You'll want a doctor knowledgeable about AIDS and, preferably, one with plenty of experience working with HIV-positive people. Ask your doctor how many AIDS patients he or she has treated. Whether you choose a doctor who works exclusively with AIDS is a personal decision. A doctor knowledgeable about medical treatment for HIV illness will be able to provide you with more information and options. Like everyone else, doctors perform their jobs in many different ways.
Some doctors are more optimistic than others in their outlook for PWAs.
These are all questions you'll want to ask your current or prospective doctor. Follow your intuition. If you and the doctor are in conflict on many of these issues, chances are you will want to continue your search rather than find yourself shopping for a new physician later, when changing affiliations may be more complicated. Your doctor is someone you need to be able to talk with easily. For those taking an active role in their treatment, a certain amount of research and 'self-teaching' is involved.
