Shoulder blade pain is a condition that affects many people and can sometimes be difficult to diagnose. In most cases, the discomfort is caused by something relatively harmless, such as muscle strain or poor posture. However, pain in or between the shoulder blades can occasionally be linked to more serious health conditions, which is why persistent or severe pain should never be ignored.
The shoulder blades, medically known as the 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, identifying the exact source of pain can sometimes be challenging.
Common Symptoms of Shoulder Blade Pain
Shoulder blade pain may occur on one side or both sides of the upper back. The sensation can vary widely and may include:
• Dull aching pain
• Sharp or stabbing discomfort
• Burning sensations
• Pain between the shoulder blades
• Pain that worsens with movement
• Tenderness around the scapula
Sometimes the pain originates directly from the shoulder blade area. In other cases, it may be referred pain, meaning the source is located elsewhere in the body.
Muscle Strain
One of the most common causes of shoulder blade pain is muscle strain. Repetitive activities, lifting, exercise, poor posture, or even sleeping in an awkward position can place excessive stress on the muscles surrounding the scapula.
People who spend long hours performing repetitive tasks often develop chronic discomfort in the upper back and shoulders. Even starting a new exercise routine can place additional strain on these muscles.
Improving posture, taking regular breaks, stretching, and allowing adequate recovery time can often relieve muscle-related shoulder blade pain.
Disc Problems
Degenerative disc disease and herniated discs can also contribute to shoulder blade discomfort.
As spinal discs age, they gradually lose fluid and flexibility. A herniated disc occurs when the soft center of a disc pushes outward and irritates nearby nerves. When nerves in the neck become compressed or inflamed, pain can radiate into the shoulder blades.
Fractures
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.
