Thankyou so much. I ended up ringing the after hours line around 7 45 am. They had a good talk to me and arranged for a doctor to ring me back. He told me to go to the hospital where there is a doctor's surgery. It was a Sunday so everywhere else was shut. The doctor tested my water where he found blood in it although you were unable to see it. He gave me some Trimethoprim tablets, just 6 and I had to take them twice a day. I have now got to go to my own surgery this afternoon for my water to be tested again to make sure all the blood has gone.
My test was clear of blood and blood sugar was ok. My doctor is sending a further water sample away to see if there is any further problem. Thankyou so much for your help.
