Hello all. I have had CFIDS for over a decade and have been mostly homebound for the last 6 years (with no other diagnosis to explain my condition). I the past 4-5 months, I have experienced intense itching all over and foam in my urine. I went to a nephrologist (kidney doc.) a few weeks ago and he did a 24 hour urine test. The results are that I have high protein in my urine as well as a low GFR. My Vitamin D and magnesium levels are low as well. He said that I am likely in the early stages of kidney disease and possibly diabetes. My test results indicate stage 2. I know that Dr. Paul St. Amand believes that CFIDS/Fibro are caused by the inability of the kidneys to remove phosphates. So, has anyone else gone from CFIDS/Fibro to kidney disease?
