When the weather is cold, my fingers will become white and stiff. What kind of disease is this?

1, which may be Raynaud's syndrome. After washing your hands with cold water or getting emotional, your finger skin suddenly turns pale and then turns purple. The attack usually starts from the fingertips, and the fingers are often numb, acupuncture and hypoesthesia. After a few minutes, it gradually turns red and the skin becomes warm and hot. Finally, the skin color returned to normal. This could be Raynaud's syndrome. Common causes are: cold stimulation, nervous excitement, endocrine disorders; The incidence of Raynaud's syndrome may eventually be as high as 50%. There are also genetic factors, and blood viscosity often rises.

2. Pay attention to cold and warmth, relieve patients' mental worries, avoid the influence of emotional factors and avoid smoking. Cold is the most important inducing factor. The disease is recessive, but it may also happen suddenly. Generally speaking, return to a warm environment, or soak the affected part in warm water or rub it, and wave the limbs of the affected part to prevent it from continuing to attack. Pay attention to keep warm at ordinary times. Fingers turning cold and white is a normal reaction of human body. Usually, the blood vessels of the hand will cool and contract to reduce the spread of body heat. Warm-up expansion and red hands help the body to dissipate heat.

3. Raynaud's syndrome refers to the paroxysmal spasm of arterioles at the end of fingers (toes) under the stimulation of cold or mental stress, which leads to ischemia of fingers (toes), pallor, cyanosis and flushing of limbs, accompanied by tingling and numbness. Cold weather easily chills the limbs, so it is easy to be ignored. However, if there is long-term ischemia, the limbs will form ulcers, the finger pads will disappear, scabbed skin will form or calcify, and finally turn from white to purple, and finally turn black. At this point, the limbs are ischemic and necrotic and must be amputated.

4. Patients with Raynaud's syndrome will suffer from fingertip ulcer and gangrene if they don't seek medical treatment in time. What's more, they are in danger of amputation. If they can see a doctor in time when Raynaud's syndrome occurs, they can usually screen as early as possible, find these primary diseases and intervene in advance, which can achieve better treatment results. Actively cooperate with the doctor, don't worry too much. Keep a good attitude, pay more attention to the doctor's guidance and keep a happy mood. If medical treatment fails, surgical treatment can be considered.
