Flank pain is pain on the side of the back just below the rib cage and above the waist. It can be on one or both sides. Flank pain has many possible causes, including a kidney stone, a urinary tract infection, or back strain.
Flank pain may get better on its own. But don't ignore new symptoms, such as fever, nausea and vomiting, urination problems, pain that gets worse, and dizziness. These may be signs of a more serious problem. You may have to have tests or other treatment.
