We usually experience pain as a result of an injury or after we have
injured or hurt ourselves.
So while pain may vary from a mild discomfort
to excruciating, pain mostly serves to protect our bodies from further damage.
For example, if we did not feel pain, we would put our hand on a
hot stove and keep it there without knowing we were causing ourselves serious
Furthermore, when we have suffered an injury, pain serves
as a reminder to help us protect the injured part to allow for healing.
