My doctor never told me that us cfers can get kidney stones from cf. I just wanted to remind you all to drink lots of water to avoid what I am dealing with. I have a 1cm stone in my kidney, which is huge. I did the ultra sonic waves surgery 2 weeks ago and the stone didnt break up. They put me under for 2 hours and when I woke up from surgery, I was coughing like crazy. I have a doc apt tomorrow to see what the next round is, Im sure another surgery, but this kidney stone is getting the best of me.
