My bones hurt and I bruise easily...?

Have they checked you for Hyperparathyroid? I was diagnosed with this several months ago. It does cause your bones to hurt, fatique, trouble focusing mentally and there are other symptoms. The condition is connected to Vitamin D deficiency. I was diagnosed with that before they diagnosed the Hyperparathyroid. If your blood calcium level is elevated and your parathyroid hormone is elevated then it means you have Hyperparathyroid. See an Endocrinologist if you think you have this. I hope this was helpful.
