The idea behind this forum is to learn and share from our experiences. The one that continues to help all of us constantly is @gingerw, our mentor. She has experienced so much, and has offered so much sound advice. When she says to follow the trend of lab results, she means it. I went from an eGFR of 45(stage 3A) to 18(stage 4) in less than 3 months, because I was dehydrated. My Mayo NP nephrologist prescribed a diuretic "Torsemide" for me. My endocrinologist later prescribed a diabetic and diuretic dose of "Farxiga", and my eGFR started to fall again so I stopped that as well. When you get dehydrated, your eGFR goes down quickly. There is a possibility that happened to you, but I am far from being your doctor or trying to diagnose you. What Ginger says about the trend of your labs is so important, and that you must make decisions and consult that information with your doctor. In my case as a college computer science teacher, I gave my docs spreadsheets showing the downward trend of the 2 medications based on eGFR, and they were both convinced that I was right. Lastly, nephrology people are so busy helping those in Stage 4 thru dialysis, it sometimes is difficult seeing them on a regular basis, and those at stage 3 to stage 1 can be vulnerable to 6 months or longer wait times. Thus, perhaps the non urgency with you. There truly is an epidemic of kidney disease, and having a team of docs including a dietitian, an acupuncturist, an endocrinologist, a nephrologist, a PCP , a great Mayo mentor, and many others here give you the best shot.
