Numbness in the fingers is a frequently encountered symptom or sign who is self-perceived numbness in the fingers, with or without a decrease in hand strength. Most people consider numbness in the hands to be generally cervical spondylosis, and mostly use treatment for cervical spondylosis to treat numbness in the hands. However, numbness in the fingers is not always cervical spondylosis. After finding numbness in the fingers, first clarify the several diseases that cause numbness in the hands, the incidence of middle-aged and elderly from high to low: 1, neurogenic cervical spondylosis: this condition causes the most common numbness in the hands, which is often accompanied by pain and discomfort in the neck, numbness, and the course of the disease v. more than 2 weeks, sometimes able to relieve, but aggravated after exertion or cold. MRI and CT of cervical spine can be done to confirm the diagnosis. 2, transient cerebral ischemia or cerebrovascular lesions: in this case, the hand numbness is transient, mostly accompanied by other unfavorable limb activities, distorted mouth and eyes, drooling, or walking Louis and falling, etc. Most of them are accompanied by other problems of the nervous system. It is recommended to perform cranial MRI and CT examination. 3, diabetes: diabetes caused by hand numbness is mostly seen in diabetic patients, poor blood sugar control, or has not been able to actively control blood sugar, resulting in peripheral nerve and vascular damage, more complaints hand like a glove. In this case, actively test blood sugar, apply hypoglycemic drugs or insulin to control blood sugar. Apply nerve-nourishing drugs. 4, peripheral nerve entrapment: seen in carpal tunnel syndrome, elbow tunnel syndrome, etc., whose numbness is sometimes accompanied by rest pain at night, the intense pain of the entrapment point or can trigger the aggravation of the numbness pain area is a characteristic of the disease, this situation requires finding the location of the entrapment, surgical release or acupuncture treatment. It should be noted that sometimes lung and thyroid tumors can also compress nerves and cause numbness in the fingers, so more attention should be paid to them. In conclusion, although numbness in the fingers is a small problem, it needs to be actively controlled and taken care of. Moreover, these diseases are preventable and controllable. Early treatment is effective, but with the prolongation of nerve compression or ischemia, it will be difficult to relieve the symptoms.
