I have early RA, just got the latest blood work back. My liver and blood count look great but my doc said my kidney function is slightly off. The creatinine is high at 1.09 and the GFR is low at 54. I was occasionally taking ibuprofen but have stopped completely now. I'm also on mtx, folic acid, norco for pain and also xanax. The doc said she wasn't too worried but she wants to watch it. I'm wondering if anyone else has had the same sort of thing.
