@jeffh ~ So glad you are feeling a bit more at ease. I asked my Primary if she would refer me to a nephrologist. She told me she could handle my case, being that I'm only a Stage 3a at this time. So, I asked the Urology PA I'm working with (for Interstitial Cystitis) if she would refer me. She thought that might be a good idea and sent a request to a local nephrologist who had been recommended by a dietician I once saw. My point is that if you believe you would feel better seeing a specialist, you may need to advocate for yourself and push the issue. Good luck!
