hi there, i have been having tests for random symptoms for the last 3 years, and i kept getting told different things, in the end they discovered i have a hyperactive thyroid but yet one doctor says my symptoms are because of that and one says they are not. Thyroid does funny things to a person, i would recommend that you get a second opinion and probably by someone who knows more about it than your general doctor. Hope thats some help.
Do you have the results of your latest FT3, FT4 and TSH tests and their reference ranges?
