Very often, pain under the left shoulder blade from behind from the back can disturb. It occurs after a sharp and strong movement or a long stay in an unsuccessful position. But it can also be a symptom of a serious illness that requires mandatory treatment. The causes of pain can be divided into two main groups: pain caused by diseases of the musculoskeletal system and pain associated with disorders in the internal organs.
Diseases of the musculoskeletal system
Various diseases of the spine can cause pain in the shoulder blade. In addition, pain may be a secondary symptom of injury. The reasons why it hurts under the left shoulder blade from the back can be different.
Osteocondritis of the spine
Osteochondrosis appears due to changes in the spine, when bone tissue is destroyed under the influence of various factors. And there are a lot of factors leading to this pathology:
- Curvature of the spine as a result of poor posture. Often found in students, schoolchildren and office workers.
- Statistical and dynamic overload of the body in immoderate volumes.
- Overweight and malnutrition.
- Back injury.
- Weak immunity and hereditary factor.
- Flat feet.
- Colds and frequent hypothermia, chronic intoxication.
- Metabolic disease.
- Prolonged exposure to vibration.
- Stress and sedentary lifestyle.
With cervicothoracic osteochondrosis, severe pain appears in the neck, back, shoulders and upper limbs, it can pull under the shoulder blade. There are pain sensations in the teeth, muscles, abdomen, heart area. The sensation begins to disturb when it pricks under the shoulder blade, numbness in the cervical and chest region, as well as in the neck and abdomen. Sleep is disturbed, the sensitivity of the hands, blood pressure indicators begin to fluctuate, and performance decreases. It can also bake behind the sternum.
This disease occurs when irritation, inflammation, pinching of the intercostal nerves or their compression. This occurs with inflammation, infections, chemical poisoning, allergies and hypothermia. The main symptom of neuralgia is pain, concentrated in the region of the heart. It can be dull or sharp, stabbing, aching or burning. May be episodic or permanent.
There may also be increased sweating, discoloration of the skin, tingling, or loss of sensation in certain areas. With a forced fixed position, the pain syndrome may recede.
Traumatic lesion of the scapula
If the left shoulder blade hurts, the causes may be caused by injuries. They can appear from a direct blow to the shoulder blades or after a fall on the back or shoulder. In the first hours after the injury, a very strong pain syndrome appears. It is a symptom of a fracture of the scapula or ribs. In the future, swelling and edema develop. With a fracture of the ribs, it is difficult for a person to breathe, and damage to the bone is noticeable on palpation.
This disease is an abnormal congenital location of the scapula. The cause of this pathology is not yet known to science. There is an opinion that the disease develops under the influence of external and internal negative factors on the fetus, at 3-4 weeks of pregnancy. At this time, the shoulder girdle and spine are formed. Often this disease is combined with other pathologies: fusion of the ribs, clubfoot, the formation of additional hemivertebrae, and an abnormal structure of the cervical region are noted.
Pathology is detected immediately after the birth of the child. With a mild degree of development of the disease, the following are prescribed: exercise therapy, massage, water procedures, physiotherapy. In moderate and severe cases, surgical treatment is prescribed.
Under the influence of various factors, the work of the muscular apparatus and the membranes covering the muscles is disrupted. There are small painful seals in the muscles, the so-called trigger points. They appear under the influence of trauma and muscle strain. There are several factors leading to their formation: forced posture, diseases of the spine, bruises, monotonous movements, somatic diseases, emotional overstrain.
The main symptom is pain, which has a aching, pulling character, which increases with exertion and activation of triggers. The sensitivity of the skin also increases, the color of the skin changes, and movement in the affected area is limited. Complex treatment is prescribed. For prevention, you should monitor your weight, adhere to a healthy lifestyle, wear comfortable shoes and clothes, avoid stress and hypothermia.
Changes in the work of internal organs
If there is pain in the left shoulder blade from behind, the reasons may be in violation of the internal organs. In many diseases, the symptom is pain in the left side. They are divided into cardiological, diseases of the bronchopulmonary system and the gastrointestinal tract.
With cardiac diseases, it hurts not only in the region of the left shoulder blade, but also in the region of the collarbone, in the left arm, in the abdomen. Myocardial infarction is one of the varieties of coronary heart disease, in which necrosis of the heart muscle occurs as a result of a violation of the coronary circulation. There is a burning, squeezing or pressing pain behind the sternum, radiating to the left collarbone, shoulder blade, arm and jaw. The patient appears cold sweat, there is a feeling of fear. These symptoms are a direct indication for emergency hospitalization in a medical facility. If timely medical care is not provided, then a fatal outcome is possible.
The cause of coronary heart disease is insufficient blood supply to the heart muscle due to coronary vascular disease. Heart arteries clog with cholesterol plaques or narrow. The heart does not receive enough blood to function normally. The reasons are:
- Atherosclerosis of the coronary vessels.
