Ms. Li is a citizen of Nanjing. Her hands and feet are cold easily, and she often gets frostbite in winter. After this examination in the hospital, it was found that her blood picture was abnormal and she was diagnosed as systemic lupus erythematosus. ? After getting up in the morning, ten fingers will turn white, shriveled and painful, just like the pain of needles, and then turn purple instantly. I really don't think this is a disease. Originally, her hands would get frostbite, which was considered as a cold. The doctor said that Ms. Li's fingers would turn white and purple after catching a cold. This is a typical Raynaud's syndrome.

Raynaud's syndrome is caused by peripheral small vessel ischemia and microcirculation disturbance. After cold or emotional excitement, the skin color usually turns white suddenly from the fingertips, then turns purple, and gradually spreads to the whole finger and palm, accompanied by local cooling, numbness and hypoesthesia. After a few minutes, the skin will become ruddy, warm and burning. Compared with common frostbite, the symptoms are more serious. The fingers around will turn white and purple, which will be aggravated in winter, because the ambient temperature is low and there is little blood supply around. This is different from the cold on our ordinary hands. It is difficult for her to recover from a cold.

Raynaud's disease is a treatable manifestation of rheumatic immune disease. It can only control symptoms and alleviate the development of the disease. Pay attention to the exposure of distal limbs to cold environment, avoid contact with cold water, and keep limbs warm. Eat less spicy food and keep a good mood. Severe cases can be treated with traditional Chinese medicine. Drink more water and eat more fresh fruits and vegetables to increase metabolism and immunity. Raynaud's syndrome is usually incurable, but after active and reasonable treatment, the prognosis is relatively good. About 15% patients can be relieved naturally, and 30% patients can get worse gradually. Long-term persistent arterial spasm can lead to irreversible arterial organic stenosis, but it rarely needs to be controlled.

Raynaud's syndrome mainly includes primary and secondary, and its treatment should depend on the condition. Mild Raynaud phenomenon can only be controlled by keeping warm, preventing freezing, avoiding skin damage, mental stress and overwork, and patients must quit smoking. For recurrent attacks or severe symptoms, calcium antagonists can be added.
