Shoulder muscle pain can be relieved and treated by medication or surgery. However, as there are many factors causing shoulder muscle pain, such as shoulder joint trauma, cervical spondylosis or frozen shoulder, the treatment will be different, as follows: 1. Shoulder joint trauma: If shoulder muscle pain is caused by shoulder joint fracture, shoulder joint dislocation or rotator cuff tendon tear and other shoulder joint trauma, it is necessary to determine the location and degree of injury through X-ray films and repair and treat it through surgery. 2. Cervical spondylosis: If the cervical spondylosis is of the nerve root type, it will also cause radiating pain in the neck and shoulder area and lead to the restriction of cervical spine activities, patients can exercise the neck and shoulder muscles and combine with anterior and posterior surgeries to relieve the treatment. 3. Frozen shoulder: Frozen shoulder is a self-limited aseptic inflammation of the soft tissues around the shoulder joint due to unknown reasons, which is mainly manifested as pain and activity limitation of the shoulder joint, and it can be relieved by taking drugs such as etoricoxib tablets, ibuprofen delayed-release capsules, meloxicam tablets and so on, and it can be treated by open surgery or minimally invasive arthroscopic surgery if necessary. As there are many causes of shoulder muscle pain, it is recommended to go to the hospital for examination and diagnosis when symptoms occur, so that the cause of the disease can be clarified as soon as possible and targeted treatment measures can be taken to avoid worsening of the symptoms.
