Kidney pain

Pain in your kidney area can be caused by many different problems. If you have pain in your kidney area, please see your doctor.

The pain may be a sign of kidney infection, a kidney stone or something else completely.

What is kidney pain

Kidney pain, or renal pain, is usually felt in your back (under the ribs, to the right or left of the spine). It can spread to other areas, like the sides, abdomen or groin.

Kidney pain location

You have two kidneys that are located just above the waist between the levels of the last thoracic vertebrae T12 and third lumbar (L3) vertebrae, a position where they are partially protected by ribs 11 and 12. If these lower ribs are fractured, they can puncture the kidneys and cause significant, even life-threatening damage. The right kidney is slightly lower than the left (see Figure 1) because the liver occupies considerable space on the right side superior to the kidney.

What causes kidney pain

Your Kidneys drain urine to the bladder via tubes called ureters. Your bladder is emptied via the urethra. Problems in any of these areas can cause pain, and may be caused by:

  • Kidney stones
  • Kidney infection
  • Other types of kidney disease.

Back pain due to muscle problems is usually in your lower back. Pain due to kidney problems is usually deeper and higher in your back, under your ribs. Signs that it is a kidney problem can also include fever, vomiting, pain in your sides or painful urination.

Pain around your kidneys can also be caused by other problems too, such as:

  • Problems with your spine or ribs
  • Muscle pain
  • Pneumonia: Pneumonia is an infection of the lungs.
  • Problem with your spleen or your liver
  • A hernia. A hernia occurs when tissues or organs bulge through a weak point in the wall of the abdomen (belly muscles).

Kidney pain diagnosis

To diagnose pain in your kidney area, your doctor will talk to you and examine you. You may also be asked to have:

  • blood test
  • urine tests
  • an ultrasound.

Kidney pain treatment

Treatment depends on the cause, the severity of the pain and how sick you are feeling.

You may find the pain eases with simple treatments like paracetamol. Talk to your doctor and your pharmacist.

If you have pain that you are worried may be caused by a kidney problem, please see your doctor.

  • discolored urine, painful urination or blood in your urine
  • feeling that you need to urinate urgently
  • a temperature
  • the appearance of gravel (small kidney stones) in your urine
