Pain under the left shoulder from the back, from the back, is an alarming signal from the body.What does it mean?

Pain that appears on the left under the shoulder blade is a fairly common symptom that can occur in men, women and even children.At first glance, such symptoms seem frivolous, but in fact, pain under the left shoulder blade from the back can be a harbinger of a number of dangerous diseases.

There are many reasons for the appearance of such a pain syndrome, and they are usually not at all related to problems in the shoulder blades themselves.Most often, the cause of pain is inflammatory and pathological processes in other organs and systems.

Why does it hurt under my left shoulder?

To understand why it hurts under the shoulder blade, we need to remember the anatomical structure of a person.After all, it is most often those organs that are located nearby that hurt, although it happens that the pain radiates along the nerve fibers away from the source of the disease.

The left shoulder blade is located on the ribs that form the chest.The ribs are connected to each other by intercostal ligaments and muscles, and between each rib there are intercostal vessels and intercostal nerves.In turn, the intercostal nerves arise from the spinal cord, which is located in the spinal cord in the center of the scapula.Along with the ribs, the scapula protects the left heart, left lung, stomach, spleen, pancreas and aorta.

Based on this location, the causes of pain can be divided into two main groups:

1. Pain associated with disorders of the musculoskeletal system, as well as muscle pain.
2. Pain associated with pathological changes in the functioning of internal organs (diseases of the gastrointestinal tract, cardiovascular system, spleen, respiratory organs).

The cause of pain in the scapula can be determined based on its nature, intensity and location:

• Pain radiating to left shoulder blade.The pathological source of such pain can be found far from the site of the pain.Most often, this symptom is characteristic of stomach or heart diseases.
• Aching pain under left shoulder blade.It indicates the presence of a prolonged chronic process.Such painful manifestations can be associated with chronic heart disease (pericarditis, myocarditis), as well as with cervical osteochondrosis of the spine.
• Dull pain under the left shoulder blade.It most often occurs against the background of the development of thoracic or cervical osteochondrosis.Typically, the pain spreads down from the back of the head along the back, arm, under the shoulder blade and is accompanied by nausea, dizziness, numbness (pins and needles) of the hands.
• Severe pain under the left shoulder blade.Intense pain is not typical for the scapula area, which means it serves as a signal of a pathological condition that can be life-threatening.At best, severe pain may indicate intercostal neuralgia, but more often such sensations indicate the presence of a peptic ulcer and the development of a pre-infarction condition.
• Severe pain under the left shoulder blade.Intercostal neuralgia can cause sharp pain - during inhalation, the pain syndrome is clearly intensified and there is a feeling that "it is taking your breath away".Sharp pain can be caused by left-sided pneumonia in the acute phase, while the patient feels cutting and stabbing symptoms throughout the left side of the chest, radiating to the left shoulder blade.Less often, severe pain can occur during the exacerbation of pancreatitis - the pain is of a girdle and cramping nature.

• Annoying pain under left shoulder blade.It can indicate the initial stage of development of cervical osteochondrosis.The pain starts just below the occipital bone and radiates to the left (or right) side of the back.
• Burning under the shoulder blade.This symptom may indicate prolonged intercostal neuralgia, angina attacks or myocardial infarction.Sometimes, the appearance of a burning sensation under the scapula may indicate the development of vegetative-vascular dystonia.In this case, the pain is accompanied by tachycardia, hand tremors and a strong feeling of fear.
• Constant pain under the shoulder blade on the left.Such a pain syndrome may indicate the development of left-sided pneumonia.In this case, the pain is accompanied by dry cough, low temperature, feeling of lack of air and shortness of breath.
• Stitching pain under left shoulder blade.Stitching pains (so-called "lumbago") are most often a sign of osteochondrosis, but can also indicate intercostal neuralgia.A tingling sensation in the back that appears during physical exertion, deep breathing or coughing can be a sign of the development of pleurisy or pneumonia.
• Oppressive pain.It indicates the development of osteochondrosis, and may also indicate the initial stage of coronary heart disease and the worsening of vegetative-vascular dystonia.
• Throbbing pain.Most often, the left protrusion of the intervertebral disc in the thoracic or cervical spine is manifested in this way.Throbbing pain may indicate a herniated disc or incipient aortic dissection.
• Severe pain under the left shoulder blade.Indicates dangerous conditions and requires immediate medical intervention.The causes of the pain syndrome can be: angina attacks, left protrusion of the intervertebral disc, gastric ulcer.

The nature of the pain and its location can vary, but most often the pain under the left shoulder is a very dangerous symptom that requires immediate medical intervention.

What diseases can cause pain under the left shoulder blade?

Painful syndrome on the left under the scapula is most often caused by pathologies of the musculoskeletal system, heart, stomach and bronchopulmonary system.

Let's consider the possible diseases associated with pain under the left shoulder blade and accompanying symptoms.

