<s>[INST] What are common symptoms of a UTI? [/INST] Symptoms of a urinary tract infection (UTI) vary by location. Patients may have one or a combination of the following:

In the lower urinary tract (the most common area for UTIs): burning during urination, an urgent need to urinate frequently although not much urine comes out, cloudy urine, strong smelling urine, pain in the lower abdomen, and blood in the urine.
In the upper urinary tract: fever, chills, nausea, vomiting, lower back pain, and occasionally the symptoms of lower tract infection.
It is possible to have some of the above symptoms and not have a UTI. Some women have a UTI and no symptoms at all, which is called asymptomatic bacteriuria. Source: THE WOMEN'S HEALTH PAVILION.
