Sir I had done urine test routine I had 2 to 3 plus cells and trace of albumin in it .. I did urine test because I had back pain and  brown urine color and a bit of burning sensation near tip of male part after urinating .. then I started drinking water about 3 to 4 litres a day and I was okay after that for 2 to 3 days my back pain went away and urine was clear no burning sensation .. now after 3 days I have a bit of back pain and brown colour urine and a bit burning sensation.. what do I need to do ? Please help any medication ? Pls recommend.
