A while ago I complained to my GP about difficulties with my voice (very poor quality, scratchy, so low that my husband constantly complains that he can't hear me) and speech (slurred when tired, mixing words up, etc, cf. yesterday's post) (NB I have not been diagnosed with hypothyroid as all TFTs come back within range). She sent me to an ENT consultant who carried out investigations which involved a camera being inserted through the nose to the voice box.
Apparently, the camera also investigated the thyroid gland. The results came back wth the conclusion that there was nothing wrong with the thyroid.
Would this be a definitive or reliable test? On Thyroid UK all mention of testing the gland itself refers to an ultrasound (unless I've missed postings).
