Cheapest way to see a dcotor?

what is the best way to minimize the cost of a doctors visit. For example I already know the symptoms of my problem so I dont need to pay a doctor to tell me what I already know and can observer, but I need testing done so how can I go about getting the testing done without paying the doctor charge. Its like taking a car to the shop knowing you need your breaks changed, so you would not go to the mechanic and pay him to tell you that you need your breaks done then pay him to change your breaks, you would just pay him to change your breaks.Cheapest way to see a dcotor?
Try a medical clinic at any teaching hospital. There, the student doctors will see you, at reasonable rates.Cheapest way to see a dcotor?
Everyone know the symptoms they have. They would probably have to check before they prescribe anything. Or, move over here to England, and get it through the NHS.
