The fundamental problem is that to the doctor you're just one of 1000s of patients. Doctors are really happy if the get it 90-95% right. But what about those 5% they get wrong? To those individuals, it's their entire life and well being. Both my sisters are nurses and are all too aware of how careless and slipshod medical treatment often is. You need to be your own advocate and not placidly rely on the medical system. The internet makes it a lot easier to research issues and conditions. Sure there is plenty of misinformation out there, but there are also many legitimate sources of information...Mayo Clinic, WebMD, etc... Research these, and bring questions and information to your doctor. If they won't discuss it or take you seriously, get another doc.
