Do night sweats and hot and cold flashes indicate thyroiditis?

Hi doctor,

I had an ultrasound done to check my thyroid. These results are copied directly from the report. It was mentioned that the thyroid gland is larger than normal. The right lobe size is 17x18.8x52.1 mm, and the left lobe size is 13.1x19.2x52.3 mm. Isthmus thickness is normal and is 3 mm. Gland parenchymal echo structure is significantly heterogeneous and rough. A diffuse micronodular appearance can be seen, and the vascularity is normal. No lymph node in pathologic size or nature is seen in the bilateral cervical lymphatic chain. And in the impression, it was stated as an increase in gland size, prominent heterogeneity in parenchymal echo structure, and coarsening, primarily indicating chronic lymphocytic thyroiditis.

I did a blood test, and everything was normal. My only complaints are night sweats and hot and cold flashes. My doctor has now stated that no further action is required because the blood test results show nothing is wrong. Is this the best course of action, or should something else be considered? Is there anything I should keep an eye out for? I want to know why my thyroid is the way it is, but I do not have any symptoms.
