<s>[INST] Symptoms [/INST] When you have a UTI, the lining of the bladder and urethra become red and irritated just as your throat does when you have a cold. The irritation can cause pain in your lower abdomen or pelvic area and even lower back, and will usually make you feel like urinating more often. Burning or pain when urinating is the most common symptom. You may even feel a strong urge or need to urinate but only get a few drops. This is because the bladder is so irritated that it makes you feel like you have to urinate, even when you don't have much urine in your bladder. At times, you may lose control and leak urine. You may also find that your urine smells bad and is cloudy.

Kidney infections often cause fevers and upper back pain - usually on one side or the other. Kidney infections may also often cause nausea and vomiting. These infections need to be treated at once because a kidney infection can spread into the bloodstream and cause a life-threatening health issue.
