Yes, you should seek medical attention for a kidney infection (pyelonephritis) if you experience severe flank pain, high fever, chills, persistent nausea, vomiting, or urinary symptoms that worsen after a standard urinary tract infection. A kidney infection is a serious bacterial condition that starts in the bladder and travels upward, requiring prompt medical evaluation, laboratory testing, and targeted antibiotic therapy to prevent permanent renal damage or dangerous bloodstream infections.
However, kidney infections accompanied by extreme confusion, dangerously low blood pressure, or signs of severe sepsis require immediate emergency room hospitalization. At Sahara West Urgent Care, our clinical team evaluates systemic symptoms, performs urgent on-site diagnostic testing, and provides rapid outpatient treatment for moderate upper urinary tract infections.
Common Signs and Symptoms of Pyelonephritis
Urgent care providers frequently diagnose and manage acute kidney infections and advanced urinary complications, including:
-
Severe Flank & Lower Back Pain: Deep, persistent pain or tenderness in your back, side, or ribs directly over the affected kidney.
-
High Fever and Chills: Systemic inflammatory responses resulting in elevated body temperatures, sweating, and shaking chills.
-
Persistent Nausea and Vomiting: Gastrointestinal upset triggered by severe infection toxicity and localized pain.
-
Progressive Urinary Symptoms: Worsening burning sensations, painful urination, or foul-smelling, cloudy urine.
-
Fatigue and General Malaise: Extreme physical exhaustion, weakness, and body aches accompanying the systemic bacterial spread.
The Diagnostic Process: Why an Exam is Required
You cannot safely treat a suspected kidney infection at home or manage it without professional medical diagnostics. To confirm a pyelonephritis diagnosis and prevent complications, our medical team at Sahara West Urgent Care performs:
-
Urinalysis and Urine Culture: Checking urine samples for high concentrations of white blood cells, red blood cells, and targeted bacterial growth.
-
Comprehensive Vital Signs Check: Evaluating blood pressure, heart rate, and temperature to assess for systemic shock or high fever risks.
-
Physical & Abdominal Assessment: Examining flank tenderness, costovertebral angle (CVA) pain, and abdominal rigidity.
-
Targeted Antibiotic Strategy: Prescribing strong, evidence-based oral antibiotic regimens tailored to eliminate upper urinary tract bacterial pathogens.
