Autoimmune problems can cause some mighty strange combinations of symptoms. A particular kind of kidney disease can cause skin problems, vision problems, hearing problems, as well as the kidney problems themselves. I have positive markers for ANA & RA, but do not have lupus or RA, as of yet. I do have kidney disease, and lots of other autoimmune crap, and some of your symptoms sound like my own. Good luck, I hope they figure out what’s going on, so you can get some relief!
