Fingertip numbness may be physiological reasons, or nerve root cervical spondylosis, diabetic peripheral neuropathy, cerebral infarction, carpal tunnel syndrome and other signs of disease. 1. Physiological causes: poor local blood circulation due to improper posture and prolonged compression, resulting in numbness of the fingertips. These are physiological factors that can be relieved with proper massage and rest. 2. Neurogenic cervical spondylosis: due to cervical disc herniation and other conditions, can lead to nerve root compression, affecting the hand nerve sensing and leading to numbness of the fingertips. 3. Diabetic peripheral neuropathy: diabetes may cause local nerve damage and easily complicate peripheral neuropathy, which may cause numbness of finger tips. 4. Cerebral infarction: this condition can be combined with high blood pressure, high blood cholesterol, etc., and early numbness in different parts of the body, accompanied by dizziness, fatigue and other discomforts. 5. Carpal tunnel syndrome: compression of the median nerve at the wrist may cause peripheral nerve entrapment, resulting in numbness of the fingertips. Long-term existence of numbness of the fingertips, need to pay attention to, timely consultation and examination, and then targeted treatment.
