Flank pain is defined as discomfort in the upper abdomen, back, or sides. It appears in the area between the ribs and the pelvic bone. The discomfort is usually worse on one side of your body than the other. Flank pain location includes both sides of the lower back, between the pelvis and the ribs. These regions constitute the flank area. A variety of illnesses, disorders, and accidents may cause flank pain. Infection, kidney stones, or muscle strains are common causes of left flank pain. Rest, pain medication and antibiotics may be used to treat flank discomfort depending on the cause.

Most people will have some degree of flank pain at some time in their life, and it will nearly always be minor. While minor flank pain is not dangerous, persistent or severe flank pain may signal a significant medical issue such as dehydration or a urinary tract infection. Kidney stones or any kind of renal illness may cause persistent right flank pain.

Flank pain may range in intensity from mild to severe. This kind of pain may be severe or little, and it can occur at any moment. It often affects just one side of the body, but both sides may be affected at the same time. Renal problems are one of the most common causes of flank pain. Back pain may also cause flank pain, which starts in the spine and spreads outward.

Your healthcare provider will examine by gently touching his or her fingers on the sensitive area. They will want to know where you’re experiencing discomfort and if it improves or worsens with particular activities. A variety of tests may be ordered by your doctor to search for signs of kidney stones, infection, damage, or sickness.


There are a variety of causes of flank pain. Some are listed below:

UTI Problems: Numerous urinary tract infections i.e. UTIs, including kidney as well as bladder infections, may cause severe flank pain. Fever, chills, bloating, vomiting, and blood in the urine, among other symptoms, are all frequent indications of infection and urethral blockages (such as kidney stones). Dehydration may induce urinary tract problems, which can cause flank pain.

Back Problems: Lower back discomfort may be caused by a variety of illnesses, including arthritis, fractures, and anatomical abnormalities of the spine. A herniated disc, degenerative disc or pinched nerve degeneration may all cause flank discomfort. Muscle spasms in the flank or lower back are common after a severe strain.

Disease Conditions: Gallbladder disease, kidney malignancy, liver disease, and certain gastrointestinal diseases may also produce flank pain. The most frequent cause of flank discomfort is gallbladder disease. Pain in the flanks may be an indication of renal artery disease, which develops when blood flow to the kidneys is obstructed.

Shingles: It is a virus-caused illness-causing side pain. A painful rash on one side of the trunk is one of the first signs of shingles and is the reason why your side hurts.

Aneurysm: Pain on both sides of the lower abdomen may be caused due to aneurysm. The lower aorta i.e. the major blood artery that transports blood out from the heart has the ability to expand and widen. If it gets to a particular size, it may explode. An aortic aneurysm in the abdomen causes pain and discomfort in the flank area.

When to see a doctor

If you are suffering flank discomfort, make an appointment with your doctor. It is crucial to see a doctor if it does not disappear within a day, or if it vanishes and then reappears. If you have flank discomfort in addition to other symptoms, this may indicate a more severe health issue. If you have flank discomfort with the following symptoms, contact your doctor right away:

·         Blood in urine, or pain while peeing

·         Diarrhea, constipation, and bloating

·         Fever, chills, and dizziness

·         Urinary incontinence i.e. the inability to urinate on a regular basis

·         Headaches

·         Constipation and nausea

·         Rash

Contact your healthcare provider if you experience severe flank pain that does not go away within a day or two. If you have any further symptoms, you should contact your doctor immediately. These signs may suggest the existence of a serious disease. You may lower your risk of acquiring illnesses that cause flank pain and discomfort by drinking enough water and maintaining a healthy weight.
