Go to the emergency room or call emergency services immediately if you experience severe symptoms such as high fever (over 104°F or 40°C), chills, severe back pain, and/or difficulty urinating. These could signal a serious kidney infection complication needing urgent care.
Other Warning Signs Requiring Prompt Medical Attention
Seek medical attention within 24 hours if you notice any significant worsening of your symptoms, including increased pain, nausea and vomiting that prevent you from keeping down fluids, or blood in your urine. Persistent, debilitating fatigue also warrants a doctor’s visit.
Remember, prompt medical care is vital for effective treatment and to prevent potential complications. Don’t hesitate to contact your doctor if you have any concerns.
