Back Pain and Flank Pain
It is sometimes hard to tell the difference between back pain that is caused by a bone or muscle problem and back pain (flank pain) that is caused by a kidney or bladder infection or a kidney stone.
Back pain that is caused by a bone or muscle problem:
- Occurs in the lower back, below the waist, or in the upper back, over the spine or between the shoulder blades.
- Gets worse when a person moves.
- Gets better when a person rests.
Flank pain that is caused by a kidney infection or a kidney stone:
- Occurs on one side of the back, just below the rib cage (above the waist).
- May spread to the bladder area or genitals.
- Gets worse as the bladder fills.
- Does not get worse when a person moves.
Flank pain with fever and urinary symptoms may mean a kidney infection (pyelonephritis) is present.
