Swelling
When there’s an internal inflammation [4] of the tendons or bursae, it may show externally. When the shoulder becomes hot, achy, and swollen, it could mean rotator cuff tear or that the tendons are trapped in the scapula. When a person is suffering from bursitis, the swelling irritates the nerves, causing pain and numbness. A swollen shoulder is a sign that there’s an internal disorder that requires your attention. You may need to take an ultrasound scan to know the root cause of the swelling and appropriate treatment to correct the situation.
