Yes, I have dealt with elevated PTH. One of the parathyroid glands was enlarged and was causing the problem. I had surgery in September, 2018 to remove the gland which was 750mg as opposed to the normal 15-30mg. I developed osteopenia as a result of the parathyroid gland. I also had excruciating bone pain and fatigue which impacted my Fibromyalgia tremendously. When I awoke from the surgery the first thing I noticed was that the bone pain was gone. I recovered quickly overall but it did take me several weeks to regain my normal voice.
