Hand numbness is relatively common to the phenomenon, generally arm nerves are compressed, such as a long time to lift heavy objects, long time to let the arm to maintain a posture, etc., will cause hand numbness, which is not too concerned, let the arm rest a little rub a good, but if the disease caused by hand numbness need to pay attention to, some people will be in the usual good time will be numbness, this is the body of some kind of disease in a person to give This is the body of a disease in a person’s a kind of hint, we must be correct and timely treatment. Generally older people should pay special attention to the occurrence of hand numbness, serious times due to hand numbness even take things the strength is not even eat can not pick up chopsticks, if such a phenomenon must be timely medical treatment to find the cause of the disease, in order to prevent the body from the occurrence of larger diseases, the following we would like to introduce the hand numbness of a variety of reasons, I hope that today’s introduction to be able to together with everyone’s enough attention. Causes of numbness of the hands and feet Vascular factors When we sit for a long time or sit in a bad posture, will cause numbness of the lower limbs, when the hands put in the wrong posture will also be numb, a slack, like millions of ants crawling. Because when the blood vessels are compressed, the blood vessels supply part of the limb ischemia, causing numbness, and so on a moment to lift the compression, blood flow over, it feels like a lot of ants in the crawl. When the ulnar artery of the upper limb, radial artery tube in a certain place of pressure, will cause hand numbness. Neurological factors Nerve axoplasmic flow, when the nerve is compressed, axoplasmic flow is impeded, will also cause hand numbness. To the palm of the main radial nerve, ulnar nerve, median nerve, these nerves from the cervical spinal canal, through the joints, ligaments, bone fiber tube to reach the end of the palm, in any part of the nerve is compressed, will cause hand numbness. Brain factors All nerves originate from the brain, when the brain problems. Such as stroke, the brain will be dominated by the area of numbness, weakness. Systemic factors Hyperlipidemia: long-term high blood fat, easy to cause hardening of blood vessel walls, coupled with high blood fat, blood viscosity, blood flow slows down, the cells get less oxygen nutrients, resulting in numbness. Diabetic: blood sugar to maintain a high level, for a long time, on the human blood vessels, nerves cause great harm, vascular sclerosis, nerve degeneration. Numbness caused by cervical vertebrae The cervical nerve comes out of the intervertebral foramen and is divided into two branches, the anterior and posterior. The anterior branch: toward the lower outer side, until the forearm, constituting the ulnar nerve, radial nerve, median nerve and so on. Posterior branch: around the back of the cervical joints to the rear, distributed in the muscles behind the cervical vertebrae, the skin, whether the anterior or posterior branch is compressed, will cause hand numbness.
