Basically, pain under the scapula on the left side of the back is more often characteristic of people from older age groups, but often similar diseases appear at a younger age.pain under the scapula in a manPoor posture, hereditary factors, or sports injuries may be the cause of this condition. The main cause of pain under the left shoulder blade from behind from behind should be considered in more detail. However, this discomfort can be considered a good reason for a visit to a specialist.

Causes and types of pain under the left shoulder blade in the posterior part of the back

The reasons for the development of these pathologies are different, they have their own characteristics. Pain on the left side below the scapula in the posterior part of the back is characterized by the following sensations:

  • sharp;
  • stupid;
  • attract;
  • sewing;
  • shoot.

Pain under the left shoulder blade from behind can be of the same type, or alternating. Sometimes one type of discomfort is replaced by another, for example, the stabbing turns into a shooting. Pathology is caused by various injuries and, as a consequence, disorders of the musculoskeletal system:

  • rib damage - discomfort felt throughout the shoulder;
  • osteoporosis, arthritis - affects, in addition to the scapula, neck and shoulders;
  • disc displacement - pain provokes stenosis of the spinal canal;
  • wear (aging) of the skeletal system - unpleasant sensations in the scapular area can occur when bone structure changes in old age;
  • bursitis - the formation of exudates during inflammation of the periarticular bag also causes pain;
  • rupture of the rotator cuff - sharp and sharp pain in the area of the left scapula from behind from behind with inability to rotate the arm reported violation of the shoulder muscles or tendons responsible for the coordination of the shoulder joint;
  • dislocation - discomfort in the left side of the back may be due to dislocation of the clavicle or shoulder joint;
  • nerve damage - pinching of the dorsal scapular nerve is also characterized by a painful sensation in the back (below the left scapula).

Back pain radiating in the shoulder blade area on the left is considered a signal indicating the following pathology:

  • purulent pneumonia;
  • acute inflammation of the bronchial mucosa;
  • focal pneumonia;
  • lung pleurisy;
  • gastric ulcer;
  • esophageal spasm;
  • pancreatitis;
  • gastroreflux.

Heart disease can be another reason that a patient has back pain on the left side below the scapula:

  • heart attack;
  • pericarditis;
  • angina pectoris;
  • mitral valve prolapse.

In addition, it causes discomfort and pain under the left shoulder blade from behind - an increase in muscle tone:

  • poor posture;
  • uncomfortable position during sleep;
  • cervical muscle stretching.

Only a visit to a specialist can accurately determine the cause of the burning sensation under the left shoulder blade from behind from behind.

Diseases of the broncho-pulmonary system

Pain in the left shoulder blade in the posterior part of the back may occur if there is a problem with the lower respiratory tract (bronchi, lungs, pleura). The main causes of respiratory pathology are considered to be diseases caused by viruses and pathogenic bacteria:

  • bronchitis;
  • pneumonia;
  • pleurisy.

Neoplasms of the lungs or bronchi are also capable of causing a burning sensation under the left shoulder blade from behind from behind.

Lung pleasure

Increased pain below the left scapula in the back when coughing, breathing or sneezing is characteristic of dry pleurisy. This process takes place with an increase in temperature (up to 38 ° C), a feeling of general weakness, sweating, headache, as well as pain in muscles and joints.


If the back hurts on the left side below the scapula for a long time, then this may be a sign of pneumonia. The symptoms are similar to pleurisy and are often accompanied by the following symptoms:

  • bloody clots on saliva;
  • wet cough (less frequent dryness);
  • lack of oxygen;
  • increase in body temperature (37. 5 ° C - 37. 9 ° C).

Gastrointestinal tract

One of the most common causes of scapular back pain is diseases of the digestive system, especially peptic ulcer and pancreatitis.


Back pain below the left shoulder blade, which is based on pancreatitis, is not uncommon. They usually occur in parallel with lower back pain and cramping contractions. They arise unexpectedly in the heart, chest, or back area.

Peptic ulcer

With the development of peptic ulcer, a person experiences abdominal pain or heartburn. A large number of patients (approximately 75%) felt relief from vomiting, which was caused by significant pain with previous nausea. Initially, discomfort is observed in the epistragal area, and then the pain can spread to the left side (nipple, sternum, back). Often, an increase in pain occurs after eating.

