“Periarthritis” of the shoulder

Incorrect name for different tendinitis, bursitis, muscle contractions and other problems around the shoulder. Often it is used for the insertion tendinitis of the supraspinatus and infraspinatus muscles. There are multiple possible causes: functional lesions of the cervical and dorsal spine, falls on the arm or the shoulder with consecutive muscle contractions, malocclusion, thyroid problems, liver or stomach problems, diaphragm contractions, postural and other problems.
