I am having hyperparathyroidism - high blood calcium, lots of aches, high parathyroid hormone etc. The increased general aches are the most troublesome side effect so far, but doing nothing risks kidney, bone and heart health so I have to act. My doctor tells me that she sees this often in people who have had upper body, neck and head radiation in their pasts. I had this as a child, radiation to shrink my adenoids. I am wondering whether any other MM patients here who have had radiation in their upper bodies or necks to deal with spine pain or for some other reason have developed hyperparathyroid issues. I am scheduled for surgery in early November - they have visualized one of the four parathyroid glands that is enlarged so will take that out, then while I am on the table they will test my parathyroid hormone level - if it has come down they will close me up - if not, they will take the rest of the glands, leaving only one half of one of them which I am told is sufficient to produce enough hormone. So - has anyone else faced this?
