Hi, I also had low Vitamin D, in the beginning, high blood calcium
, and a totally normal PTH
of 35, and I had surgery a few weeks ago, and they found 2 adenoma's, and I had 2 parathroid glands removed. My Endo ruled out all of the above cancer's, and I was really worried, especially when nothing was showing up on scans, but finally a MRI caught a nodule in the "Area", so they did surgery, and were very surprised. I had all of your symptoms. Don't panic!
