No sir I do not try to tell my dr's how to do there job. I do educate myself on various treatments / medications and Diagnosis the dr's suggest. If you go into the dr's with the attitude you suggest your less likely to get a proper diagnosis and treatment, (See Overreading into things).
That being said, My mom was a MA on her way to be a nurse before she joined FCSD, During that time I helped her study and read all of our textbooks. So I do understand a little better than most what the dr's are talking about, So when I speak to the dr's about my wife (When she has been in the hospital) The dr doesn't need to spend 10 minutes explaining simple shit.
