Raynaud’s syndrome is clinically manifested by intermittent changes in skin color, pallor, cyanosis, and flushing of the skin of the fingers (toes) in response to irritation, accompanied by pain or tightness. In early patients, symptoms are mild and nonspecific. Raynaud’s syndrome is essentially a transitory response of the peripheral blood vessels of the extremities to hypothermia or emotional stress. Raynaud’s syndrome is most common in young adult women, has a familial tendency, and is more common in colder regions and during the winter and spring months. Raynaud’s syndrome most often involves the hands, when the fingers (or toes) in the cold or emotional changes and other stimuli limb skin in turn after the skin pale, cyanosis and redness “three-phase” color changes or from pale to cyanosis and cyanosis to redness “biphasic” color changes. Early presentations may be atypical and the diagnosis may be missed. Mild Raynaud’s syndrome may be associated with pins and needles, numbness and/or clumsiness in the extremities, and finger pain, and in severe cases, ulcers on the tips of the fingers and toes. Current treatments include general therapy, medications, surgery other treatments to improve the patient’s quality of survival and slow the progression of ischemic tissue damage. It is recommended that patients with Raynaud’s syndrome go to the hospital in time and follow the doctor’s instructions for standardized treatment to avoid delays.
