A typical Urinary Tract Infection (UTI) primarily affects the bladder and urethra, causing discomfort localized to the pelvic area. However, if left untreated, a UTI can progress to the kidney, which may cause back pain. 

While a simple UTI typically does not directly lead to lower back pain, it’s important to recognize kidney infection symptoms, such as fever and flank pain. 

This article will look into the connection between UTIs and back pain, discussing causes and treatment options, so read on.

Can UTIs cause back pain?

Yes, UTIs can cause back pain. When bacteria travel up the urinary tract, they can reach the kidneys, leading to inflammation and discomfort in the flank area (sides of the lower back). 

This can be a warning sign of a more serious complication: a kidney infection known as Pyelonephritis. In Pyelonephritis, bacteria infect the kidneys, causing various symptoms, including lower back pain. The kidneys, located just below the ribcage at the back, are particularly vulnerable to infection when bacteria reach this area.

Therefore, if you experience persistent or severe back pain along with symptoms like nausea and fever, it could indicate that the UTI has progressed to a kidney infection.

Warning
A kidney infection is a serious condition requiring prompt attention. If left untreated or not treated properly, it can cause many health complications, including kidney failure.

UTI back pain often presents alongside additional characteristics. Here’s what you should know:

  • Location: The pain is typically observed in the lower back, just above the waistline. It may radiate to the sides or lower abdomen due to the location of the kidney
  • Type of pain: It is often described as a dull, aching discomfort. It may feel like a constant, nagging ache in the lower back
  • Severity: The intensity of UTI-related back pain can vary from mild to moderate. In some cases, it can be quite uncomfortable but is usually not as severe as kidney pain caused by conditions like kidney stones
  • Accompanying UTI symptoms: It is typically accompanied by other symptoms. This includes a frequent urge to urinate, high temperature, shivering, fatigue, loss of appetite, and diarrhea

Fact
Pregnant women are at an increased risk of UTIs, including kidney infections. Hormonal changes in pregnancy can slow down the flow of urine and relax the urinary tract muscles, making it easier for bacteria to ascend from the bladder to the kidneys.

Treatment of UTI and back pain

Treating the infection is key to relieving UTI-related back pain and preventing complications. Timely treatment helps address the root cause and eases discomfort. So, it’s important to see a doctor promptly and follow treatment instructions to manage UTIs effectively and avoid problems. Common approaches to treating UTI-related back pain:

Antibiotics

Kidney infections are treated with a course of antibiotics prescribed by a healthcare provider, such as Augmentin (Augmentin 375 mg), Amoxicillin, or Trimethoprim-sulfamethoxazole (TMP-SMX). These medications help eliminate the underlying bacterial infection and alleviate associated symptoms, including back pain. 

Pain management

Over-the-counter pain relievers, like Ibuprofen (Brufen 400mg) or Acetaminophen, help in managing the discomfort associated with UTI-related back pain.

Hydration

Drinking plenty of water flushes out the harmful bacteria from the urinary tract and may alleviate symptoms. Staying well-hydrated is crucial during UTI treatment.

Rest

Resting and avoiding strenuous activities can help your body recover quickly from the infection, as kidney infections can be physically draining.

Conclusion

When a UTI spreads to the kidneys, it causes a kidney infection known as Pyelonephritis, a serious medical condition associated with lower back pain.

Recognizing the characteristics of UTI-related back pain—such as its location, type, severity, and accompanying UTI symptoms—is essential for proper diagnosis and timely treatment. UTIs should not be taken lightly, as they can lead to severe complications if left untreated.

Treatment for UTI back pain primarily involves antibiotics to eliminate the underlying infection. Other treatment options include pain management with over-the-counter medications, staying well-hydrated, and allowing your body to rest and recover.

It’s important to seek timely medical attention to prevent the UTI infection from advancing to the kidneys and leading to lower back pain. Early intervention can help prevent the infection from progressing and promote a quicker recovery. If you suspect a UTI or experience back pain along with other urinary symptoms, it’s important to consult a healthcare professional for accurate evaluation and appropriate treatment.

Frequently Asked Questions

Where does your back hurt with a UTI?

Back pain with a UTI is typically felt in the lower back, just above the waistline. The infection may also extend to the sides or lower abdomen if it reaches the kidneys. This discomfort in the lower back is often described as a dull, aching sensation.

Is back pain with a UTI serious?

Back pain associated with a UTI can be serious if it progresses to kidney infection, known as Pyelonephritis. If left untreated, kidney infections can culminate in severe health complications, including kidney failure. Therefore, it is crucial to seek medical attention promptly if you experience back pain.

How can I tell if my back pain is kidney-related?

Watch out for additional symptoms to determine if your back pain is kidney-related. These symptoms include fever, nausea, vomiting, and pain that feels deep in the flank area, which is on the side of the lower back near the ribs. These symptoms indicate a kidney infection. 

How fast can a UTI go to the kidneys?

If the initial condition is not treated promptly, a UTI can become a kidney infection within a few hours and days. Addressing a UTI early with appropriate medical intervention, usually antibiotics, is essential to prevent the disease from reaching the kidneys and causing severe health issues.

Can a UTI spread to your spine?

Yes, a UTI can spread to the spine, causing Osteomyelitis. This rare but serious complication occurs when bacteria from the urinary tract travel to the spine, infecting its bones. Medical reports confirm this risk, emphasizing UTIs’ potential to lead to spinal issues.
