Kidney infections usually stem from a urinary tract infection (UTI). A serious UTI can travel toward the kidneys, and cause the kidney and ureters to become inflamed and infected. A kidney infection should be treated as soon as it is noticed to avoid permanent damage. Symptoms might mimic that of a urinary tract infection.
Pain
Back and stomach pain are consistent with kidney infections. The discomfort might extend to the side of the body or the groin in some people.
Fever
One of the signs of a kidney infection is a fever that reaches 102 degrees F or higher. People who have developed a kidney infection usually run a high fever for at least two days, according to the National Institutes of Health (NIH).
Urinary Symptoms
Signs of a kidney infection include a series of urinary symptoms. Frequent urination might be noted as a person might experience pain, or there's burning or stinging when urinating. Urine might smell unpleasant, or contain blood or pus.
Skin Changes
Kidney infection symptoms include several changes in the color and temperature of the skin. A person's skin might appear to be flushed or red in color. The skin might seem abnormally warm or moist when touched.
Fatigue
Feeling more tired than normal can be a sign of kidney infection.
