Numbness in the hand

Introduction Hand numbness is a common symptom in hand disease. It is pulled by tendons from different directions. The displaced tendon is pulled in different directions, causing tearing of the collateral ligament to the dorsal side. The nerve is jammed.

Cause

The reasons for numbness in hands and feet are:

1, people with diabetes will have numbness in the hands and feet, mainly caused by vascular disease.

2. It is numbness caused by drugs or chemicals.

3, is the numbness caused by neuritis.

4, the limbs scattered numbness. Local nerves are stimulated, such as stroke after drunkenness, coma caused by head nerve stimulation, cervical spondylosis caused by upper limb numbness, lumbar shoulder nerve stimulation caused by leg numbness.

5, is the numbness caused by compression nerves such as tumors.

6, is the ion disorder, acid-base imbalance, endocrine disorders, psychological factors.

1, upper limb nerve compression: First, the numbness of the thumb, food, middle finger, often have a history of nighttime awakening, wake up activities can be improved. Severe cases may be accompanied by hand muscle atrophy, affecting the fine movements of the hand, because the median nerve is compressed on the wrist, the so-called "carpal tube syndrome"; the second is the numbness of the ring, the little finger, but also the night A history of waking up, severe cases accompanied by muscle atrophy, the flexion of the ring and little finger decreased, affecting the fine use. This is because the nerve is jammed at the elbow, the so-called "elbow syndrome."

2, cervical spondylosis: the most common disease causing hand numbness is cervical spondylosis, which is one of the most common diseases in the elderly. When a person enters middle age, some organs tend to undergo degenerative changes. When the cervical disc is degenerated, it often leads to cervical disc herniation or hyperplasia or hypertrophy of the joints. These prominent cervical discs or hyperplastic joints Cervical spondylosis occurs when the adjacent cervical nerve root is compressed. In addition to finger numbness and abnormal sensation, cervical spondylosis is accompanied by other symptoms such as neck and shoulder soreness, radiation pain or movement disorder in the upper limbs. It is not difficult to diagnose cervical spondylosis, just take an X-ray film. There is also a simple method for examining cervical spondylosis. One person holds the lateral head and holds the upper limb of the affected side in one hand and abducts it 90°. Both hands push and pull in the opposite direction at the same time. Those with radiation pain or numbness can be initially diagnosed as cervical vertebrae. disease.

3, stroke: Another common cause of hand numbness is stroke. "Health Baojian? Zhongfengmen" once said: "Where mortal people feel that the big finger, the second finger is numb or not used, there is a stroke in three years." Prevention: should be careful, daily diet, far away, wide Emotional. Although the numbness of the fingers does not necessarily cause a stroke, but for middle-aged people over the age of 40, if there are frequent headaches, dizziness, top-heavy, numbness of the limbs, swelling of the tongue and other symptoms, and the patient usually has high blood pressure and high When blood lipids, diabetes, cerebral arteriosclerosis and other diseases, should pay more attention to alert to the occurrence of stroke.

4. Menopausal Syndrome: Women who enter menopause sometimes have hand numbness, but it is not obvious. With the end of menopause, the hand numbness will disappear.

In short, the diagnosis of hand numbness symptoms, but also need to refer to cervical vertebrae, EMG and other auxiliary examinations to make a clear statement. Once diagnosed, if the symptoms are still mild, regular non-surgical treatment can be improved to varying degrees. If the symptoms are obvious and there is obvious atrophy of the intramuscular muscles, surgical treatment should be taken in time to prevent the disease from developing. The muscles are irreversibly severely atrophied, causing severe functional impairment of the hand.
