This is helpful to me, as I believe that many patients are left in a lurch by their doctors. I see it every day in my professional life.

I even bring stuff to my own doctor. Who was unaware that certain ACE inhibitors have shown promise in preventing Alzheimer's. (the lipofilic ones that is). Why use Vasotec (which is one that does not) when Lisinopril does? Both work fine for blood pressure.
If a drug salesman does not bring information to a doctor (who has a long busy hectic day), then that information not brought is not given to the patient.
Not everyone can have a research physician, in a teaching hospital.

I attended a long chronic pain conference in the spring, with all the speakers representing a teaching university. The sad truth is that their tertiary clinic does not take all insurances. So many people cannot avail themselves of that help.
If I can post it, here, perhaps people will find those answers, ultimately.
