Thanks for the response. The only other number I have is my TSH - it was 3.89
The heterogeneous gland is likely due to autoimmune thyroid disease (usually Hashimoto's). The nodules may need further evaluation including FNA biopsy but these may be inflammatory changes and nodularity due to the autoimmune thyroid disease. The lymph nodes are commonly seen in Hashimoto's.
Would test TSH, T4 and TPO antibodies to help clarify the thyroid status.
