Signs & Symptoms
Common sign and symptoms of a kidney infection include fever, chills, back, side (flank) or groin pain, abdominal pain, frequent urination, a strong and persistent urge to urinate, burning or pain when urinating, nausea and vomiting, hematuria which is pus or blood in the urine, and urine that smells bad and is cloudy. If an individual shows any of these symptoms and is worried a kidney infection has developed, they should make an appointment with their doctor immediately, especially if they are being treated for a UTI and it is not improving.
A severe kidney infection can lead to life-threatening complications such as kidney damage or blood poisoning. A patient who has these common symptoms combined with bloody urine or nausea and vomiting should visit their local hospital immediately as well. Also, if a woman is pregnant, seeking medical attention is necessary, as a kidney infection can affect the baby's health.
