Should i push for the thyroidectomy?

I have a 2cm nodule in my right thyroid. My bloodwork always comes back normal but i go thru periods where im freezing and then for a while i have periods where all i do is sweat. Spent 2 days in hosp for tests and they told me that thr left side has no nodule but is enlarged. the right side has the 2cm nodule and is also enlarged. what do i do? i go see an endocrinologist this thursday and i just want to stop feeling like crap...what do i ask?
