A strained ligament in the shoulder can have the following symptoms: 1. Pain. Pain is usually a sharp tearing pain at the time of the strain, which often requires local cold compresses and oral pain medication to stop the pain. 2. Swelling. Shoulder ligament strains are often accompanied by damage to the surrounding soft tissues, which can lead to swelling and bleeding, as well as localized bruising and ecchymosis. 3. Restriction of movement. After a shoulder ligament strain, there will be a limitation of shoulder abduction, extension, extension and rotation. In addition, an MRI should be performed to further confirm the diagnosis of the shoulder strain.
