I have never heard of thyroid nodules going away on their own.
Options are: ignore them; have them biopsied and scanned; treat them with radiation if needed; or have the thyroid (half or whole) removed. All of this depends on what the nodules consist of, whether there is problem with overproduction of hormones, whether there is a chance of malignancy, and if they are large enough to compress any other structures in your neck.
You need a good endocrinologist who specializes in thyroids to go over the options with you and to run some more tests so you both have a good idea what you are dealing with.
