I just had my annual blood tests done and my GFR came back as a 56 which says it's stage III CKD. My Dr. said not to worry as I may just be dehydrated as my Creatinine was within the right levels (barely). I told her that I drank three 8 ounce glasses of water before the blood draw. I have also been diagnosed with high calcium levels via the 24 hour urine. I've had 2 now with no change. I'm also getting more and more calcium bumps under my skin on my forearms. I have Sarc in the elbows as well. I know I can get an honest response from this group! thanks much!
