Thyroid problems very often evidence themselves in the patient's body temperature.
For way, way less than the cost of an office visit, you can purchase a highly
accurate liquid metal basal thermometer. I own a Geratherm, which I recommed highly.
An occasional one time spin with an inaccurate digital thermometer at the Doc's office sure won't tell you very much.
So, once you have an accurate liquid metal thermometer take your temperature three times a day and keep a log. There is plenty of information on this procedure on the web. Answering this fundamental question is well within your ability, your budget, and your control. Good luck.
