In clinical work, numbness in the fingers is one of the more common symptoms. There are many causes of numbness in the fingers, but the most likely diagnosis is cervical spondylosis, transient cerebral ischemia, diabetes, peripheral neuritis, etc. I. Cervical spondylosis The most common disease that causes numbness in the fingers is cervical spondylosis, which is one of the diseases that occur in middle-aged and elderly people, and there is a trend of rejuvenation of this disease. Due to long-term sedentary reluctance to move, abnormal neck posture, especially the computer phone application time is too long, so that the cervical intervertebral disc degeneration, resulting in cervical intervertebral disc protrusion or joint protrusion hyperplasia or hypertrophy, these protruding cervical intervertebral disc or hyperplasia of the joint protrusion once the compression of the adjacent cervical nerve root, there will be numbness in the fingers. Of course, in addition to numbness and abnormal sensation in the fingers, cervical spondylosis is also accompanied by other symptoms, such as muscle pain in the neck and shoulders, radiating pain in the upper limbs or movement disorders.

Transient cerebral ischemia Numbness in the fingers is one of the common symptoms of transient cerebral ischemia, especially when it is on one side, and it occurs in the elderly. It usually starts suddenly, lasts for a short time, and is often accompanied by other symptoms such as limb weakness, dizziness and headache. The causes and pathogenesis of transient cerebral ischemia are mostly the dislodgement of microemboli in the cerebral artery wall, the fall of blood pressure on the basis of cerebral artery stenosis, and cerebral vasospasm. If the above-mentioned symptoms appear, you should go to the hospital in time to have a comprehensive screening for the risk factors of cerebrovascular disease, such as hypertension, hyperlipidemia, hyperglycemia, atrial fibrillation, etc., and give active prevention and treatment. Diabetes mellitus Bilateral symmetrical numbness of the fingers is a common symptom of diabetic peripheral neuropathy. Epidemiology shows that the prevalence of diabetes among Chinese residents has reached 2.4%, and the total number of people with diabetes has reached 31 million.

Therefore, after suffering from diabetes, it is necessary to carry out regular and reasonable treatment, to control blood sugar to the normal range, and pay attention to the supplementation of multivitamins, and also with the application of drugs to improve blood circulation, the numbness of the fingers will be eliminated. Peripheral neuritis numbness of the fingers with pain and weakness, bilateral symmetry, suggests the possibility of peripheral neuritis, which can be caused by a variety of reasons. The clinical manifestations vary slightly depending on the cause of the disease. The pain is more intense if it is due to poisoning, and the weakness and numbness are more pronounced if it is due to a nutritional metabolic disorder. In general, the disease progresses slowly and recovery is more difficult. In summary, if the problem of numbness in the fingers, it is best to find a doctor to diagnose the specific cause of the disease, the right treatment, do not buy their own drugs to take, so as not to delay the time of treatment.
