Can a UTI Cause Severe Back Pain?

Severe Back Pain

Yes, a urinary tract infection (UTI) can cause severe back pain in some cases. When a UTI progresses or becomes more severe, it can lead to a condition called pyelonephritis, which is an infection of the kidneys. Pyelonephritis can cause significant pain in the lower back or sides of the abdomen, where the kidneys are located.

Here’s how a UTI can lead to severe back pain:

  • Kidney Involvement: If bacteria from a UTI travel up the urinary tract and reach the kidneys, they can cause an infection in the kidney tissue. This condition, known as pyelonephritis, often results in severe back pain, typically felt on one or both sides of the lower back or abdomen.
  • Inflammation and Pressure: The infection and inflammation in the kidneys can lead to swelling, which puts pressure on surrounding tissues and structures, including nerves. This pressure can cause significant pain in the affected area.
  • Other Symptoms: Along with severe back pain, pyelonephritis can cause other symptoms such as fever, chills, nausea, vomiting, and urinary symptoms like frequent urination, urgency, and pain or burning during urination.

If you’re experiencing severe back pain along with symptoms of a UTI, such as burning during urination or urinary urgency, it’s essential to seek medical attention promptly. Pyelonephritis can be a serious condition requiring treatment with antibiotics to prevent complications such as kidney damage or bloodstream infections. Your healthcare provider can perform tests to diagnose the UTI and determine if kidney involvement is present, and prescribe appropriate treatment to address the infection and alleviate your symptoms.
