Shoulder periarthritis is commonly referred to as frozen shoulder. It is also known as “50 Shoulder”, “Leaky Shoulder”, “Frozen Shoulder” or “Shoulder Condensation”. Frozen shoulder is a common condition in which the soft tissues around the shoulder joint, including the muscles, tendons, bursa, and joint capsule, are subject to extensive chronic inflammation, resulting in shoulder pain and limited movement. The disease is more common in women than in men, and is more unilateral in onset, with the left shoulder being more common than the right. If not treated effectively, it may seriously affect the functional activities of the shoulder joint. The onset of the disease often has the following characteristics: 1. Early on, the shoulder joint has paroxysmal pain. 2. 2. It is often triggered by weather changes and exertion, and then gradually develops into persistent pain, and gradually worsens. 3. Light day and heavy night. 4.Active and passive activities of the shoulder joint in all directions are limited. 5.When the shoulder is strained, the pain is severe. 6.There may be widespread pressure pain in the shoulder joint and it radiates to the neck and elbow.
