Abstract
Important medical advances over the last several decades have vastly improved the technical capacity to control human pain. Millions of patients suffering from cancer, HIV/AIDS, and other conditions have been able to find relief from incapacitating chronic and acute pain. However, despite these developments, pain remains severely under treated worldwide, particularly in developing countries. The tragic consequence is that for millions of people around the globe, excruciating pain is an inescapable reality of life.
