I recently had a physical and need to go back to recheck my right kidney.I am feeling discomfort in my lower back and light cramps in lower stomach area.I had been drinking plenty of water because of menopause,hot flashes and nightsweats.I am pretty sure it is because I over drank too much water and now my right kidney is failing me.I am urinating alot but no signs of bladder infection, just urinating night and day and feeling low energy and concentration is not well. I will be going back to Drs' in Nov to do another ultrsound. What do you think?
