Flank Pain


Flank pain

is felt in the area below your ribcage and above your hip bones, often in the lower back. Your pain may be dull or so severe that you cannot get comfortable. The pain may stay in one area or radiate to another area. It may worsen and lighten in waves. Flank pain is often a sign of problems with your urinary tract, such as a kidney stone or infection.

Seek care immediately if:

  • You have a fever.
  • Your heart is fluttering or jumping.
  • You see blood in your urine.
  • Your pain radiates into your lower abdomen and genital area.
  • You have intense pain in your low back next to your spine.
  • You are much more tired than usual and have no desire to eat.
  • You have a headache and your muscles jerk.

Contact your healthcare provider if:

  • You have an upset stomach and are vomiting.
  • You have to urinate more often, and with urgency.
  • Your pain worsens or does not improve, and you cannot get comfortable.
  • You pass a stone when you urinate.
  • You have questions or concerns about your condition or care.

Treatment for flank pain

may include medicine to decrease pain or treat a bacterial infection.
