Suddenly out of the blue my mum become totally outif breath. X-rays showed that her right lung is badly infected......the nefrologist said that her kidneys were the cause.....creatinine level is 3.7....so he said that only about 11 percent of her one kidney is working . So what are her chances. She has no swelling...no problem with passing urine.....her appetite is good she is not diabetic.....the pain in her chest is better.
