I had my thyroid checked and was told it was normal. Still, I thought I would get a second opinion, so I made an appointment with an endocrinologist. Ninety days later, I got to see him. He said, "Well, we'll have to do these tests all over again." In other words, there is no such thing as a second opinion anymore. Everyone starts from Square One, everyone does their own tests, and everyone (except me, of course) makes money. I didn't see any reason to start again with the endo, tho I can always go back, if I change my mind.