Cardiovascular system

Pain under the left shoulder blade from behind from behind is not considered a characteristic sign of a particular disease, but damage to the cardiovascular system is considered one of the important factors. Major diseases with these characteristics include: angina pectoris, myocardial infarction, aortic aneurysms, hypertensive crisis and pericarditis.

Angina pectoris

With angina pectoris, a person experiences acute left side subcapularis pain from behind, for removal of which nitroglycerin is used. Angina pectoris attacks can be caused by physical activity, psychophysical factors, hypothermia, overeating and consuming large amounts of alcohol.

Myocardial infarction

The characteristic pain below the scapula on the left side of the back from the back can be caused by the complete absence of coronary blood supply to one of the myocardial sites due to duct obstruction. The causes of heart attacks are:

  • atherosclerosis;
  • thrombosis.

When a thrombus (plaque) is torn, it enters the heart with blood flow and, once in a small -diameter coronary artery, they block the ducts and interfere with the delivery of blood to the tissues. With a lack of oxygen, the process of death of myocardial cells begins.

Symptoms of myocardial infarction include acute and throbbing pain, concentrated in the left side of the sternum. Distributed in:

  • Left hand;
  • shoulder blade;
  • Lower jaw.

It is impossible to stop pain during a heart attack with the help of analgesics, and nitroglycerin can only reduce pain.

Aortic aneurysm

In half of the cases of thoracic aortic aneurysms in the early stages, there are no signs of the disease. Symptoms depend on the location of the aneurysm, its size and the presence (absence) of surgery. In addition to pain in the scapula from the back, the following complaints are possible:

  • discomfort in the left back, neck, lower jaw;
  • chest ache;
  • cough, hoarseness, shortness of breath.

May be accompanied by signs of heart failure due to heart failure. Symptoms can arise suddenly and are expressed by severe pain in the left chest and back.

Hypertensive crisis

Contrary to popular belief, hypertensive crises are not characterized by standard blood pressure numbers, they are purely individual. In addition to signs that the patient has colitis below the left scapula from the back of the back, symptoms of a hypertensive crisis should include:

  • headache in the back of the head;
  • pulses in the temples;
  • difficulty breathing;
  • dizziness and vomiting;
  • sight problem;
  • redness of the skin;
  • increased diastolic blood pressure values above 110-120 mm Hg. Art.

When a hypertensive crisis occurs, the risk of complications of a number of systems and organs, the central nervous system, etc. increases.


Patients may show symptoms of inflammation (acute pericarditis) or signs of fluid accumulation (pleural effusion). They vary depending on the stage of the inflammatory process and the volume of pericardial fluid. With acute pericarditis, pain occurs on the left side below the scapula in the back, in the chest, and sometimes shortness of breath is observed. And even the first manifestations may be coordinated with the development of hypotension, shock or pulmonary edema.

Musculoskeletal system

Various destructive pathologies in the spine, bones, can cause back pain under the left shoulder blade. In addition, they include: intercostal neuralgia, osteochondrosis and intervertebral hernia.

Intercostal neuralgia

Pain in the back in the left shoulder blade with neuralgia has its own characteristics, for example, intensification during physical exercise, and the point of pain can be determined by palpation. Pain with neuralgia is long -lasting and is not minimized with nitroglycerin.


Osteochondrosis is often the cause of pain under the scapula on the left side of the back and is characterized by the following symptoms:

  • muscle spasms, numbness;
  • development of dizziness;
  • the appearance of "goose bumps" (paresthesia);
  • frequent headaches.

Intervertebral hernia

A hernia occurs when the annulus fibrosus that surrounds the intervertebral disc rupture, resulting in displacement of the disc core. The symptoms of a herniated disc depend on its location. The most important symptom of a herniated disc is pain in the left side of the back, which multiplies with movement or lifting of a load.

Psychosomatic illness

One of the causes of pain under the left shoulder blade from behind from behind can be considered a psychosomatic illness. Not all specialists are able to identify the disease and its true cause, as they often do not have special features. Different organ systems can have a direct relationship with the dynamics of the patient's mental state:

  • Gastrointestinal tract;
  • cardiovascular system;
  • nervous system;
  • immunity.

Treatment of pain under the left shoulder blade from the back from the back in psychosomatic diseases occurs without the use of traditional therapies. In such cases, it is important to establish psychological motives and carry out treatment with a psychotherapeutic bias.
