Hi there and thank you for your question. The general term for this issue would be a rotator cuff tear of the shoulder. If mild symptoms are experienced then intra-articular infiltration with cortisone could help but it would only offer temporary relief. The pain would improve and so would joint movement but it won t do anything to the tear. Although it s only a partial tear that s involved, it can develop into a bigger or even a complete tear in the long term due to persistent inflammation. If the pain becomes worse and mobility of the shoulder becomes more limited then it would be a good idea to consult an orthopedic surgeon. Management could include repair of the tear through arthroscopic surgery with post procedure physiotherapy. I hope this helps answer your question and good luck.
