我懷疑是rotator cuff受傷。先約PT檢查一下先。熱敷比較有用。或者冷熱交替。48小時以後不要冰敷

 

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.
