Why is there such an emphasis on “understanding” a child’s pain. Pain is pain, isn’t it?

Everyone feels pain differently. One person may be able to walk to the doctor on a broken ankle, while others will pass out or vomit because of the pain. Some people can have dental work without anesthetic, others need to be as frozen as is possible. Since everyone feels pain differently, it isn’t possible to say how a child feels pain. A child’s perception of pain may be totally different from that of an adult.
