Whether Raynaud’s syndrome is difficult to treat cannot be generalized. Raynaud’s syndrome is divided into primary Raynaud’s syndrome and secondary Raynaud’s syndrome. There is no cure for Raynaud’s syndrome at present, but the condition can be controlled through standardized treatment. 1. Primary Raynaud’s syndrome may be related to the environment, endocrine disorders, heredity, infections and so on. Secondary Raynaud’s syndrome may be related to systemic scleroderma, systemic lupus erythematosus, rheumatoid arthritis and primary pulmonary hypertension. 2. Raynaud’s syndrome mainly manifests as cold hands and feet, numbness, white and purple fingers, which may cause slow growth, roughness and deformation of nails in the later stage. 3. Clinical treatment of Raynaud’s syndrome can be given to calcium antagonists such as nifedipine, thiazolidone and α-receptor antagonists such as prazosin, doxazosin and other drugs symptomatic treatment. Secondary Raynaud’s syndrome also requires immunomodulatory therapy to address the cause. Patients with Raynaud’s syndrome are advised to consult a rheumatologist in a timely manner and follow the doctor’s instructions.
