Re: ?? could I be hyperthyroid
I'm over 90% sure the urine is for metanephrines. I was tested for it during the workup. It is an important test when dealing with labs and symptoms like yours and addison's should be ruled out too. The thyroid isn't the only thing that can cause the symptoms you're having and your endo is following a proper protocol on that. If those do come back negative, then it would be worth getting the ft3 and ft4 by any means you can get it. Either your gp if he's a sweety or order your own set online.
I hope you don't have to wait months either. I had to wait a long time for a diagnosis but now I'm doing a lot better.
