I wrote a new article for empowher.com called Chronic Kidney Disease -- Watching Out for the Signs. Some of us have less than healthy kidneys, I for one used to have kidney infections like clock work every winter when I was a kid. And some of the symptoms listed here are things I deal with or have dealt with in the recent past. Numbness, fluid retention, itchiness, cramping muscles, fatigue ... I don't know if that tells me there's been something wrong with my kidneys. Lots of conditions can cause similar symptoms. But it got my attention.
