flank pain 통증

Flank pain is a common symptom that refers to discomfort or pain in the side or back, between the lower ribs and the pelvis. This type of pain can range from mild to severe and may be a sign of an underlying medical condition. In this blog post, we will explore the various causes of flank pain, its symptoms, and the available treatment options.

Kidney Stones: A Common Culprit

One of the most common causes of flank pain is the formation of kidney stones. These small, hard deposits develop in the kidneys and can cause intense pain when they pass through the urinary tract. The pain is typically felt on one side of the back or abdomen and may be accompanied by blood in the urine or a frequent urge to urinate. Treatment for kidney stones may involve medications to manage pain or procedures to remove or break down the stones.

Urinary Tract Infections: More than Just an Inconvenience

Urinary tract infections (UTIs) are another possible cause of flank pain. These infections occur when bacteria enter the urethra and multiply in the urinary tract. Alongside flank pain, individuals with UTIs often experience a burning sensation during urination, frequent urination, and cloudy or blood-tinged urine. Antibiotics are commonly prescribed to treat UTIs and alleviate the associated pain.

Musculoskeletal Problems: Not to Be Ignored

Sometimes, flank pain can be attributed to musculoskeletal problems, such as muscle strains or injuries to the ribs. These issues can cause localized pain in the flank area, which may worsen with movement or deep breathing. Rest, applying heat or ice, and over-the-counter pain medications are often recommended to manage musculoskeletal-related flank pain.

Renal Disorders: A Deeper Concern

Certain renal disorders can manifest as flank pain. Conditions like pyelonephritis (kidney infection) or polycystic kidney disease can cause persistent or recurrent pain in the flanks. In addition to the pain, individuals may experience fever, nausea, and changes in urinary habits. Treatment for these conditions typically involves addressing the underlying cause and managing the symptoms with medications.


Flank pain is a common complaint that can have various causes, ranging from kidney stones to musculoskeletal problems. It is important to seek medical evaluation for persistent or severe flank pain, as it may indicate an underlying condition that requires treatment. The treatment options will depend on the cause of the pain, but may include medications, lifestyle changes, or other interventions. Remember, early identification and management of flank pain can help alleviate discomfort and prevent potential complications.
