Signs and symptoms of urinary infections (UTIs) are burning when you urinate, and urgency and/or frequency of urinating. As the infection progresses, you could develop back pain, nausea, vomiting and fever—all serious signs that it's past time to see your doctor!

The symptoms that a urinary tract infection causes depend, to some degree, on the specific location in the urinary tract that the infection has occurred. Most symptomatic urinary tract infections involve the bladder and, as such, can also be termed cystitis. Typical symptoms of lower urinary tract infections are pain or burning with urination, frequent urination, hesitancy on urination, blood in the urine, lower abdominal pain or discomfort. Infections involving the kidneys are less common but more severe. Typical symptoms of upper urinary tract infections include fever, chills, back pain, side pain, abdominal pain, and nausea with or without vomiting.

With urinary tract infections (UTIs), some people have no symptoms, but most have one or more of the following:

  • an urgent need to urinate, often with only a few drops of urine that pass
  • a burning feeling when they urinate
  • cloudy urine or some blood in their urine
  • strong odor to the urine

If the infection spreads to the kidneys and becomes more severe, it may cause pain in the lower back as well as fever, chills, nausea and vomiting. See your doctor immediately if you have any of these symptoms.

The symptoms of a urinary tract infection can be urinary frequency, urinary burning and fever.

A urinary tract infection (UTI) causes moderate pain in the lower abdominal region when you urinate. Other symptoms of a UTI include blood in the urine, nausea, vomiting, fever, chills, and fatigue.
