I'm new here. I am 16 and have a function in my left kidney of 27% and my right 76%, I have had a low function since march 2013 and it had just gone down and down. I have been having back pain, feeling nauseous, feeling fatigue, have a shortness of breath, struggle to concentrate in school and at work and just at home cooking dinner, and am loosing my appetite. What does my function being this low mean? Do I need to go on dialysis with my kidney function this low in my left kidney, and what do these symptoms mean?
