Typical symptoms of Raynaud’s disease are regular and recurring episodes of pallor, bruising and flushing of the skin at the ends of the fingers when the organism is exposed to stimuli such as emotional changes or cold. Raynaud’s disease usually occurs in young adult females and is commonly found on the fingers, occasionally involving the toes, cheeks and outer ears, usually on both sides. The pallor occurs because of intense spasm of the small arteries of the skin, resulting in a temporary cessation of capillary perfusion. Bruising may occur because of tissue hypoxia and accumulation of metabolic products, which cause dilatation of the capillaries and small veins. Although the spasm of the small arteries will be slightly relieved, there will still be a small amount of blood flowing into the capillaries, which will remain in a state of hypoxia. Flushing may be a temporary increase in the amount of blood flowing into the capillaries, resulting in reactive congestion. If the above symptoms occur, it should be taken seriously, and it is recommended to go to the hospital in time and follow the doctor’s instructions to standardize the treatment.
