Honesty. Is the best policy! i/ we tell patients the truth. Risks, benefits, alternatives is our duty in my opinion!
No . There isn't a conspiracy. If we know what is causing your problem, we will tell you, even if we can't fix it. More importnantly, if we don't know what's wrong, it is usually something that will get better on its own. We are good at finding things that can hurt or kill you. Be patient.
