secondary Raynaud phenomenon are:

Exposure to the cold or strong emotions bring on the changes.

People with Raynaud disease have problems in the same fingers on both sides. 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.

People with secondary Raynaud phenomenon are more likely to have pain or tingling in the fingers. Painful ulcers may form on the affected fingers if the attacks are severe.

Your health care provider can often discover the condition causing Raynaud phenomenon by asking you questions and doing a physical exam.

Taking these steps may help control Raynaud phenomenon:

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).

Low dose aspirin is often used to prevent blood clots.

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.
