What illness causes pain in the left front chest and left upper back near the shoulder blade?

Pain in the left anterior chest and left posterior back near the scapula may be caused by conditions such as myofascial inflammation, shoulder periarthritis, cervical spondylosis, and others. Specific analyses are as follows:

1. Myofascial Inflammation

When the left anterior chest and the left upper back around the scapula are exposed to triggers such as cold, dampness, or excessive fatigue, localized muscle tension may develop, compressing surrounding nerves and provoking an inflammatory response that leads to pain.

2. Shoulder Periarthritis

Injury to the shoulder joint capsule, as well as surrounding ligaments, tendons, and bursae, can easily cause chronic inflammation, resulting in shoulder periarthritis. Without effective treatment, the condition may worsen, increasing pain intensity and expanding its range, radiating to the chest and scapular regions, causing pain and restricted movement.

3. Cervical Spondylosis

Cervical spondylosis commonly causes symptoms such as neck and shoulder pain and stiffness. If left untreated, symptoms may progress and lead to radiating pain, resulting in discomfort, numbness, or pain in areas such as the left anterior chest, left posterior back near the scapula, and upper limbs.

In addition, conditions such as pneumonia, cholecystitis, and pleurisy may also cause similar symptoms. It is recommended to visit a hospital for a thorough examination to determine the exact underlying cause and receive targeted treatment.
