My experience is as a patient but I can say that many times, I have preferred a PA over an MD because PA's seem to be more relaxed and spend more time with the patient. I believe it is a very worthwhile career and would like to encourage you to pursue it. I believe that PA's and Nurse Practitioners both have medical school but not the internship. Find out all you can and make a decision based on as much information as possible. Best wishes to you in your future !
