Frozen shoulder is a condition in which the soft tissues around the shoulder joint, such as tendons, muscles, and some soft tissues, develop inflammatory substances that cause shoulder joint pain and even significantly restrict shoulder joint movement. The main reasons for the formation are as follows: 1. The patient is injured, incorrect posture or incorrect exertion causes damage to the local tendons or muscles, which are not well repaired, and even local inflammation and adhesions are produced, causing significant impairment of shoulder joint activities and shoulder joint pain; 2. Local inflammation caused by cold or blow causes local muscle and tendon exudation, forming aseptic inflammation, resulting in local adhesions, which affects shoulder joint activity. Freezing shoulder is a common clinical disease, especially seen in middle-aged and elderly people over 50 years old, so once the above symptoms appear, don’t worry very much, go to a professional therapist to do the treatment and you will be cured.
