People don\'t walk around really not knowing what\'s wrong with them, unless it\'s some frightening symptom like rectal bleeding. Of course, the majority of folks are not going to get a book and read up on it and try to treat it. But those ailments that have become common, the info is out there. The NDs in my area charge $150 to $350 for an office visit. With easy access to the internet, health magazines & books all over the place, people are trying things themselves and getting results without the expensive office visit.
