My 3 year old DS is due for renal ultrasound after me mentioning to his pediatrician about seeing a milky colour in his urine then it turns normal. He has chalky residue in his bed pants and underwear. Reading up on it, his symptoms fit with nephrocalcinosis. Anyone have experience with this? What happens?? What's the treatment? His doctors are vague, they are covering up what they picked up when he was a baby and failed to address it again until I mentioned it.
