Because the kidneys sit close to the lower back, kidney pain and musculoskeletal back pain can be easy to confuse. Here’s how to tell the two apart.
Where the Pain Is Located
Kidney pain is typically felt higher up, just below the rib cage on one or both sides of the back, rather than in the lower lumbar region where most musculoskeletal back pain occurs.
What Kidney Pain Feels Like
- A deep, constant ache rather than pain that changes with movement
- Pain that may come in waves, especially with kidney stones
- Pain that doesn’t improve with rest or changing position
- Often accompanied by other symptoms (see below)
What Musculoskeletal Back Pain Feels Like
- Pain that worsens with certain movements and improves with rest
- Pain that responds to stretching or changing positions
- Often related to a specific activity, like lifting or twisting
- Typically doesn’t come with fever or urinary changes
Other Symptoms That Point to Kidney Issues
- Fever or chills
- Burning sensation during urination
- Cloudy, dark, or blood-tinged urine
- Nausea or vomiting
- Frequent urge to urinate
Common Causes of Kidney Pain
- Kidney stones
- Kidney infections (pyelonephritis)
- Less commonly, kidney cysts or other structural issues
When to Seek Medical Care
Seek prompt medical attention if you have back pain accompanied by fever, urinary symptoms, or significant nausea — these suggest a kidney issue rather than simple muscle strain, and may require timely treatment.
The Bottom Line
While both kidney issues and musculoskeletal problems can cause back pain, the location, consistency, and accompanying symptoms can help distinguish between them — and guide whether you need urgent medical evaluation.
