Normal ft4, high calcium (10.9). everything else normal but very low d. thyroid ultrasound shows mild heterogeneous parenchymal echogenicity; no nodules. lots of symptoms and family history on moms side. should i see an endo?

I would talk with your primary care doctor about whether seeing an endocrinologist is worth your time. Your free T4 is normal which means your symptoms are not due to insufficient thyroid hormone. I would consider talking with your PCP to explore the reason for your symptoms. It is often helpful to explore the lifestyle closely (diet, sleep, stress, movement).
