Very high calcium levels and yet hypocalcemic post TT

[zingarella]

I was recently admitted to the hospital with a calcium level  of 16.5!  I had taken under 1000mg of calcium that day because I have parathyroid damage due to my Thyroidectomy.  I have been hypocalcemia for three years.  They still do not know why it happened.  I am taking 800-1000mg daily of Citracal, and Calcitriol .25 twice a day. They checked my PTH level and it was undetectable.  I also had low phosphorus levels.  I am worried about it happening again since I don't know why it happened. The only symptom I really had was menstrual-type cramping.

If parathyroids don't "work", typically, they are removed, in order to prevent problems.  Possibly, one or both of them "does" work, at least, intermittently in order to raise your levels that high? This does seem to be a parthyroid issue.

I supposedly have two parathyroids left but they haven't worked since my thyroid operation.  I am typically hypocalcemic (meaning low calcium levels).

You're worried about what, happening again?

High blood calcium often indicates that too much calcium is being pulled from your bones.  This is usually caused by a parathyroid malfunction or tumor. If it's known that you have parathyroid issues, why haven't the offending parathyroids been removed?
