I’m in 3rd stage kidney failure and I’ve had that crazy itchiness a couple times and it’s horrible to go through. I’m not on dialysis. Mine was really bad a year or so ago and I itched so bad that I bled. It comes and goes in spurts and I haven’t told my doctor about it but I itch on my back a lot and I see blood on my clothes. I didn’t know it’s a diabetic thing. I can empathize with the patients that have it.
