Why are your hands and feet numb recently? Thank you for your questions.

The reason for numbness in hands and feet is firstly lack of rest, secondly lack of exercise, and finally weakness. As long as you work in an office, you will be prone to numbness. Because you always keep a posture, the blood circulation will not be too smooth, so you will be numb. The best solution is to take time to do more exercise and pay attention to diet, which may help you. Don't worry too much. Numbness of hands and feet is due to poor peripheral blood circulation and insufficient blood supply to hands and feet, which leads to numbness. Numbness of hands and feet is a common symptom in people's daily life, such as pregnancy, incorrect sleeping position, squatting in the toilet for a long time, etc., which are generally eliminated in a short time without any major problems. And some people's numbness in their hands and feet can't be relieved for a long time (more than one day), which may be a sign of physical illness. There are the following types of numbness in hands and feet caused by diseases: ★ There are generally four reasons for numbness in hands and feet: First, people with diabetes will have numbness in hands and feet. As long as numbness, soreness and swelling often occur in any part of the body, it is necessary to check blood sugar in time. The second is numbness caused by drugs or chemicals. If you have a cold or diarrhea, taking berberine or furazolidone will cause numbness in your hands and feet; Staying in an environment containing hydrogen, arsenic and carbon disulfide for a long time can also cause numbness in hands and feet. The third is numbness caused by neuritis. The most common symptoms of neuritis are numbness of hands and feet, muscular atrophy and weakness of limbs. If you have diarrhea or catch a cold for half a month, it will cause neuritis. Fourth, the limbs are scattered and numb. Numbness of limbs does not occur at the same time, but is scattered. This situation is that local nerves are stimulated, such as stroke coma after drunkenness, nerve stimulation of the head, nerve stimulation of the hands of the elderly with crutches, numbness of the upper limbs caused by cervical spondylosis, and numbness of the legs caused by waist and shoulder nerve stimulation. Numbness of hands and feet cannot be treated symptomatically, but the cause should be treated. No matter what causes numbness in hands and feet, you should first go to the hospital neurology department to check whether there is nerve damage and what kind of stimulation you have received. If it is a neurological problem, electromyography is needed to further confirm the degree, scope and nature of nerve injury. If the numbness of hands and feet is caused by other reasons, it will be transferred to other relevant departments for treatment. The numbness of hands and feet caused by nerve injury should be treated with drugs or surgery according to the degree, scope and nature of nerve injury. Drug therapy is usually combined with acupuncture and physical therapy to promote its rapid recovery. Surgical treatment is to open the compressed nerve by surgery to relieve the oppression and stimulation of the nerve. The degree of cure of the disease mainly depends on the etiology and nature of neuropathy. If it is peripheral nerve injury (except brain and spinal cord), it usually takes a long time to recover. The numbness of hands and feet in the elderly is closely related to cerebrovascular sclerosis, among which slight stroke and hypertension cause the most numbness. The so-called "small stroke" is also called "transient ischemic attack". Due to the ischemia of brain tissue, especially cerebral cortex, the sensory and motor centers of the brain appear dysfunction, leading to numbness of limbs in corresponding parts. Cerebral ischemia can cause numbness of one upper limb or lower limb, or hemiplegia, which usually lasts for several hours to several days. If not treated in time, it can develop into hemiplegia and even endanger life. "Small stroke" is accompanied by dizziness, headache and visual impairment (blurred vision or diplopia, etc. ), memory loss (especially recent memory loss), high or low blood pressure. Numbness of hands and feet is mostly unilateral, and numbness of thumb or forefinger is common. When blood pressure fluctuates or rises, systemic arterioles spasm and arterial lumen narrows, which can hinder colloidal blood circulation and lead to insufficient blood supply to hands and feet and numbness. In addition to numbness of hands and feet, the patient's limbs may feel stiff and ants walk, and often accompanied by dizziness, headache, dizziness, tinnitus, insomnia and other symptoms. In addition, blood pressure drops suddenly, and sometimes you may feel numb in your fingers. In spring, patients with hypertension are more prone to numbness of hands and feet, which is mostly related to the dry and cold climate in early spring, which is easy to cause sympathetic nerve excitement and systemic capillary contraction, thus causing blood pressure to rise. In addition to numbness of hands and feet, hypertension sometimes leads to transient cerebral ischemia to cerebral hemorrhage, which can seriously lead to facial distortion, paralysis, aphasia and coma, and even death. Cerebrovascular sclerosis is most common in people over 60 years old. Therefore, when the elderly have repeated numbness in their hands and feet recently, they should first consider cerebrovascular diseases. Because cerebrovascular diseases are often related to blood pressure, blood sugar and blood viscosity. In order to make a definite diagnosis, patients should go to the hospital to check their blood pressure, blood lipid, blood sugar, fundus and hemorheology, and cooperate with X-ray or CT examination when necessary. Once the primary disease is diagnosed, targeted treatment should be carried out, such as lowering blood pressure, thrombolysis, lipid and blood sugar. ★ Numbness of hands and feet may also be a problem of cervical vertebrae. If you often work at your desk or computer workers should consider whether you have cervical spondylosis, which will easily oppress your nerves, cause poor blood circulation, and lead to numbness of your hands and feet ■ Preventive measures for numbness of your hands and feet for office workers and computer workers ■ Neck and shoulder movements 1, clench your fingers behind your head, put your weight on your hands and arms, press your head down, straighten your neck, and take a deep breath for 5 times. 2.
