3 min read 13-03-2025

Flank pain, that sharp, aching, or throbbing sensation in your side, can be a real nuisance. But pinpointing its exact location is crucial for diagnosis. This article will help you understand where flank pain is located and explore the potential causes behind it. Knowing the location and characteristics of your pain can help your doctor determine the underlying issue.

Understanding Flank Pain Location

The flanks are the areas on either side of your back, between your ribs and your hips. Flank pain can occur on one or both sides. It's important to note that the sensation can radiate or spread, making it feel like it originates from a different area, such as your lower back, abdomen, or even groin.

Pinpointing the Pain

To accurately describe your flank pain, consider these points:

Specific Side: Is the pain on your right side, left side, or both?
Intensity: Is it a mild ache, a sharp stabbing pain, or a dull throbbing?
Duration: Is it constant, intermittent, or does it come and go?
Radiating Pain: Does the pain spread to other areas like your back, abdomen, or groin?
Accompanying Symptoms: Are there other symptoms present, such as fever, nausea, vomiting, or changes in urination?

Common Causes of Flank Pain

Many conditions can cause flank pain. Some of the most common include:

1. Kidney Infections (Pyelonephritis)

Kidney infections are a frequent cause of flank pain, often accompanied by fever, chills, nausea, vomiting, and painful urination (dysuria). The pain is typically localized to the affected kidney area (usually one side). This infection requires prompt medical attention.

2. Kidney Stones

Kidney stones are hard deposits that form in the kidneys. They can cause excruciating flank pain, often described as a wave-like or cramping sensation. The pain may radiate to the groin or lower abdomen. Kidney stones may pass on their own, but medical intervention is often necessary.

3. Muscle Strain or Injury

Overexertion, lifting heavy objects, or sudden movements can strain the muscles in your flank area. This strain can lead to sharp, localized pain that worsens with movement. Rest and over-the-counter pain relievers often help.

4. Appendicitis

While typically associated with lower right abdominal pain, appendicitis can sometimes present with flank pain, especially in atypical cases. Other symptoms include nausea, vomiting, fever, and loss of appetite. This requires immediate medical attention.

5. Pancreatitis

Inflammation of the pancreas can also cause flank pain, often radiating to the back. Other symptoms include severe abdominal pain, nausea, vomiting, and fever. Pancreatitis is a serious condition requiring urgent medical care.

6. Diverticulitis

Inflammation or infection of small pouches (diverticula) in the digestive tract can result in flank pain, usually accompanied by abdominal pain, fever, nausea, and changes in bowel habits. Treatment depends on the severity of the condition.

7. Ovarian Cysts (Women)

Women may experience flank pain associated with ovarian cysts, particularly if the cyst ruptures or twists. Other symptoms can include pelvic pain, irregular menstrual cycles, and abdominal bloating. Medical evaluation is important.

8. Other Less Common Causes

Other less frequent causes of flank pain include:

Costochondritis: Inflammation of the cartilage connecting the ribs to the breastbone.
Spinal problems: Conditions affecting the spine, such as degenerative disc disease or herniated discs.
Pneumonia: Lung infection sometimes radiating pain to the flank.
Gynecological issues: Endometriosis, pelvic inflammatory disease.
Abdominal aortic aneurysm: A life-threatening condition requiring immediate medical attention.

When to See a Doctor

Seek immediate medical attention if your flank pain is:

Severe or sudden
Accompanied by fever, chills, or nausea
Associated with blood in your urine
Radiating to the groin or lower abdomen
Persistent and worsening

Diagnosis and Treatment

Your doctor will perform a physical exam and likely order tests, such as a urine test, blood test, imaging studies (ultrasound, CT scan, X-ray), to determine the cause of your flank pain. Treatment will vary depending on the underlying condition and may involve medication, surgery, or other interventions.
