It's not only the doctor, but the entire health care system including insurance.
My wife has similiar symptoms, of which they call endomitriosis (sp). She has gone through several tests over the last 3 years, even surgery through her belly button which did nothing for her. Even though we have insurance, we have spent well over $7k of our own money, and for nothing.
I had a problem last year with a urinary infection, don't know how I got it but it bothered me after several weeks of trying to rid it. So I went to the urgent care to see about getting antibiotics. Upon arriving and describing my symptoms, I was treated extremely rude by several people including the doctor (after leaving I arrived at the conclusion that they thought I had been sleeping around on my wife and cought some STD) Several tests proved otherwise, and their antibiotics didn't work. I then went to my primary phys who ran the same tests again proving otherwise, and was sent to a urologist, who ran tests, and found no problem. So he decides that my insurance will pay to run a scope (ouch) just to check everything out. Well, no problems there either, except for me pissing blood for a week, and a $1600 deductible on my insurance.
The entire medical system is based on making money, insurance is based on making money, hospitals want to bleed the money, and they all play the game. They make us feel like we are getting the best treatment, when in reality they diagnose problems starting with the least succeptable, and working from there.
They say National Healthcare will lower the standards of our medical treatments, and put several doctors, ins companies out of work. I say screw them, let em fall.
