Back pain in left side - causes, symptoms and what to do

Probably, there is not a single person over 40 who has not felt lumbar pain of different degree of localization, including pain in the lower back in the left side, at least once. And some experienced this dubious pleasure at a much younger age. In this case, many in the hope that the pain will cease, they start to drink handfuls of painkillers, rub themselves with "grandmother" tinctures. And it really helps. Sometimes.


After all, in order to eliminate the lumbar pain, you must first establish its cause. Pain itself is a nonspecific symptom and worries the patient for almost all diseases. A pain on the left side of the lower back is noted with the following diseases and pathological conditions:

  • Diseases and injuries of the spine - lumbosacral radiculitis, osteochondrosis, disc hernias.
  • kidney disease - urolithiasis
  • atypical course angina and myocardial infarction
  • diseases of the stomach, intestines, gallbladder, pancreas
  • pneumonia with pleural involvement
  • diaphragmatic hernia
  • sinistral inflammation of the uterine appendages
  • gestation
  • tumor process


This impliesthat pains in a waist at the left are found practically at all diseases with involvement of the locomotor system and systems of internal organs. Most often, the appearance of pain on the left lower lumbar leads the pathology of the lumbar spine - osteochondrosis, trauma, curvature of the spinal column. With all these states, an asymmetric displacement of the intervertebral disc occurs with subsequent infringement of the roots of the spinal nerves from one side, in this case to the left. As a result, there is a sharp pain in the type of lumbago, which increases when moving and changing the position of the body.

During an attack of renal colic in urolithiasis, the pains appear abruptly, cramped and accompanied by nausea and vomiting. They arise because of obstruction of the renal pelvis and ureter with subsequent violation of the outflow of urine. In the inter-attack period, the character of the pain syndrome changes. Sometimes the kidney increases in size and the renal capsule stretches. In such cases, the patient is concerned about the pulling pain that radiates( radiates) to the left hip and to the groin.

With stenocardia and myocardial infarction, classical pain syndrome behind the sternum is not always marked by the type of tie. If the posterodiaphragmatic parts of the myocardium are affected, the process can occur atypically and the patient notes pain in the left side of the waist. The pain is intense, accompanied by fear of death and does not depend on the position of the body.

In acute and chronic diseases of the digestive system, there is a pain in the waist and abdomen on the left. During turbulent processes requiring surgical intervention, this pain is intense and is accompanied by local tension of the muscles of the waist and abdominal wall. With chronic diseases of the stomach, intestines, gall bladder, there are aching pains associated with eating. On the example of the gallbladder and liver, which are located on the right, you can see that not always the localization of pain coincides with the anatomical location of the diseased organ. Doctors explain this by the projection zones of Zakharyin-Ged, which are located in different parts of the skin of the back.

With pneumonia, the pleura may be involved in the inflammatory process. The inflamed left pleura irritates the nerve endings of the diaphragm, resulting in a left-sided lumbar pain. Although it is fair to say that with pneumonia, the right lung is more often affected. In addition to the patient's pain, cough, shortness of breath, and fever are disturbed. With left sided inflammation of the uterus with appendages, the patient also complains of lumbar pain on the left.

When pregnant in the body, the woman changes the anatomical location of the organs and their function. Pregnant uterus presses on the intestinal loops, bladder, spleen. The intra-abdominal pressure increases, the diaphragm shifts upward, the nerve fibers of the lumbar and sacral plexus become irritated. Lumbar pain can be one-sided, left or right. By nature, it is often mild. With a sharp increase in pain in conjunction with the expiration of blood from the vagina, a woman should immediately call an ambulance.

Diagnostic Studies

For the diagnosis in each specific case, a whole complex of laboratory and diagnostic studies should be carried out. What will be included in these studies will be determined by the attending physician. As a rule, this is a therapist or neurologist. But, if necessary, other specialists are connected - radiologist, surgeon, traumatologist, gynecologist, ultrasound doctor.

Even an ordinary general laboratory blood test can tell a lot. On the basis of some signs( an increase in the level of leukocytes, the rate of erythrocyte sedimentation), one can be suspected of having an inflammatory process in the body. To confirm or exclude this process in the kidneys, a laboratory urine test is performed. For a more accurate diagnosis, a radiograph of the lungs, lumbar spine is performed, an electrocardiogram is recorded. If necessary, resort to high-precision methods - computed tomography, ultrasound, magnetic resonance therapy.
