Raynaud syndrome is Raynaud syndrome. Raynaud's syndrome refers to a group of syndromes in which fingers (toes) turn pale, purple and then red due to cold or emotional excitement. Most of them occur in 20 ~ 40 years old, and women are more than men. The onset is slow, winter begins, and the time is short. It can gradually attack when it is cold or emotional. Generally, both hands and fingers attack symmetrically, and toes can also occur.

Secondary Raynaud's syndrome is common in rheumatic immune diseases, such as systemic lupus erythematosus, rheumatoid arthritis, scleroderma, dermatomyositis/myositis and Sjogren's syndrome.
