Shoulder blade pain is a common ailment that can sometimes be difficult to diagnose. Most of the time, the discomfort is due to something relatively harmless, such as muscle tension or poor posture. Occasionally, however, pain in or between the shoulder blades can also indicate more serious conditions. Therefore, persistent or severe pain should never be ignored.
The shoulder blades, medically known as scapulae, are two triangular bones attached to the collarbones and upper arms. They form part of the upper back and work together with muscles, ligaments, joints, nerves, and the thoracic spine to support movement and stability.
Because this region is so complex and also protects vital organs such as the heart and lungs, it can sometimes be difficult to determine the exact cause of the pain.
Common symptoms of shoulder blade pain
Pain in the shoulder blade area can occur on one or both sides of the upper back. The sensations can vary greatly and may include the following:
• Dull, pulling pain
• Sharp or boring pain
• Burning sensation
• Pain between the shoulder blades
• Pain that worsens with movement
• Tenderness in the shoulder blade area
Sometimes the pain originates directly from the shoulder blade area. In other cases, it is referred pain, meaning the source of the pain lies elsewhere in the body.
muscle strain
One of the most common causes of shoulder blade pain is muscle tension. Repetitive activities, lifting, sports, poor posture, or even sleeping in an awkward position can put excessive strain on the muscles around the shoulder blade.
People who perform monotonous tasks for long periods often develop chronic pain in their upper back and shoulders. Even starting a new exercise program can put additional strain on these muscles.
Improved posture, regular breaks, stretching exercises and sufficient recovery time can often alleviate muscle-related shoulder blade pain.
Disc problems
Degenerative disc diseases and herniated discs can also contribute to discomfort in the shoulder blade area.
With increasing age, the intervertebral discs gradually lose fluid and flexibility. A herniated disc occurs when the soft core of a disc pushes outwards and irritates adjacent nerves. If nerves in the neck area become pinched or inflamed, pain can radiate as far as the shoulder blades.
Fractures
Although scapular fractures are relatively rare, they can occur after severe trauma such as traffic accidents or falls. These injuries require immediate medical attention, as they are often accompanied by other serious injuries.
However, muscle tension and spinal problems are only part of the story – some surprising illnesses in other parts of the body can also trigger pain in the shoulder blades.
arthritis
Osteoarthritis is a degenerative joint disease that can affect the joints around the shoulder blade. It can cause pain, swelling, stiffness, limited mobility, and inflammation at the junctions between the shoulder blade and adjacent bones.
Many people with arthritis find relief through lifestyle changes, exercise, weight control, and medical treatment plans recommended by their doctors.
osteoporosis
Osteoporosis weakens bones and increases the risk of fractures. Although scapular fractures are rare, brittle bones can increase the risk of injury after a fall.
Maintaining healthy calcium and vitamin D levels, regular physical activity, and adherence to preventative measures can help protect bone health.
Heart disease
Many people associate heart problems with chest pain, but certain heart conditions can also cause pain in the left shoulder blade.
Women, in particular, may perceive the symptoms differently than men. In some cases, heart attack symptoms can include the following:
• Pain between the shoulder blades
• Shortness of breath
• Extreme fatigue
• Chest discomfort
• Nausea
If pain in the shoulder blade area occurs in addition to these symptoms, immediate medical treatment is essential.
Lung cancer
In rare cases, pain in the shoulder blade area can be associated with a type of lung tumor, the so-called Pancoast tumor, which develops in the upper part of the lung.
The pain is often persistent and can radiate into the shoulder and arm. Pain that worsens at night, occurs at rest, or has no clear musculoskeletal cause should be examined by a doctor.
breast cancer
Some women with breast cancer report upper back pain between the shoulder blades before other symptoms appear. While shoulder blade pain alone is not a sign of breast cancer, persistent, unexplained pain should be evaluated by a doctor.
Fibromyalgia
Fibromyalgia is a chronic condition characterized by widespread muscle and tissue pain, fatigue, and sleep disturbances. Pain between the shoulder blades is a common complaint among people with fibromyalgia.
What surprises many people is that certain digestive and abdominal problems can also cause pain that feels like it’s coming directly from the shoulder blades.
Gallstones
Gallstones often cause severe pain in the upper right abdomen. However, the pain can also radiate to the right shoulder blade or between the shoulder blades.
liver disease
Liver diseases can cause radiating pain in the right shoulder blade, accompanied by symptoms such as abdominal discomfort, fatigue, and yellowing of the skin or eyes.
Pancreatitis
Inflammation of the pancreas can cause pain below the left shoulder blade. Other common symptoms include nausea, vomiting, bloating, loss of appetite, and abdominal pain that may radiate to the back or chest.
Treatment options
Treatment depends solely on the underlying cause. In the case of muscle tension, symptoms often improve with rest, stretching exercises, posture correction, and avoiding strenuous activities.
More serious illnesses require examination and treatment by a doctor.
Improve your posture
Since many cases of shoulder blade pain are due to muscle tension, maintaining correct posture is important.
Here’s how to check your posture:
• Stand with your back against a wall.
• Your head, shoulders, and buttocks should be touching the wall.
• You should be able to slide your hand along the natural curve of your lower back.
When you are sitting at your desk:
• Keep your back straight.
• Support your lower back.
• Keep your elbows at a 90-degree angle.
• Place your feet flat on the floor.
• Keep your knees at approximately a 90-degree angle.
A simple neck exercise
Since shoulder blade pain can sometimes be related to neck tension, a gentle stretching exercise can help:
Gently press on the sore side of your neck, turn your head away from the pain, and move your chin towards your armpit. Return to the starting position and repeat the exercise 15–20 times.
This simple movement can help reduce neck stiffness and relieve discomfort in the shoulder blade area.
When should you see a doctor?
If you experience pain in the shoulder blade area, seek medical advice:
• Lasts for several weeks
• Worsens
• Occurs after an injury
• Is accompanied by chest pain or difficulty breathing
• Is accompanied by unexplained weight loss or fatigue
Although shoulder blade pain is usually caused by muscle tension or postural problems, it can occasionally indicate a more serious condition. Pay attention to the symptoms and consult a doctor promptly to ensure appropriate treatment and clarity.
