I went to see the doc and had to do a urine sample, I had been to the gym just before and had been drinking lots of water, my urine was the colour of water, the results came back as clear, but could this have been because the urine was so diluted by the amount of water I had been drinking?
No, drinking water might affect the specific gravity (denseness) at your urine, but they would have been looking for sugar, blood or protein which would not have been affected by your drinking.
the doc felt around the kidneys and they felt a bit tender, obviously this is what I told her, she only suggested the urine sample, will go back though if there is no improvement in a couple of days
