Love the statement about the doc treating the lab sheets, that is unfortunatly so true sometimes.
I am afraid they most likely tested only the TSH again, I know it makes you want to scream, feels like you are on a never ending merry go round.
Request the T4 free and T3 free and thyroid antibodies, fight for it, its not going to hurt the doc to order those tests, although it may hurt his ego. With your symptoms I can't believe they are not listening, typical doc, too busy to really listen and doesn't care because he isn't uncomfortable so you have to PUSH to get what you want.
Good luck to you, keep us updated.
