First time posting!
I was diagnosed with proteinuria 20 years ago. I have taken meds ever since. In the last 2 years my kidneys have declined and I now have a GFR of 21. Dr. says next time I will register with transplant unit. I have changed my diet to be low potassium, but my dr hasn't said anything else would help. Looking at Dialysis by year's end.
I am sorry you are having these problems.
Have you been on any meds to control the Proteinuria in your urine?
I am currently taking 4-5 different meds for my condition.
