A member asked:

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.

A doctor has provided 1 answer

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.
