This is going to be long, and a apologize for that. I do appreciate that you are willing to read and answer these questions.
I am a 52 year old active woman. I suffered a very painful insufficiency fracture of my sacrum this winter. I have since learned that I have osteoporosis of my pelvic region and osteopenia of my lumbar spine. My calcium ranges around 10.9, HPT around 30, Vitamin D around 39. I have seen several doctors who have ranged in opinion from I am fine, do not worry about the calcium to doctors who tell me I have bone cancer, but cannot locate the cancer. None of the blood work supports cancer, multiple myeloma and kidney and liver are all completely normal.
On April 17th, I was given an infusion of pamidronate to control bone pain and hypercalcemia. Two weeks after the infusion my calcium was 9.7 and 6 weeks after the infusion my calcium was 10.3. I am being treated by a endocrinologist at a prestigious Chicago University and she tells me that I cannot have hyperparathyroidism because my HPT is too low and my vitamin D is too high. According to parathyroid.com, I could have hyperparathyroidism, but my vitamin D is too high. (It should be noted that I take 500 mg of calcium and 200IU of vitamin D 3x per day.)
I started taking the calcium and vitamin D supplements in April of 08, but my calcium has been in the 10.3-10.9 range since January of 2005. The first vitamin D blood was not taken until after I had been on the supplements. I also take a thiazide diuretic, but didn’t start that until April of 2008 so docs do not think that is causing the elevated calcium.
I am ever so curious as to what your opinion is as to my current situation.
