Gfr level 58. Fatigue, muscle pain, headache, flank pain. Is this really serious or can my GFR go back up? Also ankle swelling. I don't have a pcp yet.

In brief: Unreliable

I'd be concerned about a kidney infection.
These estimated gfr's derived from spot creatinines are subscientific -- there's even an adjustment "because people of african descent are more muscular" -- and i'd both you and your physician to focus on how you look and feel rather than on numbers that are at best intended as guides.
