I had a totally NORMAL PTH level, high blood
calcium, 10.5 up to 10.9, high ionizied
calcium,
and low vit. D also,
and I had 2 parathyroid adenomas. I had lots of the same symptoms as you. I had this for several years, then changed Dr's, who saw the high blood calcium, and sent me to a Endocrinololgist, who ran lots of tests, did all the scans, and finally a MRI picked up the tumors.
