I also just all my blood work back in today also. The ESR (SEDIMENTATION RATE) was 42, the T4 FREE is 1.19, T3 is 125, and the TSH is 1.63.
Would recommend seeing an endocrinologist for ultrasound guided FNA biopsy of this cystic mass. 95% of these are benign and most do not require surgery. Likely there was recent bleeding into a small pre-existing nodule or cyst. This usually improves in 3-4 weeks.
