HPT did affect my thyroid but no nodules to my knowledge...It also gave me hypercalcemia, kidney stones
, period weirdness, back and joint pain, gall stones
, headaches, heartburn, and having to urinate every 25 minutes...Oh, gut trouble too...(I'm sure there was more that I've blissfully forgotten!).
The Sestamibi scan is no big deal. You have a prescan, (I didn't even have to get undressed!), get an IV injection of isotopes, hang out for 20 mins, and then get scanned again.
