multiple nodules, now larger and hypoectoic?

Hello my name is (…), I’m 53 year old female and I have a history of high blood pressure, acid reflux and enlarge thyroid with multiple nodules. On my last ultrasound in 2014 it showed I had multiple nodules did a biopsy and they came back negative for cancer. 12/21/2016 I had another ultrasound done and it came back with multiple nodules, but this time their larger and hypoectoic, been having a lot of pain in my throat along with some choking when I eat, or drink something and my voice has change to were it’s deeper. Can you tell me just want is going on with me. I want to just have it removed and be done with the unlikely chances that it’s cancer.
Thanks,
