When to see a doctor

By Mayo Clinic Staff

Call your doctor for a same-day appointment if:

  • You have constant, dull, one-sided pain in your back or side
  • You have fever, body aches and fatigue
  • You've had a recent urinary tract infection

Seek emergency care if you develop sudden, severe kidney pain, with or without blood in your urine.
