I read up on Prolia too and refused the treatment. I was really annoyed with the endocrinologist for not explaining the full potential side effects to me, except that I might feel sick for a few days after. I later found out that my calcium levels are fine and should not be taking any calcium supplements as doing so could cause other problems. It’s so hard to know what to do. Since I exercise and have a good diet and take a multivitamin, I’m just going to keep doing what I’ve been doing.
