Thank you for sharing this side of the story so well. The truth is that the AMA keeps the quacks out and standards high.
My wife spent years going to different doctors trying to figure out what was going on with her back. For years, different doctors would just tell her, "you must just be starting your period or something." 5 years of that, she finally found a doctor who actually looked at her and listened to her, did some testing and came back with an answer that she has some arthritis.
