My high level of calcium in the blood was discovered when I was going through some tests before a bone marrow donation in 2009, in my early 40s. I followed up at Mayo in Rochester and had 2 noncancerous parathyroid tumors removed there, although I had no symptoms I didn't want it to progress to a bigger problem. A bone density scan showed I was in osteopenia. I followed up with diet and exercise recommendations fairly well over the following decade. Just had another bone density scan in 2021 and I had progressed to osteoporosis in my lower spine. My doctor started me on Fosamax (oral tablet, once a week). I do worry a bit about the side effects, but as an active person who loves to ride horses, I was more concerned with the prospect of weak bones. So far so good, and I am happy with the choices I've made.