- arterial hypertension.
- Violation of lipid and lipoprotein metabolism.
- High cholesterol and being overweight.
Symptoms are shortness of breath, weakness, arrhythmia, increased sweating. There are spontaneous chest pains that are not affected by nitroglycerin. The patient experiences a lack of oxygen, there is a fear of death, apathy, a dreary mood or unreasonable anxiety. With an attack of angina pectoris, the pain is concentrated behind the sternum. It has a cutting, pressing, compressive and burning character of manifestation. The attack lasts from 2 to 5 minutes and is effectively stopped by drugs.
With pericarditis, an inflammatory process appears in the outer shell of the heart. The causes of inflammation are infections, autoimmune diseases, injuries, tumors, metabolic disorders. There is pressing pain in the chest, swelling of the face and neck, severe shortness of breath, dry cough and hoarse voice.
Mitral valve prolapse is a pathology in which the function of the valve located between the ventricle and the atrium is impaired. It is detected by chance and does not pose a danger to the patient's life. May be congenital or acquired. Another disease that is usually asymptomatic is an aortic aneurysm. With this pathology, a protrusion of the vessel wall occurs due to its weakening or a strong increase in blood pressure. The wall of the vessel is weakened by the deposition of foreign substances, inflammation or tissue destruction.
Pathologies of the bronchopulmonary system
In diseases of the bronchopulmonary system, pain appears in the scapula on the left.
The reasons for which a pain symptom appears: acute bronchitis and tracheobronchitis, left-sided pneumonia, dry left-sided pleurisy, abscess of the left lung. Acute bronchitis is manifested by cough, weakness, increased sweating, shortness of breath and decreased activity, fever up to 38 degrees. The causes of the development of pathology are of viral or bacterial origin. Physical, chemical and allergic factors also influence.
Left-sided pneumonia is rare, but it poses a threat to the life of the patient. The main reason is the penetration of pathogens into the left lung. This occurs with a strong decrease in immunity. There is a strong debilitating cough, burning and pain on the left side of the chest, body temperature rises. It is necessary to seek help as soon as possible, this will help to avoid the development of complications. A disease such as dry pleurisy can be a complication of other lung pathologies. A lung abscess is a complication. It is formed as a result of undertreated pneumonia.
Diseases of the gastrointestinal tract
A very common group of diseases in which pain radiates to the left shoulder blade from behind. The reasons may be different. The growth of pathologies is associated with errors in nutrition, the use of food containing flavorings and preservatives. The symptoms of these diseases are:
- Abdominal pain.
- Nausea and vomiting.
- Smell from the mouth.
- Decreased body weight and appetite.
With a stomach ulcer, the integrity of the tissues of the walls of the stomach is violated, as a result, they are corroded by gastric juice and an ulcer appears. A feature is the hungry pains that appear against the background of hunger. After eating, they subside. Another symptom is vomiting with sour contents. Also, the motility of the stomach is disturbed, as a result of which belching and heartburn appear. A complication of the disease can be bleeding, due to the defeat of the ulcer of the blood vessels. This is a very serious disease in which self-medication is dangerous, as it can lead to perforation of the ulcer and death.
The main symptom of a duodenal ulcer is pain in the epigastric region, which can radiate to the left side of the chest and scapula, lumbar or thoracic spine.
Pain occurs after eating, and also after a while. It is stopped by antacids, antispasmodics and antisecretory agents. Also, ulcers are characterized by dyspeptic disorders, lack of appetite, which leads to weight loss and painful weight loss. An ulcer causes complications: bleeding, perforation and penetration into the pancreas, duodenal stenosis, tumor formation at the site of ulcer formation, and inflammation of the intestinal lining.
Spasm of the esophagus is characterized by a violation of swallowing.
The cause can be excitement, as well as rapid absorption and poor chewing of food, consumption of foods high in fiber. You can relieve discomfort by drinking a large amount of liquid, swallowing air and doing exercises. Also a symptom is the reverse reflux of the contents of the esophagus. Often occurs in a dream or when the patient takes a horizontal position. It manifests itself in the form of vomiting without admixture of gastric juice and bile.
When the contents of the stomach and duodenum are thrown, gastroesophageal reflux disease develops.
The main cause is weakness of the lower esophageal sphincter. In this case, when the stomach contracts, its contents are thrown back into the esophagus. It is characterized by heartburn, which appears when bending over, exercising, after a heavy meal. There is an eructation with a bitter or sour taste. You may also experience nausea and vomiting.
Signs of acute pancreatitis are severe, constant, sharp pain felt under the ribs.
There are two causes: alcohol abuse and cholelithiasis. Symptoms are not always pronounced. The pain is poorly relieved by painkillers, sometimes it is necessary to prescribe narcotic drugs. Also, pain under the shoulder blade can be disturbing with intestinal colitis. Appears due to infections, medications, chemical or food poisoning, circulatory disorders.
