Back pains started when i was 11, it developed to arthritis. At the age of 15 I had my first spontaneous fracture. I have normal calcium levels, very low phosphate levels ( Hypophosphatemia ) and high alkaline phosphate. The only medicine I take is Phosphate Sandoz but no matter how much i eat phosphate high food or take the medicine, my body doesn't recognize it, and no doctor understands where does the phosphate go. Now I am 19 and have both hip fixators , and have had around 10 spontaneous fractures. They have done so much research about my symptoms but nothing fits with some particular disease ( they have considered Oncogenic hypophosphatemic osteomalacia, but the tumor is nowhere to be found ). We have consulted around the world, but noone knows whats the reason behind this. I am desperate for help , I want to be healthy again!
