I've had an on/off UTI for just under 3 weeks now (confirmed by pharmacist dipping my urine and found traces of infection and blood. I stupidly tried to manage initially by just drinking lots of water because I have a fear of taking medication - symptoms disappeared for a few days so I thought I'd successfully got rid of it, then they came back. I decided earlier this week to take the medication I was given, symptoms disappeared within 2 days so I stopped. However this morning symptoms are back again. So I am now taking the rest of the medication. However, I now have pink tinged urine (I assume blood?), lower back pain on and off (mild and not excruciating), and still feel like I am peeing glass. I am shivering on and off and feel very fatigued. Also nauseous and no appetite. Partner wants me to go to a&e in case it's now a kidney infection, but I am wanting to stay home as need to be comfortable (which I am lying in bed) and really don't need to spend my afternoon sitting in a&e for hours. I want to finish the course of antibiotics and see if it helps first. I'm unsure why I'm posting. Mainly to see if my symptoms sound serious enough to possibly be a kidney infection or could it just be the UTI still?? I don't want to waste anyone's time at a&e.
