Hippi is right, urine that looks like foamy beer is a defintie sign of protein in your urine, and protein loss over time does cause kidney damage. It is also possible you have a kidney infection with the kidney pain and blood in your urine. (Kidney disease itself is NOT painful.) You need to have your urine checked, if not by a nephrologist, at least by your PCP. Please let us know how you make out.
