Sounds kind of like me. I don't know how long I've had CKD. I go to the VA. I had Salmonella back in Oct 2018. I finally ended up in the hospital on Nov. 28 2018 with an UTI. My primary doctor had no idea what was wrong with me.
She noticed my Iron and Vitamin D going down a couple of years ago. I am 72 years old. She seen protein in my Urine in Nov. 2018 and didn't know what to do. WBC said clumps in Urine. Which means there's an infection. In May another Doctor said I had 37% Kidney function. Again Urine was filed with WBC and again no mention of UTI. VA don't know what they are doing.
