Supraspinatus tendonitis is usually caused by fatigue, strain and wind-cold-dampness invasion of the shoulder. Symptoms of supraspinatus tendonitis are pain, tenderness, and limited shoulder motion, especially between 60-120 degrees of shoulder abduction. The area between 60-120 degrees of shoulder abduction, also known as the pain arc of the shoulder, is a symptom specific to supraspinatus tendonitis. The treatment of supraspinatus tendonitis is preferred to shockwave treatment, but can also be treated with microwave, intermediate frequency, infrared and other physical therapy devices, but also can be used in Chinese medicine packs of external application, local external application of creams, such as indomethacin babu cream, pain relief paste cream, through the pain cream and so on. For the acute pain of supraspinatus tendonitis, closed treatment can also be used, but closed treatment is not the first choice, nor is it the best choice. Closed treatment can make the supraspinatus tendon brittle and prone to rupture. For more persistent supraspinatus tendonitis or with symptoms of supraspinatus tendon rupture, minimally invasive arthroscopic treatment can also be used.
