Drink water - this is critical to keep the toxins in your system flushed out. My understanding is the eGFR needs to remain low over time to really be of concern to your doctor. I say this knowing my mother died 60 years ago (I was 23) with kidney failure - before the days of dialysis. I too watch this portion of my systems for any signs of problems. Recently my eGFR has been low (for 2 years) and I am currently being tested by a Nephrologist to determine if I have a problem and if so what, if anything, can be done. I also have a floating kidney - a kidney that is not tacked up where it belongs, so it floats in my body, causes constant pain, but is also doing 60% of the overall work. This kidney can get pinched and be a major issue - I am 81 and so far it has not caused any major issues, just another item to keep an eye on. Hang in there and try to let the doctors run their tests and make their decisions before getting too concerned. Hard advice for me to follow - so I totally understand.
