First of all, the cause of shoulder pain needs to be clarified, is there any rotator cuff tear or other tissue damage? The diagnosis can be more clearly identified through MRI examination to identify the cause of shoulder pain. For example.
For shoulder pain caused by tendon tears, etc., minimally invasive arthroscopic surgery may be required.
for simple bursitis, it can be treated with physical therapy, oral medication, etc.
For synovitis of the whole joint such as frozen shoulder, rehabilitation, local sealing or arthroscopic minimally invasive surgery is a better approach.
