Medicine
Medicine is the science and practice of the diagnosis, treatment, and prevention of disease. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.
Pain
Pain is a distressing feeling often caused by intense or damaging stimuli. The International Association for the Study of Pain's widely used definition defines pain as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage"; however, due to it being a complex, subjective phenomenon, defining pain has been a challenge. In medical diagnosis, pain is regarded as a symptom of an underlying condition.

Of all the forms of inequality, injustice in healthcare is the most shocking and inhumane.
