My recent US of thyroid said: Normal size thyroid gland at present. Normal size thyroid gland with heterogenous echotexture and nodules in both lobes. Do I need to follow up with a FNB? Im 62, female on synthroid over 6 years, hx of DCIS 1998. Very tired, hair loss, brittle nails. Working as a Nurse Practitioner. Hoarsness, can not sing like I used to. Some notes can not even do anymore. Thank you
