58, Caucasian, female never identified as having thyroid issues although now have 2.2cm nodule

Hi, I’m a 58 Caucasian woman. For about 6 months now I sweet profusely. I had a uterine ablation in 2015 which ended my menstrual cycle. I’ve had really bad migraines for over a year which cause nausea. On MRI have seen T2 Flair high intensities-white matter. Having memory issues. I have spinal stenosis in neck, back and SI joints. I have the HLN-B27 something like that. I went to the hospital and had a CT scan which showed thyroid right lobe calcifications. I was able to get into an endocrinologist. Via ultrasound nodule, more in the center, 2.2cm. Biopsy scheduled for 10/17. I have never had any blood tests to show my thyroid was not functioning correctly. Thoughts.
