Why does kidney pain occur?

Such a symptom as pain in the kidneys or the lumbar region should always be alarming, because it may indicate the occurrence of serious diseases from both the kidneys and other organs: the liver, pancreas, adrenal glands and even the appendix.

Therefore, if there is pain in the right or left kidney, it is necessary, first of all, to figure out what caused the condition, and then proceed to the appropriate treatment.

Why kidneys hurt: causes

Pain in the area of ​​the kidneys is most often associated with lesions of the kidneys themselves, or are caused by inflammatory processes caused by infections. There are cases when back pain is mistakenly interpreted as renal colic.

It is worth remembering that the real pains in pathological conditions of the kidneys rarely manifest themselves, but are complemented by other symptoms, in particular pain, fever, changes in urination, general poor health.

Consider the most common causes that cause pain in the kidney area:

  • urolithiasis disease;
  • pyelonephritis;
  • cyst of the right or left kidney;
  • hydronephrosis;
  • nephroptosis;
  • hypothermia;
  • renal failure;
  • glomerulonephritis;
  • deviations in the health of the body during pregnancy.

The question "why the kidneys hurt" can not give a clear explanation to any expert. It is known that pain in the kidney area is always a symptom of a disorder or disease. In some cases, pain in the kidneys can occur as a result of intense physical exertion and after lifting weights.


This is an acute or chronic disease characterized by inflammation of the structural element of the kidney - the nephron, or rather the renal glomeruli. Pain in the kidneys is more characteristic during the period of acute glomerulonephritis or acute or severe exacerbation of chronic.

In addition to the presence of pain in the kidneys, the disease is accompanied by the presence of protein in the urine, edema, and high blood pressure (arterial hypertension).


Pyelonephritis is an infectious pathology that affects the kidneys, renal calyx and pelvis. Infection can be caused by various pathogens. Almost always it has a bacterial character.

Dull aching pain in the kidney area is characteristic of pyelonephritis. Depending on the side of the lesion, there may be pain in the right, in the left kidney, or bilateral pain. Most often, renal pain with pyelonephritis is permanent. It is not very strong, but, nevertheless, it gives the patient a certain anxiety.


The disease in its early stages can cause almost no discomfort to the patient. Patients note that from time to time unsharp, pulling pains in the lumbar region recur.

Then, as the disease progresses, the blood supply to the kidneys deteriorates, the urine begins to stagnate, and it is possible to detect an elevated amount of protein and red blood cells. In the third stage of the disease, patients begin to complain that they constantly have kidney pain. Such pains in the kidney often lead to depression, neurasthenia in a patient.

Kidney disease

It refers to the common causes of kidney pain. At the same time, the pain syndrome is very intense, it develops after a shaky ride, playing sports - then the stone begins to move along the ureter, touching its nerve endings.

In this disease, the pain in the lumbar region is very strong, it does not allow to find the position of the body in order to alleviate it, accompanied by urge to urinate. The volume of urine is very small, often with mixed blood.

Renal failure

It develops on the background of violations of the full work of the kidneys. This disease is accompanied by increased blood pressure, swelling of the lower limbs and face, pain in the lumbar region, sometimes so severe that a person may lose consciousness.

Kidney cancer

Symptoms of cancer are very difficult to detect, because in the early stages of the disease proceeds without any signs. Already in the later stages, the patient develops blood in the urine and a very strong pain in the kidneys, which indicates that the process of tissue destruction has begun.

How the kidneys hurt: symptoms

It is very difficult to diagnose precisely that the kidneys hurt only with the help of human sensations, since the liver, intestines, spinal column, urethral system and spleen are located in the immediate vicinity of the kidneys, therefore, in any case, comprehensive diagnostics and specialist consultation will be needed.

Let us consider in more detail certain symptoms in order to understand what pains bother a person when kidneys are sore:

  • pain in the kidneys and lumbar region;
  • a marked decrease in the daily amount of urine;
  • turbidity of urine, the presence of blood, small stones, sand in it;
  • frequent urination to expel a small amount of urine;
  • burning sensation when urinating;
  • blurred vision, pruritus.

The main sensation arises from the back under the lower ribs and above the pelvis. This condition is accompanied by an unpleasant pain syndrome piercing, pulling, cutting or acute paroxysmal character. Localization of pain does not matter much. As a rule, the symptoms of pain in the right kidney are no different from the symptoms characteristic of the left.

Treatment of pain in the kidney area

If there is pain in the kidneys, the treatment is carried out after a full range of examinations to identify the cause of the disease. To do this, the patient is assigned an ultrasound, computed tomography of the kidneys, taking the necessary tests.

Only after a series of diagnostic measures is established an accurate diagnosis. Having determined the correct treatment regimen, the urologist will prescribe the necessary medicines.

Kidney pain caused by pyelonephritis or glomerulonephritis treated with antibiotics. If kidney pain is caused by the presence of stones, then treatment is aimed at relieving pain, removing stone and fighting infection.

Surgical treatment, including urgent, is carried out with such diseases:

  • kidney injury (rupture, crush).
  • benign adenoma, fibroma.
  • malignant tumors.
  • renal artery thrombosis (thromboembolism).
  • urolithiasis in the stage of exacerbation and blockage of the urinary duct.
  • purulent pyelonephritis in the acute stage.
  • purulent extensive abscess of the right kidney.
  • kidney cyst, purulent, large.

To self-medicate with the help of popular recipes, many of which are very doubtful, can be fraught with a sad outcome. Kidney disease is not a reason for independent experiments.
