Had Right Lobectomy. Diagnosed With Follicular Thyroid Cancer. Ultrasound Done. Showing Hypoechoic. Explanations Needed

I had right lobectomy last year and diagnosed with Stage 1 Follicular Thyroid Cancer. I was 43 yrs. old at that time. Since then I have visited the surgeon three times and 2 ultrasound done. The first ultrasound was free of nodule which was done last October of 2012. The latest was last week which really scared me since it mentioned a 3x2x2 mm nodule with hypoechoic and reduced ethnogenecity. All my blood work was normal . Last January of this year my endocrinologist started me with 75mcg. synthroid and I'm also taking some over the counter multivitamins, 1,000 mg. of Vit.C, Vit. D3 ( which my OBGyne had prescribed ). Having mentioned this is because I want to ask three questions.

A) Is the latest report be considered recurrent ? Or it's just nothing considering I have cancer history

B) What do you mean by 3x2x2 hypoechoic reduced ethnogenicity?

C) Do you think with all this meds, causes nodule appearance in my left Thyroid?

I really appreciate your answer and Thank you very much for all your time.
