Question: My parathyroid hormone levels have been up and down for the last several months. I have had a general feeling of malaise for at least a year, with a severe bout of preeclampsia last May that led to a premature delivery. The doctors believed the preeclampsia was precipitated by some other existing medical condition but they have not been able to confirm that or diagnose it although they have diagnosed me with vitamin D deficiency. My calcium levels have been normal and my vitamin D was normalized after a 10-day run of 50,000 unit doses of vitamin D although it has slipped a bit again so I am continuing to take supplements. I continue to have bone pain, a "foggy" or confused feeling, migraines, chest tightness, and a pretty constant feeling that I am on the verge of getting sick (sore throat, ear pain, slightly swollen glands), etc. I have also had a recent problem with ringing in my ears and what feels like muscle spasms in my rib area. In the early part of December my PTH level was 89. I was told to take a "superdose" of Vit D for 10 days and be retested as my vitamin D was down to 13. After that I was retested and vitamin D was well within normal range, calcium was in the mid 9-s and my PTH was up to 130. I was sent to an endocrinologist who said my calcium levels were normal but the high PTH may be an indication of a tumor. He retested, told me my PTH was down to 23, and my vitamin D was low so I should start taking supplements again (4,000-5,000 units per day). I was concerned so my family doctor just retested me about a month later and my PTH is up to 79. I know that is still within the normal range but should I be concerned about these large swings? Is that ever normal? Except for right before I delivered, my calcium has been consistently within normal ranges. Any advice would be greatly appreciated. Thank you.

My calcium was never low. Once my vitamin D normalized my PTH XXXXXXX to its highest level, 129. Is that still attributable to the vitamin D issue? Thank you.
