I have an over active thyroid and have been told that I need it removed, they said I will be on thyroxcin for the rest of my life, but that it is easyier to treat once removed. Is this true? and if it is why do people with under active not have this treatment, or is there another reason why they don't. Sorry I just don't know enough, but most people on this sight have an underactive thyroid mine is the other way. Will I feel like you after or is it as controlable as the doc says. ?
