I know this is an old thread, but I figured I would add in my recent experience and blood work. I went to my family physician with high BP (160-190/90-110 mmHg). I became hypertensive in the past few months. I noticed foamy urine while preparing for a show a few years back and didn't do anything about it. My physician took bloods and urine and called me within 2 days to let me know I was in kidney failure (GFR <15 and Creatinine was 550). I saw a nephrologist within a day and have been put on beta blockers and a low protein diet (0.8g/kg body weight). Blood pressure is now normal and I am scheduled for renal biopsies on Nov. 5th.

Scared shitless!
