我怀疑是rotator cuff受伤。先约PT检查一下先。热敷比较有用。或者冷热交替。48小时以后不要冰敷

The rotator cuff is a group of muscles and tendons that surround the shoulder joint, providing stability and enabling arm movement. Injuries can range from overuse issues like tendinitis to more severe tears, often caused by repetitive overhead motions, heavy lifting, or acute trauma. Symptoms include pain, weakness, and a clicking sound, and treatments can involve physical therapy, anti-inflammatory drugs, injections or surgery.
