Therefore, I have the following suggestions:
1. There is something wrong with the cervical vertebra.
For people with cervical spine problems, there will always be such a situation, especially those elderly people. With the gradual decline of their physical function, when the cervical vertebra has degenerative changes, we will feel that our nerves are oppressed, which will lead to numbness. Because my mother-in-law was like this, she always said that her fingers were numb at that time, but because of too much farm work, she missed the best opportunity to go to the hospital for treatment and caused her fingers to be disabled.
2. lack of vitamin B.
As we all know, the normal function of the body is inseparable from nutrients. When a person is short of vitamin B, if the finger is infected locally and blood supply is not available, then our fingertips will be abnormal, the most obvious performance is the ring finger of the right hand, so everyone must pay attention to these small details.
The above points are all my personal opinions, and I hope they can help you. At the same time, I hope everyone can learn more about this common sense in peacetime, so that they can not only increase their knowledge, but also find their own problems in advance. I hope everyone can adopt this view.
