Hashimoto's thyroitis is a type of hypothyroidism
with episodes of hyperthyroidism
. This in simple terms just means that the patient either has a over functioning thyroid or an under functioning thryoid. Because of this, the patient has compression of the larynx
or the voice box. This can lead to hoarseess of voice and the symptoms that you have described.
What I recommend is for you to get treated for it properly by starting thyroid hormones for your condition. In this way, you will be able to get treated completely and not have symptoms. Before getting any treatment, please consult a endocrinologist
