Kidney pain : When to see a doctor?

Call your doctor for a same-day appointment if:

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

Seek emergency care if you develop sudden, severe kidney pain, with or without blood in your urine. This could mean you have a problem with the blood circulation in your kidneys, such as a blood clot or hemorrhage, and it's important to have it evaluated right away.
