GFR dropped 5 more points and I don't know why.

My eGFR dropped from 50-55 to 36-41 in 6 months. I cite two tests because I drink more water and have a second test each time.

I have never seen a nephrologist and my doc misread the repeat tests of 36 and 41 in one week, to being over longer time and wrote me things were "stable."

I made an appointment with a nephrologist. I have systemic lupus that has never manifested with organ damage, was treated for breast cancer, my blood sugars are somewhat erratic (I am very thin). and I am on Tymlos for osteoporosis, a med that can cause kidney stones from high calcium but does not seem to cause kidney damage. I occasionally take flurpriprofen an NSAID. but very rarely.

The drop is significant and mysterious. I need to ask about my next bone med, Reclast (endo will do 20% dose to start), contrast with imaging, and dose of Paxlovid if needed. And what meds to avoid.
