This app saved me from years of horrible pain and symptoms and future emergencies. Negative reviews are either from a period of time when they had a few bugs, or from people who have decided to believe what their doctors say over what this app says. That’s their prerogative, but it doesn’t mean this app is worthless or a marketing tool to get business. That’s just not true. The medical community is playing catch-up and do not have paralleled data or experience equal to the amount that this clinic has. That’s just the truth, so of course this clinic is going to want you to either come to them or educate your own doctors with the data that they have. Just ask your doctors like I did. They admit they don’t and can’t show me any data to support their approach to this disease. Some with egos larger than their ethics will go so far to scare you away from this clinic. I spent 9 months letting doctors hem and haw over what might have caused such severe osteoporosis at my age. I had T-scores that were common only to people 30+ years older than me. Young 50-year olds should not have such significant bone loss in the critical range. I was scared to bump into a wall and break my hip or spine! I broke my rib this year simply laying on my stomach. Because of inappropriate blood test reporting and reading, my doctors ruled out hyperparathyroidism in the blink of an eye that first month and almost started to dose me with osteoporosis drugs. They wouldn’t let me share symptoms that they didn’t think had anything to do with osteoporosis, but they did have a lot to do with my endocrine system! Nobody was taking my condition as serious as they should have been or seeing that someone with such low T-scores deserves every possible stone turned over to be absolutely sure of the cause. And I needed aggressive treatment to rebuild my bones, not the kind given to someone with osteopenia. I pushed the matter and new doctors did more testing. But again, there were mistakes reading the sestamibi scan and the doctors trusted what the radiology report said, that nothing was there. Again I was scheduled for drug treatment to rebuild bones, but with a more aggressive drug. But that scared me too. How could they be so sure it wasn’t my parathyroid? Why were they basing it off of a scan that is wrong 50% of the time and my lower end “high calcium” results not being high enough? My PTH was continuously high all year, between 75 and 115, and the highest a 50-yr old should have is 65. But improper lab reports only show normal ranges for a 20-yr old and that placed my result at the high end of the normal green zone or just to the right of it. It caused all doctors I had seen to not think it was my parathyroid and allowed my condition to degrade further. That made me start to search for more information about this disease and I found the NPC website and downloaded this app. I was lucky enough to have years of blood tests to enter into this app, and a full 8 months of multiple calcium and PTH testing results. The result slung the red needle way over into the extremely likely range for having hyperparathyroidism and a tumor. Just out of curiosity, we entered data for my husband, and his needle stayed firmly in the highly unlikely range as it should have. I also have had 16 of the listed symptoms continuously for the past 5-6 years - all having no conclusive diagnosis or any idea what was causing them, but also a tortuous calcium kidney stone that required surgery to remove, broken rib, severe osteoporosis, and losing 3/4 of the hair on my head (something the endocrinologist said had nothing to do with my osteoporosis even though it is common in hyperparathyroidism which causes osteo.) But I had most of the atypical symptoms too. So I pushed with my doctor again, and got an ultrasound of my thyroid, that saw a tumor. If they had not agreed to give me that scan, if I had not researched on my own, if I had just trusted my doctors, they never would have considered parathyroid again and would have given me a drug that would have done nothing except expose me to potential negative side effects. But the radiologist report said, “unlikely to be of parathyroid origin…”. How on earth does he know? He is not an endocrine surgeon and has no experience treating this condition. But finding anything was enough to refer me to an endocrine surgeon finally. Talking with a surgeon, I found the previous primary sestamibi scan of my parathyroid that came back negative was wrong! They could see the tumor plain as day and it was obvious it was my parathyroid. They simply said the radiologist made a mistake. Ya? It cost me months of my life while my bones continued to degrade. But they would only remove what the scan showed and would not test the other parathyroid glands, even though my osteo is so severe and there is a 20-30% chance that there is a second one that does not show on the scan, so of course I chose to go to NPC. This app was the only thing keeping me grounded and not feeling like a difficult to treat hypochondriac, which I often felt like over the past 9 months. It didn’t assume I couldn’t understand medical jargon or testing results. It educated me better than ANY of my doctors, one of which reminded me that I wasn’t a trained surgeon so couldn’t possibly understand their opinions. Seriously? I have a computer science degree, shall I say they couldn’t possibly understand any explanation I give to them about how computers work? That’s insulting their obvious intelligence! Bottom line, I have lower high calcium with high PTH and severe osteoporosis, and it’s because I have a parathyroid tumor that has been growing for several years. It is coming out this week and only because of the education and drive that this app gave to me. I can’t guarantee ALL my horrible symptoms will disappear, but those caused by my tumor will, and that treats my quality of life. Something my doctors forgot was supposed to be their mission.
