4hw.com.cn: I believe that many people will find that their fingers are numb sometimes. In fact, the problem of numbness of fingers should not be underestimated. Numbness of fingers is the early signal of many diseases, if ignored, it will often cause disease deterioration, and early diagnosis can eliminate the disease in the bud. So what diseases does numbness of fingers indicate?
Cervical spondylopathy
The most common disease causing hand anesthesia is cervical spondylosis, which is one of the most common diseases in the elderly. When people enter middle age, with the increase of age, some organs will often have degenerative changes. When the cervical intervertebral disc has degenerative changes, it will often lead to the protrusion of the cervical intervertebral disc or the hyperplasia or hypertrophy of the articular process. Once these protrusions of the cervical intervertebral disc or the proliferative articular process compress the adjacent cervical nerve root, cervical spondylosis will occur. In addition to numbness and abnormal sensation of fingers, cervical spondylosis is accompanied by other symptoms, such as muscle soreness of neck and shoulder, radiation pain of upper limbs or dyskinesia, etc. It's not difficult to diagnose cervical spondylosis. Just take an X-ray. In addition, there is a simple way to check the cervical spondylosis. A person holds the head of the affected side, holds the upper limb of the affected side with one hand, extends it 90 deg., and pushes and pulls both hands to the opposite direction at the same time. The patient with radiation pain or numbness can be initially diagnosed as cervical spondylosis.
Entrapment of nerve
Numbness and pain of thumb, food and middle finger often have a history of waking up at night. After waking up, activities can be improved. Severe cases may be accompanied by muscle atrophy of the hand, which may affect the fine movement of the hand. This is because the median nerve is compressed at the wrist, that is, the so-called "carpal tunnel syndrome"; numbness and pain of the ring and little finger may also have a history of numbness at night. Severe cases may be accompanied by muscle atrophy, and the ring and little finger's bending force may drop, which may affect the fine movement. This is because the nerve is trapped in the elbow, known as "cubital tunnel syndrome.".
apoplexy
Another common cause of hand numbness is stroke. Although numbness of fingers does not necessarily lead to stroke, for the middle-aged people over 40 years old, if they often have headache, vertigo, lightheadedness, numbness of limbs, tongue swelling and other symptoms, and the patients usually have diseases such as hypertension, hyperlipidemia, diabetes, hardening of cerebral arteries, they should pay more attention to the occurrence of stroke.
Climacteric syndrome: women in menopause sometimes have hand numbness, but it is not obvious. The parts often change and are not fixed. With the end of menopause, hand numbness will disappear.
Transient ischemic attack (TIA)
Transient ischemic attack (TIA), also known as transient cerebral ischemia or 'small stroke', often suffers from hypertension, hyperlipidemia and other diseases. Hypertension will cause vasospasm, hyperlipidemia will cause the increase of blood viscosity, and the blood flow is relatively slow when sleeping at night. All these factors will lead to transient cerebral ischemia and cause unilateral finger numbness. Especially, the initial symptoms of multiple cerebral infarction are not obvious. The patients only feel numbness of hands and feet, which does not affect their life very much. If not found in the early stage, the best treatment opportunity will be delayed, leading to numbness Physical movement disorders, or even paralysis. Transient ischemic attack is a common and frequently occurring disease in neurology, accounting for 7% - 45% of ischemic cerebrovascular disease. In the first month after TIA, brain infarction occurred in 4% - 8% of the dead.
Diabetes
Diabetes can cause a variety of complications, if peripheral nerve lesions, there will be limb numbness and sensory abnormalities and other symptoms.
Rheumatoid arthritis
Numbness and distention of fingers is one of its early manifestations, and it is more likely to be accompanied by swelling and pain of joints. If accompanied by a hard skin on the face or fingers, it may be scleroderma.
Elbow of mobile phone
Cubital tunnel syndrome, commonly known as "mobile elbow" in recent years, is closely related to the frequent use of mobile phone products in people's daily work and life. Because when people use mobile phones to answer and make calls, the elbow often bends more than 90 degrees. Keeping the talking posture for a long time makes the ulnar nerve compressed or stretched in the elbow tube, which will lead to the numbness of the ring finger and the little finger into a 'claw shaped hand', or the thumb can't face to face, the thumb and the index finger can't face to face, the fingers can't be separated and closed, etc. In the same way, people who sleep with their arms on their backs also distort their elbows by more than 90 degrees. If they keep this sleeping position for several hours, it will also lead to the occurrence of 'mobile elbow'.
Peripheral neuritis
If the long-term digestion and absorption function is poor, malnutrition will cause the lack of vitamin B1 to cause peripheral neuritis, and also cause hand numbness. At this time, as long as we pay attention to increase some nutrition, we can supplement more vitamin B1.
Chronic alcoholism
For some people who often drink alcohol, if there is palmar numbness, it indicates chronic alcoholism. If chronic alcoholism is not intervened in time, it can lead to dysfunction of various systems of the body, even irreversible pathological damage, such as chronic gastrointestinal inflammation and ulcer, alcoholic myocarditis, fatty liver or cirrhosis, central nervous system degeneration or brain atrophy.
In a word, the diagnosis of hand numbness can only be made clearly by referring to cervical vertebra film, electromyography and other auxiliary examinations. Once the diagnosis is confirmed, if the symptoms are mild, the normal non-surgical treatment can improve in varying degrees. If the symptoms are obvious and the hand inner muscle atrophy is obvious, the surgical treatment should be taken in time to prevent the development of the disease, so as not to cause the irreversible serious atrophy of the hand inner muscle, leading to serious dysfunction of the hand.
