I have been having kidney problems since I was 18, I\'m 31 now. I have had kidney stones over 40 times, and currently am passing a stone. I was in the ER last night and they said that I have protein in my urine, my score was 30. What does that number mean? Also, I have a trace of Leukocytes. And my kidney is swollen, I\'m just wondering what the score of 30 means, should I be concerned. Appreciate any help.
