Although relatively uncommon, fractures of the scapula can occur following major trauma such as vehicle accidents or severe falls. These injuries require immediate medical evaluation because they are often associated with other serious injuries.
But muscle strain and spinal issues are only part of the story—some surprising medical conditions elsewhere in the body can also trigger pain in the shoulder blades.
Arthritis
Osteoarthritis is a degenerative joint condition that can affect the joints around the shoulder blade. It may cause pain, swelling, stiffness, reduced mobility, and inflammation where the shoulder blade connects to nearby bones.
Many people with arthritis find relief through lifestyle changes, exercise, weight management, and medical treatment plans recommended by their healthcare providers.
Osteoporosis
Osteoporosis weakens bones and increases the risk of fractures. Although scapular fractures remain uncommon, brittle bones can make injuries more likely after a fall.
Maintaining healthy calcium and vitamin D levels, staying physically active, and following preventive measures can help protect bone health.
Heart Conditions
Many people associate heart problems with chest pain, but certain cardiac conditions can also cause pain in the left shoulder blade.
Women, in particular, may experience symptoms differently than men. In some cases, heart attack symptoms may include:
• Pain between the shoulder blades
• Shortness of breath
• Extreme fatigue
• Chest discomfort
• Nausea
If shoulder blade pain occurs alongside these symptoms, immediate medical attention is essential.
Lung Cancer
In rare cases, shoulder blade pain can be linked to a type of lung tumor known as a Pancoast tumor, which develops near the top of the lung.
The pain is often persistent and may spread into the shoulder and arm. Pain that worsens at night, occurs at rest, or has no clear musculoskeletal cause should be evaluated by a healthcare professional.
Breast Cancer
Some individuals with breast cancer report upper back pain between the shoulder blades before other symptoms become noticeable. While shoulder blade pain alone is not a sign of breast cancer, persistent unexplained discomfort deserves medical assessment.
