Physiological rattling: If there is only rattling in the shoulder joint, no obvious pain and normal activities, it is a normal phenomenon and does not need to be treated. 2. Shoulder labral tear: Strenuous exercise may cause shoulder labral tear, resulting in shoulder pain, popping, difficulty in movement, etc. Surgery is needed to repair the damaged labrum. 3. Tendon injury: Strenuous exercise may cause tendon injury such as biceps long head tendon, which may cause pain and popping in the shoulder joint. If the injury is mild, you can rest appropriately, but if the injury is heavy and the ligament is ruptured, you need to rebuild the ligament by surgery. 4.
