What is the reason for finger numbness? What should I pay attention to when my fingers are numb?

Numbness of fingers is seen in many diseases,

First, my fingers have been hurt, and when I meet cold water, I will feel numb in cold weather. Second, finger numbness may be caused by cerebrovascular disease. Third, like cervical spondylosis, it may squeeze blood vessels and nerves and affect microcirculation, resulting in numbness of fingers. I suggest you do relevant tests to rule out the disease. If you can't find the cause, you can treat it with Chinese medicine.
