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 injury.

Furthermore, when we have suffered an injury, pain serves as a reminder to help us protect the injured part to allow for healing.
