This year I have experienced an actual renal symptom. At least I want to ask you if it is. Pain, which doesn't last more than a few minutes, in my right flank - sort of at the top of one side of the buttocks, a little higher. I get this occasionally when I stand up after sitting down. Is that kidney pain do you think? Does it indicate I am getting worse? I know you don't diagnose, obviously, but you could describe kidney pain. I am GFR58. Thanks.
