Seek immediate medical attention if you experience fever above 101°F (38.3°C), chills, severe flank pain (pain in your side, below your ribs), nausea and vomiting, or blood in your urine. These symptoms suggest a serious infection requiring prompt treatment.
Don’t delay seeking care if you notice:
- Persistent pain in your lower back or side that doesn’t improve with over-the-counter pain relievers. Frequent, urgent urination with burning or pain. Cloudy or foul-smelling urine. Fatigue and weakness persisting for more than a couple of days.
While some mild kidney infections might improve with home care (such as increased fluid intake and rest), a doctor’s visit is necessary to confirm the diagnosis and rule out complications. They can provide accurate diagnosis, prescribe appropriate antibiotics, and monitor your progress to prevent long-term kidney damage.
Kidney infections are dangerous if left untreated. Early diagnosis and treatment are vital for preventing potentially severe complications like sepsis (a life-threatening condition) and permanent kidney damage. Your doctor will help determine the best course of action for your individual situation.
Contact your doctor or go to urgent care if you experience any of the above symptoms. Follow your doctor’s instructions carefully regarding medication and follow-up appointments. Complete the full course of prescribed antibiotics, even if you start feeling better.
