I constantly learn new things about Hashi's. I have had problems with hoarseness for many years without any illness present; doctors could find nothing wrong - how wrong they were! I recently discovered that the hoarseness can be one of the symptoms of a Hashi's attack! It explained so much for me. When will doctors stop masking symptoms with drugs and start doing tests, such as FreeT3 and FreeT4, plus both antibody tests? Hashi's should be tested for using both tests so that it can be at least ruled out! FreeT3 & 4 are much better indicators of thyroid function than the TSH, also.