Diseases	The nature of the pain	Associated symptoms
Musculoskeletal system
Humeroscapular periarthritis	The pain appears in the shoulder area and radiates to the shoulder blade.	The patient cannot move freely (he cannot put his hands behind his head because of pain);there is a creaking in the joints when moving.
Intercostal neuralgia	The pain is localized in one of the spaces between the ribs and is accompanied by a feeling of numbness.The pain intensifies when you bend to the left.	Redness may appear along the inflamed area and characteristic rashes may appear on the skin.
Back muscle diseases (myositis, inflammation, lesions)	Back pain occurs suddenly and can be painful in nature.	The pain appears on the left side when the shoulder blade is injured or when the muscles are strained.
Oncology	Aching pain under the left shoulder blade or constant sharp pain.	With tumors of the scapula, the back part of the chest is deformed.
INJURY	Intense pain, especially the first few hours immediately after the injury.	If the pain intensifies with movement, swelling or swelling appears, this may be a fracture of the scapula or rib.
Osteochondrosis, spondylosis, thoracic scoliosis, intervertebral hernia	Severe pain manifests either on a continuous basis or in "lumbago".	Unpleasant sensations appear in the back - a feeling that "a pin has been inserted".
Heart diseases
Angina pectoris	Pain under the left shoulder blade from the back occurs during exertion and radiates to the left arm, left shoulder blade and sometimes to the left jaw.	Accompanied by shortness of breath and fear of death.
Myocardial infarction	Burning pain under the left shoulder blade on the side of the heart.	Heartaches cannot be eased with pills.The left arm goes numb, heavy shortness of breath appears and the sternum begins to "burn".
Pericarditis and myocarditis	Aching pain in the left side.	Accompanied by chills, more often appearing at night and increased temperature.
Dissecting aneurysm of the ascending aorta	The pain syndrome migrates from top to bottom.Initially, the pain appears in the chest, then gradually moves under the left shoulder blade and further to the lower back.	A sharp drop in pressure.
Diseases of the bronchopulmonary system
Left sided pneumonia	Moderately intense pain.	Cough with sputum, shortness of breath, fever.
Pleurisy	Pain appears during breathing	Shortness of breath, feeling of breath in the lungs.
Gastrointestinal pathologies
Stomach ulcer	Pain under the shoulder blade is accompanied by a burning sensation (usually at night).	Pain is associated with eating.
Perforated ulcer	Sharp, stabbing pain (like a stab).	Fever, vomiting.
Acute pancreatitis	The pain is radiating in nature and can sometimes radiate to the side.	Bloating, repeated vomiting, fever.

Other symptoms accompanying the pain syndrome can help identify the disease caused by the pain on the left side under the scapula:

• The pain worsens after eating– Peptic ulcer, pancreatitis, gastritis.
• The pain gets worse when you sneeze- bone diseases, injuries, pleurisy, neuralgia, joint and muscle pathology.
• The pain occurs when you turn your head– osteochondrosis, clavicle injuries.
• Pain appears during swallowing– diseases of the esophagus, psychosomatic disorders.
• Pain accompanied by shortness of breath– pleurisy, cardiac pathology, intercostal neuralgia.

• Pain causes coughing- damage to the respiratory system.
• Temperature display– infectious and inflammatory processes: pericarditis, purulent pleurisy, subphrenic abscess.
• Pain accompanied by numbness in the left arm– angina pectoris, osteochondrosis, myocardial infarction.
• Nausea and belching accompany the pain– gastrointestinal pathology (pancreatitis, ulcers, gastritis).
• The pain causes numbness in the tongue– angina pectoris, osteochondrosis, heart attack.

Pregnant women experience pain under the shoulder blade for the same reasons as other people, but the expectant mother has a much higher risk of developing certain diseases.The most likely cause of left back pain in a pregnant woman is osteochondrosis (due to the greater load on the spine), pyelonephritis (due to the displacement of the kidneys and activation of their activity) and excessive straining of the back muscles.

In children, pain under the shoulder blade usually occurs due to injuries, neuralgia (after hypothermia), myositis, pleurisy.

Diagnosis and treatment.Which doctor should I contact?

You should choose a doctor with whom to make an appointment depending on the nature of the pain and its manifestations:

• Emergency physician- with sharp, intense pain, burning in the chest, shortness of breath, when the pain is accompanied by severe dizziness, severe weakness or loss of consciousness.
• Neurologist- if the pain is accompanied by loads or movements.
• traumatology– if the pain appeared after an injury.
• Cardiologist– with a burning sensation behind the sternum, extending under the shoulder blade, in the left arm, in the jaw.
• Pulmonologist (or therapist)- if the pain intensifies during breathing and is accompanied by cough, shortness of breath and fever.
• Gastroenterologist- if the pain is accompanied by meals and accompanied by dyspeptic disorders.
• Surgeon- pain under the shoulder blade is associated with deformation of the sternum, with sharp pains associated with high temperature.

If it is difficult to decide on the choice of a doctor yourself, you should contact a therapist who, based on the results of the examination, will schedule an appointment with a specialist.

Diagnostic measures are prescribed depending on the reasons that caused the pain under the left shoulder blade, behind:

• General examination - taking an anamnesis and interviewing the patient, visual examination (measurement of pulse, blood pressure, temperature, palpation, auscultation), taking blood and urine tests.
• X-ray, CT and MRI examination - determines spine pathologies and diseases of the musculoskeletal system, as well as diseases of the pulmonary system.
• Abdominal ultrasound, FGDS – gastrointestinal disease.
• Ultrasound and ECG - prescribed for the examination of cardiovascular diseases.

The treatment regimen for pain under the left shoulder is selected specifically for each disease - there is no single treatment protocol.

Important!The treatment of pain under the left shoulder blade is mainly the treatment of the disease that causes the pain syndrome.

If the pain is associated with cardiovascular pathology, cardiological medications and a gentle diet to physical and psycho-emotional activity are prescribed.

Gastrointestinal pathologies that cause pain are treated by taking antacids and prescribing a bland diet.

Diseases of the musculoskeletal system are treated with long-term therapy, including taking anti-inflammatory drugs and performing special therapeutic exercises.

Surgical treatment is prescribed when conservative therapy is ineffective.Surgery is mandatory for perforated ulcers, severe gastrointestinal pathologies, rupture of the spleen and intervertebral hernia.

If you have pain under the left shoulder blade, you should definitely undergo an examination by a doctor to avoid the appearance and development of life-threatening pathologies.
