I was told I have hyperparathyroidism, that's when your vitamin d level is low and your calcium levels can be low or elevated. My calcium level is normal. I read you can have a tumor. My Endrocrinologist without even testing for a tumor, just said take the vitamin d there is nothing wrong with you. Does anybody have this and have symptoms of anxiety. This has been going on for over a year now with dizziness when walking. Can anybody help PLEASE!
