Answer:A doctor is someone holding a Doctorate, which is a kind of degree. There are doctorates in virtually all areas of science, ranging from Medicine to Philosophy.
Within the Health/Medical fields, two types of doctorates exist. Some people hold both, either obtained independently, or through a special program / course of study, as may be elected for at Harvard Medical School for instance.
The first is the Medical Doctorate (M.D.), which is the kind of person I believe you refer to.
This is the kind of people that practice medicine and are in direct contact with people. They are the practical kind of medical doctors, but also the kind that is less in touch with the Science, Theory, and Truth of Medicine.
The second type is the Ph.D. in Medicine. This kind is mainly concerned with research and theory. They usually end up either doing research for a University or for private firms (mostly within the Pharma Industry).
Occasionally an M.D. may invent a medicine, but that is not their main occupation. Rather, it is usually Pharma companies that hire Ph.D.s to do research on various stuff and come up with medicines
