I have secondary hyperparathyroidism with no kisdney problems. Calcium and vitamins levels are normal. My symptoms are extreme tiredness, low energy, depression and anxiety. This has been going on for two years. also have osteoporosis. My endocrinologist has referred me to Mayo . I’ve had every test there is and he is very perplexed. I just turned 78. I feel 87. Up until 2 years ago I had a vital life - exercising , being withbfriends etc. now I stay at home with very little energy or hopefulness-
