When to see a doctor

By Mayo Clinic Staff

Call your health care provider right away if you feel constant, dull, one-sided pain in your back or side. Ask for a same-day appointment if you also:

  • Have fever, body aches and fatigue.
  • Had a recent urinary tract infection.
  • Feel pain when you pee.
  • See blood in your urine.
  • Have an upset stomach or vomiting.

Get emergency care if you have sudden, serious kidney pain, with or without blood in your urine.
