Numbness in hands and feet

If numbness occurs in your hands and feet, and the degree of numbness is too severe, it will directly affect the normal activities of the body. There are many reasons for numbness in the hands and feet, such as pressure, diabetes, cold, neuritis, etc. If this happens occasionally, you can ignore it, but if it happens frequently, you should see a doctor to find out the cause.

Why are my hands and feet numb?

Numbness in the hands and feet is caused by poor peripheral blood circulation. Numbness occurs due to insufficient local blood supply to the hands and feet. Numbness in the hands and feet is a symptom that people often experience in their daily lives. It can be caused by pregnancy, incorrect sleeping posture, and squatting on the toilet for a long time. It will usually disappear in a short time and there will be no big problem. However, for some people, if the numbness in their hands and feet does not subside for a long time (more than a day), it may be a sign of illness in the body.

Numbness in the hands and feet is actually called arthralgia in the field of traditional Chinese medicine. It is an important signal that wind, cold, dampness, and evil toxins have invaded the body. Before the evil poisonous gas invades the internal organs, the first feeling is numbness in the hands and feet, soreness, heaviness, pain and tingling in the limbs. This is the signal sent by the obstruction of the meridians and is also the last line of defense of the human body. If not treated in time, the meridians will be damaged, thus destroying the human body's nerve conduction function system, causing nerve necrosis, and eventually leading to stroke, hemiplegia, myocardial infarction, cerebral infarction, and diabetic gangrene, causing lifelong regrets.

The causes of numbness in the hands and feet are related to the following situations:

1. Being oppressed

When the sleeping or sitting posture is incorrect and the limbs are in a state of oppression for a long time, it is easy to feel numbness or even no sensation. This situation is generally normal and there will be no big problem. It will be relieved quickly after some exercise, so there is no need to worry too much.

2. Cold and Frozen

The human body has a sensitivity to temperature. When the temperature is colder than the human body's sensitivity, the sensory nerves in the hands and feet fail, resulting in numbness and loss of sensation in the hands and feet. If the area is exposed to cold for too long, permanent tissue necrosis will occur.

3. Diabetes

If your hands and feet are often numb without being compressed, you should consider whether it is caused by diabetes. Diabetes can also cause body aches and swelling, so the elderly should pay special attention.

4. Medication

Some drugs or chemical substances can also cause numbness in the hands and feet under certain circumstances. For example, berberine and furazolidone can cause numbness in the hands and feet after taking them. If you stay in an environment containing hydrogen, arsenic, carbon disulfide, etc. for too long, it will also cause numbness in your hands and feet. Therefore, you must be careful when taking medicines and avoid going out for fun or walks near chemical plants.

5.Neuritis

Neuritis can damage the nerves in various parts of the body, causing them to not function normally and making the reactions of various parts of the body slow, thus leading to symptoms such as numbness in the hands and feet, muscle atrophy, and weakness in the limbs.

6. Nerve stimulation

When the nerves are stimulated, local numbness usually occurs, not numbness of the hands and feet at the same time. For example, cervical spondylosis causes arm numbness, lumbar shoulder nerve stimulation causes leg numbness, etc., all of which are caused by local stimulation leading to numbness in specific parts.

7. Drug reaction

Antihypertensive drugs, heart medicines, sedatives or paralytic drugs can cause local numbness of the limbs. Please take them according to your doctor's instructions.

8. Physical stimulation

Burns, heavy hammering, slapping, etc. can cause numbness in the hands and feet, which can be treated symptomatically.

Numbness in the hands and feet may not have any impact on your life or work at first, so it is easy to be ignored. If allowed to develop, it will lead to worsening of the disease, longer and longer numbness time, and may eventually lead to paralysis, so it must be taken seriously.
