Las night I had an achy, painful back. This morning it hurts to wee, and I feel out of sorts (a bit sick, but not bad, mostly just feel 'weird' and not quite myself). When I wipe after going to the toilet there is definitely a bit of blood. I've never had a UTI before. Is there anything I can do to help feel better? I'm supposed to be going out for a meal tonight with some friends (which I hardly ever do so don't want to cancel!)
