Hi my Grandfather has been suffering with a urin infection for the last 2 years, so they say but today he had blood in his urin, but later on in the evening he needed the toilet again but at this time it seemed that it was just like pure blood, and was coming out for quit some time. He has only one kidney left as he had one removed just over 10 years ago, he has no temp or pain, but has gone off his food a little, if you could give me your thoughts that would be great, i have the thoughts on what it could be, thank you for your time.
