What is the essence of local anesthesia?

In the case of local anesthesia, the doctor will numb the skin and internal tissue at the site of immediate surgery. At the same time, a person is conscious, feels a touch, but does not feel pain, therefore, certain chemicals have blocked pain receptors in the skin and muscles. For small operations, it is better to use local anesthesia, since general anesthesia is a difficult test for the body.
