What are the symptoms of a UTI?

Here are some symptoms you may experience with a UTI: Needing to pee more frequently, suddenly, or more urgently than usual. Pain or a burning sensation when peeing. Needing to pee at night more often than usual. New pain in the lower tummy. New incontinence or wetting yourself that is worse than usual. Kidney pain or pain in the lower back. Blood in the pee. Changes in behaviour such as acting agitated or confused (delirium). This could be a symptom of a UTI but could also be due to other causes, which need to be ruled out.
General signs of infection, like a fever, high temperature or feeling hot and shivery, with shaking (rigors) or chills. 
A very low temperature below 36 degree C. You may experience fewer of these symptoms if you have a urinary catheter.
