Finger numbness is a common clinical symptom. Patients often have numb fingers on the clinic and they are mistaken for cervical spondylosis. In fact, the common causes of finger numbness are more, but in many cases, the reason for finger numbness is not cervical spondylosis.
Here are some common reasons for finger numbness:
For middle-aged and elderly people, the most common cause of numbness is cervical spondylosis. When people enter middle age, some organs tend to undergo degenerative changes. When cervical intervertebral discs are degenerative, they often lead to cervical disc herniation or hyperplasia or hypertrophy of cervical intervertebral bodies or joints (commonly known as osteoarthritis). These prominent cervical intervertebral discs or bone hyperplasia, once the oppression of adjacent cervical nerve roots, sympathetic nerves, spinal cord, or blood vessels, cause cervical spondylosis, causing finger numbness, and even dizziness, limb weakness, walking claudication, defecation disorders, etc. . Cervical spondylosis with nerve root compression (called cervical spondylosis of the nerve root type), in addition to numbness of fingers and paresthesia, is accompanied by other symptoms, such as: bone and shoulder pain, radiating pain or movement disorders in the upper limbs. The diagnosis of cervical spondylosis is not difficult, as long as the majority of patients can be diagnosed by taking a single X-ray film, but magnetic resonance imaging is sometimes needed. There is also a simple method to check cervical spondylosis, one person cares for the affected side of the head, one hand holding the upper side of the affected side, the outreach of 90 °, both hands simultaneously push and pull in the opposite direction, there are radiation pain or numbness can be initially diagnosed as cervical spine disease.
For the numbness pain of the thumb, the food, and the middle finger, there is often a history of wakefulness during the night. After wakefulness (throwing the wrist), it can be improved or completely relieved; in severe cases, the hand muscles can be atrophied, affecting the delicate movement of the hand. This is because The median nerve is compressed at the wrist, the so-called "carpal tunnel syndrome"; if it is the numbness pain of the ring and the little finger, there may also be a history of wakefulness at night, severe muscle atrophy, and decreased flexion of the ring and the little finger. Impact of the fine use. This is because the nerves are pinched at the elbow, the so-called "Clinch syndrome" (ulnar nerve compression syndrome). Another common cause is the thoracic outlet syndrome, which is difficult to understand for non-professionals and involves anatomy. In general, due to the anatomical factors on both sides of the neck, such as ligaments, bones, and muscles, it is caused by compression of the subclavian vessels and brachial plexus on both sides or sides of the neck.
Clinical observations have found that people who often carry heavy objects can cause hypertrophy of the shoulder strap muscles and ligaments, which can lead to compression of neurovascular bundles, such as paresthesia of the inner arm, wood, hemp, and pain. Workers who regularly overextend their upper limbs or certain sports athletes are prone to symptoms of thoracic outlet syndrome in workers who have been in the position with their heads stretched forward for a long time, elderly people and middle-aged people with humpbacks. The normal upper arm movements such as arm abduction, sagging of the shoulders, stretching of the neck, turning of the face to the contralateral side, and intensification of the nerves and blood vessels caused by deep inhalation aggravate symptoms. The diagnosis of this disease is difficult. Although there are many inspection methods, it mainly depends on the degree of recognition of the disease by a specialist doctor. Detailed history of the disease is asked, and a comprehensive examination can lead to a comprehensive judgment.
Another common disease that causes numbness is cerebrovascular disease. Chinese medicine is called stroke. For middle-aged people over the age of 40, if headaches, dizziness, top-heeledness, numbness of limbs, swelling of the tongue, etc. are common, and the patient usually has high blood pressure, high cholesterol, diabetes, cerebral arteriosclerosis and other diseases. Should pay more attention to alert the occurrence of a stroke.
Women who enter menopause sometimes have numbness (usually bilaterally), but it is not obvious. With the end of menopause, the phenomenon of numbness will disappear; sometimes it is treated as menopausal syndrome or given anti-rheumatic Drugs and B vitamins may relieve symptoms.
Patients with clinically peripheral neuritis can also cause finger numbness. The disease is characterized by numbness of hands and symmetrical distribution of hands and socks.
In short, the definite diagnosis of numbness symptoms requires an orthopedic specialty. It is necessary to refer to the examination of cervical X-ray film, magnetic resonance, and electromyography in order to make a clear statement. Once diagnosed, if the symptoms are still mild, then the regular non-surgical treatment, can have different degrees of improvement, if the symptoms are obvious, and there was significant atrophy of the hand muscles, surgical treatment should be promptly taken to prevent the development of the disease, so as not to cause internal hand The irreversible severe atrophy of the muscles leads to serious hand-function disorders.
