Hello, Kidney infection can cause your symptoms like colicky pain, fever, chills, and rigors, abdominal discomfort etcetera. If you have insurance get an ultrasound abdomen done to rule out any anomaly is there in the abdomen if any of these above symptoms persist. If there is urinary tract infection you might get burning micturition, frequency, urgency, dribbling, etcetera all will be ruled out by an ultrasound scan. If no symptoms persist it s better not to worry much and take care of your health rather than unnecessary testing for simply having insurance. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Archana
