Flank pain is a fairly common symptom observed in medicine. Depending on the precise point of localization of pain, certain organs may be affected, and the specialist may suspect a pathology.
What are the possible causes of flank pain, depending on whether the pain is located in the left or right flank? This article will address all the questions you have about this symptom by trying to provide some clarification. He will also discuss what to do in the presence of flank pain.
The abdomen is classically divided into 9 parts: the hypochondria right and left, theepigastrium, flanks right and left (or lumbar regions), The periumbilical region, iliac fossa right and left and the suprapubic region or hypogastrium.
A pain in the flank is therefore a pain located in the middle of the belly, to the right or to the left of the navel. The other parts of the abdomen are:
- The hypochondrium (right and left) that lie immediately below the ribs
- THEepigastrium is between the sternum and the navel
- La periumbilical region is the part in the middle of the right flank and the left flank around the navel
- The iliac fossa (right and left) are located in the lower abdomen on either side of the pubis
- THEhypogastrium is located between the pubis and the navel in the middle of the 2 iliac fossae.
Possible causes of flank pain
Left flank pain
Pain in the left flank is often related to the organs located there. These are the pancreas, intestines, part of the stomach, spleen, kidneys, ovaries.
Stomach : if this organ is affected by a pathology, the patient may feel pain in his left flank. It can be a less serious problem like a gastric ulcer (1) or gastritis (2). These pains can also evoke more serious pathologies such as stomach cancer (3) or a hiatal hernia
The intestines : when the intestines are affected, pain in the left flank can highlight the following diseases: an obstruction or bowel obstruction (5) diverticulosis or an diverticulitis (6) Crohn's disease (7) colon cancer (8), etc It could just as well be intestinal gas or Constipation
The pancreas : The acute pancreatitis (10) is the main pathology to be feared in case of left flank pain related to the pancreas. In this case, other signs are associated such as vomiting, palpitations and fever.
The spleen : Normally the spleen is not palpated in the left flank. But in a pathological state where its volume is increased (splenomegaly ), it is found in the left flank and its palpation can be painful.
The ovaries : A woman who suffers from ovarian cysts (12) will feel pain in the left flank when the left ovary is affected.
Kidneys : the presence of kidney stones (13) causes severe pain in the left flank radiating into the back. This type of pain is called renal colic. It is also common to see patients presenting with hydronephrosis (14) kidney cancer (15) or any other kidney problem that manifests as pain in the left lumbar region.
Right flank pain
Right flank pain generally affects the organs located in this region such as: the colon (large intestine), the gallbladder and the bile ducts, the kidney, the pancreas. The most common cause of right flank pain is cholelithiasis
Cholelithiasis is the presence of stones in the bile ducts slowing down or blocking the passage of bile. The bile is a physiological liquid which consists in facilitating the digestion of certain foods by the liver. It is stored in the gall bladder before flowing into the intestines to be excreted. It can happen that the cholesterol contained in the bile forms small crystals called gallstones or cholelithiasis.
The inflammation of the wall of the gallbladder by these stones, more or less associated with an infection of the bile, leads to another painful picture called acute lithiasic cholecystitis (17). The flank can then be very painful accompanied by other signs such as: nausea, vomiting, abdominal defense.
Pain in the right flank can also suggest a kidney stone, an infection of the kidney and ureter called pyelonephritis
It is also possible that pain at this level is due to a intestinal hernia (19), a Constipation or an bowel obstruction as the case on the left. Similarly, in women we can think of ovarian cysts, to one ectopic pregnancy (20) or a ovarian cancer
Finally, pain in the right flank can be a mild form ofappendicitis (22). A careful examination by the doctor as well as additional assessments will confirm the diagnosis.
Some pain felt in the left or right side of the stomach can come from other parts of the body such as the dorsal spine. We are therefore talking about referred pain due to nerve root irritation (radiculopathy) coming out on either side of the dorsal spine, thus innervating regions near the flanks. Several causes are at the origin, in particular the rheumatological pathologies (23) and minor intervertebral disorders
To learn more about referred pain (also called referred pain), see the following article.
Parietal and muscle pain
They can also cause flank pain. For instance :
- a conflict of the anterior branch of the abdominal cutaneous nerve (25)
- Myofascial syndromes (26) concerning contractures of the psoas muscles and transverse and oblique abs. These contractures can come from a bad posture, from a disorder of the spinal statics or be due to the practice of sport.
What to do in the face of flank pain?
In front of a patient who complains of pain in the flank, the health professional will have to do a good interrogation. Sometimes the answers given by the patient are not precise enough to guide the specialist in the right direction.
He will continue with a clinical examination to look for other associated physical signs. Depending on this examination, the doctor will request additional assessments to better guide his diagnosis.
There are several possible analyzes depending on the pathology suspected by the doctor. Indeed, he may request an X-ray of theabdomen without preparation for exploration of the colon. This will allow him to confirm a Constipation or an bowel obstruction.
THEscan as for it, it is the examination of first choice when the doctor wants to look for a pathology affecting the following organs: ovaries, pancreas, spleen, kidneys, gallbladder.
If the pain is accompanied by fever and other digestive symptoms, a biological assessment may be requested in order to analyze the blood, stools, urine, etc. For example, thecytobacterioligical urine exam is done to look for a urinary tract infection.
If the doctor suspects the presence of stones or tumors, he may order a abdominal scan. A Magnetic resonance imaging (IRM) may be requested in case the doctor wishes to explore the abdominal cavity in more detail.
The treatment of flank pain goes through the treatment of the pathology in question. The pain may be relieved by antispasmodics and laxatives if it is pain related to digestive transit (constipation and others). In the case of renal colic, it will be managed by nonsteroidal anti-inflammatory drugs.
If the cause of the pain is muscular, the goal will be to relax the tense musculature in order to relieve the symptoms. Modalities such as massage may be relevant. It is even possible to relax the trunk muscles independently using tools such as a massage gun (like this one), A massage roller or an heated lumbar belt.
In extreme cases, the treatment can also go through a surgical intervention for many pathologies (kidney stone, cholelithiasis, intestinal obstruction, appendicitis, tumors, etc.). We must never forget the importance of rest in the management of flank pain.
