The whitening of the ends of the fingers in the cold is considered to be Raynaud’s syndrome, and prompt medical attention should be paid to keep the limbs warm, quit smoking or oral calcium antagonists such as nifedipine tablets and α-receptor antagonists such as perphenazine and other medications.
Raynaud’s syndrome is a syndrome of episodic pallor and purpling followed by flushing of the fingers or toes due to cold and emotional stress. It can be categorized into idiopathic and secondary Raynaud’s syndrome.
Idiopathic Raynaud’s syndrome may be related to cold stimulation, emotional excitement, long-term vibratory mechanical work and other factors; secondary Raynaud’s syndrome is often accompanied by systemic scleroderma, systemic lupus erythematosus, dermatomyositis and other diseases.
Patients with Raynaud’s syndrome should avoid working at low temperatures, keep the distal extremities warm, avoid emotional fluctuations, quit smoking; oral calcium antagonists, such as nifedipine tablets, diltiazem hydrochloride, etc.; oral α-receptor antagonists, such as prazosin, etc.; sympathetic neurectomy can be considered for those who do not respond to the drugs.
When the end of the finger is cold and white, it is recommended to consult a doctor to further clarify the diagnosis, and use medication under the guidance of the physician, so as not to delay the condition.
