@hello1234 Hi- I used Fluoricil. They are actually the same thingjust one ia a generic and the other is a brand name. At my age my memory isn't what it used to be, but I think it pretty much cleared up in 2 weeks but was more like a month to really completely vanish. But be warned that the first thing that happened to me was that it got much worse. Not in severity but what was just a few spots spread all over my head when I applied the cream all over. I was prescribed the cream not the liquid and I'm not sure what's the difference is. I was working with a dermatologist whom I trusted to know what to do and she did. None of it was all that bad, just mildly uncomfortable and a bit annoying for a couple of weeks but i you've had CKD for a while you are used to it I'm sure.. Nothing to be afraid of as far as I'm concerned. You can handle this one.
