I can relate. I was “an inch from dialysis” for over a year (GFR 8-10 for that long; BUN in the high 80s to low 90s). I had a kidney cyst rupture (I have PKD), and that did me in. I did dialysis for 9 months, and with the 7th call (almost 3 years on “the list), I got a 16 year old kidney.
Best of luck; I hope you keep off dialysis for as long as possible, but when you do need it, you will feel better (the fatigue, mental cloudiness, etc creeps up on you, and you don’t realize it’s extent until you start dialysis and even moreso, get a transplant).
That should be interesting. I've noticed those things, but I figured I was just getting old (pushing 50 now). If they went away...
