It will usually disappear within a short time and will not cause any serious problems. question. However, if some people experience numbness in their hands and feet that cannot be relieved for a long time (more than a day), it may be a sign of disease in the body.

[Edit this paragraph]

★The causes of numbness of hands and feet generally include the following four aspects:

[Edit this paragraph] p>

First, people with diabetes may experience numbness in their hands and feet. Whenever numbness, soreness, or swelling occurs frequently in any part of the body, it is necessary to check blood sugar in time.

The second is numbness caused by drugs or chemical agents. For example, when you have a cold or have diarrhea, taking berberine or furosemide will cause numbness in your hands and feet. Being in an environment containing hydrogen, arsenic, carbon disulfide, etc. for a long time will also cause numbness in your hands and feet.

The third is numbness caused by neuritis. The most common symptoms of neuritis are numbness of the hands and feet, muscle atrophy, and weakness of the limbs. If you have diarrhea or a cold for half a month, it can cause neuritis.

Fourth is scattered numbness in the limbs. Numbness in the limbs does not occur at the same time, but occurs dispersedly. In this case, the local nerves are stimulated, such as stroke after drunkenness, stimulation of the nerves in the head caused by coma, stimulation of the nerves in the hand of the elderly using a cane, and numbness of the upper limbs caused by cervical spondylosis. , leg numbness caused by lumbar shoulder nerve stimulation, etc.

Numbness of hands and feet cannot be treated symptomatically, but the cause must be treated. Regardless of the cause of numbness in your hands and feet, you should first go to the neurology department of the hospital for an examination to determine whether the nerves are damaged and what kind of stimulation they have received.

If it is a neurological problem, electromyography is also required to further confirm the degree, scope, nature, etc. of the nerve damage. If the numbness of the hands and feet is caused by other reasons, please refer to other related departments for treatment.

For numbness of hands and feet caused by nerve damage, the choice of drug treatment or surgery should be based on the degree, scope, and nature of the nerve damage. Drug treatment is usually combined with acupuncture and physical therapy to promote rapid recovery. Surgical treatment is to divert the compressed nerves through surgery to relieve nerve compression and stimulation.

The degree of cure depends mainly on the cause and nature of the neuropathy. If it is a peripheral nerve injury (nerves other than the brain and spinal cord), the recovery time is generally longer.

★ Numbness in the hands and feet of the elderly is often closely related to cerebrovascular sclerosis, among which minor stroke and high blood pressure are the most common causes of numbness.

The so-called "mini-stroke" is also called "transient ischemic attack". Due to ischemia of brain tissue, especially the cerebral cortex, functional disorders occur in the sensory and motor centers of the brain, resulting in numbness of the corresponding limbs. Cerebral ischemia can cause numbness in one upper or lower limb, or half of the body, which usually lasts from a few hours to a few days. If not treated in time, it can develop into hemiplegia and even be life-threatening.

In addition to numbness or weakness in the hands and feet, "mini-stroke" is also accompanied by dizziness, headache, visual impairment (blurred vision or double vision, etc.), memory loss (especially recent memory loss), and Symptoms such as increased or low blood pressure; numbness of hands and feet mostly on one side, with numbness of the thumb or index finger being the most common.

When the blood pressure of hypertensive patients fluctuates or rises, small arteries throughout the body spasm and the arterial lumen narrows, which can cause colloid blood circulation disorders, causing insufficient blood supply to the hands and feet and causing numbness. In addition to numbness in the hands and feet, patients may have stiffness and ant-like sensation in their limbs, and are often accompanied by symptoms such as dizziness, headache, vertigo, tinnitus, and insomnia. In addition, a sudden drop in blood pressure may sometimes cause numbness in the fingers.

In spring, patients with high blood pressure are more likely to experience numbness in their hands and feet. This is mostly related to the dry and cold climate in early spring, which can easily cause sympathetic nerve excitement and constriction of capillaries throughout the body, thus causing an increase in blood pressure. In addition to numbness in the hands and feet, high blood pressure may sometimes cause transient cerebral ischemia to cerebral hemorrhage, causing distortion of the mouth and eyes, paralysis, aphasia, coma, etc., and even death.

Cerebrovascular sclerosis is most common in people over 60 years old. Therefore, if the elderly have recurring numbness in their hands and feet recently, they should first consider a cerebrovascular disease.

Cerebrovascular diseases are often related to blood pressure, blood sugar, blood viscosity, etc.

In order to confirm the diagnosis, patients should go to the hospital for blood pressure, blood lipids, blood sugar, fundus and hemorrheology examinations. If necessary, they should cooperate with X-ray or CT examinations. Once the primary disease is diagnosed, targeted treatment should be carried out, such as lowering blood pressure, thrombolysis, lowering blood lipids, lowering blood sugar, etc.

·Not caused by disease Reasons for numbness in hands and feet:

[Edit this paragraph]

☆ Traditional Chinese medicine believes that people have seven emotions and six desires. The seven emotions are: joy, anger, sadness, thought, grief, fear, and surprise. The key points are:

Happiness and sadness,

Sadness and anger hurt the liver,

Thoughts hurt the spleen,

Sadness hurts the lungs ,

Fear and fear of kidney damage.

If these items are too strong, they will harm the body.

After prolonged crying, the liver and lungs will be "shocked". Since the liver governs blood, anger will damage the liver. If the blood bank oscillates, the blood vessels will be disordered. The lungs govern qi. When they are "injured", it will cause poor blood circulation, temporary "failure" of the respiratory system, and numbness in the hands and feet. , weakness, uncontrollable facial twitching, dizziness, chest tightness, breathlessness, and other symptoms.

This is a mechanical problem of the body's internal organs, not a neurological problem. The way to solve the problem is to control your emotions and don't cry or be sad. If you cry after crying, drink more water or take a nap to relieve the pain.

☆ Numbness in the hands and feet can also be caused by insufficient Qi and blood, which is called blood deficiency. Because the Yang Qi is weak, it causes blood deficiency, and the Yang Qi is unable to circulate blood, and the blood cannot reach the ends of the blood vessels. The hands and feet are the extremities of the human body, so blood deficiency will cause numbness.

Pay attention to daily maintenance. If you have Yang deficiency, you should eat less cold food.
